• HP 15: Audio distorted after upgrade to Windows 10 Anniversary Edition

  Hey everybody,

  I just upgraded my laptop HP15 for Windows 10 Anniversary Edition. Now, I have distorted audio, is there something I can do to fix that?

  Thank you

  Bill

  @Bill_F

  After the upgrade to the anniversary edition the first thing I recommend is to update your drivers and software via Windows Update and HP Support Assistant.

  For some specific models of HP, there may be difficulties with audio destortion after update of the anniversary. Please see the following support document to see if your model in the series is in the list and the instructions to follow.

• Major Frame Drops after 5-10 minutes

  Hello world

  I'm really frustrated here, I'm a game developer, and I use the GPU in almost all cases, from Photoshop to unity still play games myself. Since the last update 10.11.4 I have this huge problem , and everything I do will not disappear.

  Whenever I run an application / game that rotates with GPU I get spikes massive lag and thus Frame Drops, they last about 1 seconds but they occur every 30 seconds - 1 minute, this is a huge deal for me and I can't really work like that. Of course, I put photoshop to the CPU usage for now and no problems. But I really need to work efficiently and without Frame Drops.

  I run at El Capitan with a Macbook Pro LATE 2013 10.11.4 @.

  Before someone says I should have got the Nvidia gpu, I should mention that I tried on 2 games to 1 which I played with ease previously:

  Hand of fate

  The Witcher: Enhanced Edition

  Please if someone else has the same problem, make sure that post you here. It bothers me that I have not found anything about the case.

  1. the present proceedings is a diagnostic test. It doesn't change anything for the better or worse and therefore, by itself, will not solve the problem. But with the help of the results of the tests, the solution may take a few minutes, instead of hours or days.

  The test works on OS X 10.8 ("Mountain Lion") and later versions. I do not recommend running it on older versions of Mac OS X. It will do no harm, but it will not do not much good.

  Do not be put off by the complexity of these instructions. The process is much less complicated than the description. You make the tasks more complicated with the computer all the time.

  2. If you do not already have a current backup, please back up all the data before doing anything else. The backup is needed on the general principle, not because of what anyone in the test procedure. Backup is always a must, and when you encounter any kind of problems with the computer, you can be more than the usual loss of data, if you follow these instructions or risk not.

  There are ways to back up a computer that is not fully functional. Ask if you need advice.

  3 here is instructions to run a UNIX shell script, a type of program. As I wrote above, it doesn't change anything. It does not send or receive data over the network. There is no to generate a report on the State of the computer human readable. This report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents for me or someone else.

  You should ask yourself if you can believe me, and if it is safe to run a program at the request of a foreign national. In general, no, he's not sure, and I encourage it.

  In this case, however, there are ways for you to decide if the program is safe without having to trust me. First of all, you can read it. Unlike an application that download you and click to start, it is transparent, anyone familiar with the code can check what it does.

  You may not be able to understand the script yourself. But variations of it have been posted on this site several times over a period of years. One of the million registered users to have read the script and set off the alarm if it was dangerous. Then I wouldn't be here now, and you would not be reading this message. See, e.g., this discussion.

  However, if you cannot satisfy yourself that these instructions are safe, do not follow them. Ask other solutions.

  4. here is a general summary of what you need to do, if you decide to go forward:

  ☞ Copy text from a particular web page (not this one) to the Clipboard.

  ☞ Paste into the window to another application.

  ☞ Wait for the test to run. It usually takes a few minutes.

  ☞ Stick the results, which will be copied automatically, in a response on this page.

  These are not specific instructions; just a glimpse. The details are in parts 7 and 8 of this comment. The sequence is: copy, paste, wait and paste it again. You don't need to copy a second time.

  5. try to test in conditions that replicate the problem, to the extent possible. For example, if the computer is slow intermittently, run the test during a downturn.

  You may have started up in safe mode. If the system is now in safe mode and works pretty well in normal mode to test run, restart as usual before running it. If you can test only in safe mode, this.

  6. If you have more than one user and a user is affected by the problem, and the user is not an administrator, and then run the test twice: once under the affected user and one administrator. The results can be different. The user that is created automatically on a new computer, when you start it for the first time is an administrator. If you are unable to log in as an administrator, verify that the user concerned. More personal Mac have only one user, and in this case this section does not apply. Don't log in as root.

  7 load the linked web page (the site "Pastebin.") Press the combination of keys command + A to select all the text, then copy it to the Clipboard by pressing command-C.

  8. start the Terminal application integrated in one of the following ways:

  ☞ Enter the first letters of his name ("Terminal") in a Spotlight search. Select from the results (it should be at the top).

  ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

  ☞ Open LaunchPad and start typing the name.

  Click anywhere in the Terminal window to activate it. Paste from the Clipboard into the window by pressing Command + V, then press return. The text that you pasted should disappear immediately.

  9. If you logged in as an administrator, you will be prompted for your login password. Nothing displayed when you type. You won't see the usual points instead of the characters typed. Make sure that caps lock is turned off. Type carefully, and then press return. You can get a warning to be careful. If you make three unsuccessful attempts to enter the password, the test is still running, but it will produce less information. If you do not know the password, or if you prefer not to enter, just press back three times at the password prompt. Yet once again, the script will run.

  If the test takes much longer that usual to run because the computer is very slow, you can be prompted for your password a second time. The permission you grant by entering it will expire automatically after five minutes.

  If you are not logged as an administrator, you will be prompted for a password. The test will run. It just will not do anything that requires administrator privileges.

  10. the test may take a few minutes to run, depending on the number of files you have and the speed of the computer. A computer that is abnormally slow may take more time to run the test. During execution, a series of lines is displayed in the Terminal window like this:

      Test started

          Part 1 of 4 done at: … sec        …        Part 4 of 4 done at: … sec

      The test results are on the Clipboard.

      Please close this window.

  The intervals between the parties will not be exactly the same, but they give an approximate indication of progress.

  Wait for the final message "Please close this window" appear - again, usually within a few minutes. If you don't see this message in about 30 minutes, the test probably won't be completed within a reasonable time. In this case, press the Ctrl + C key combination or the point command to stop it. Then go to the next step. You will have incomplete results, but still something.

  In order to get results, the test should be allowed to perform or be stopped manually as shown above. If you close the window of the Terminal, while the test is still running, the partial results will not be saved.

  11. when the test is completed, or if you manually stopped, leaving the Terminal. The results have been saved to the Clipboard automatically. They do not appear in the Terminal window. Please do not copy from there. All you have to do is start a response to this comment and then paste it again by pressing Command-V.

  At the top of the results, there will be a line that begins with the words «Start time.» If you do not see that, but rather to see a mass of gibberish, you wait for the message "close this window". Please wait and try again.

  If personal information, such as your name or e-mail address, appear in the results, make anonymous before posting. Usually it will be not necessary.

  12. in the validation of the results, you see an error message on the web page: "you have included content in your post that is not allowed", or "the message contains invalid characters." It's a bug in the software which manages this website. Thanks for posting the results of the tests on Pastebin, then post here a link to the page you created.

  If you have an account on Pastebin, please do not select private in exposure menu to paste on the page, because no one else that you will be able to see it.

  13. When you are finished with the test, it is gone. There is nothing to uninstall or clean.

  14. This is a public forum and others can give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but all that you can not be. For others who choose to run it, I do not recommend that you view the results of test on this Web site unless I ask.

  15. the related UNIX shell script is a notice of copyright. ASC readers can copy for their personal use. The whole nor any part can be redistributed.

• Latitude E5520 Audio problems after upgrade to win 10

  I have audio problems after upgrade to win 10 64-bit.

  (1) if I use the built-in driver to Win 10 ("high definition Audio Device") I hear speakers/headphones and switching between the speakers and the works of helmet very well but my laptop computer microphone does not work ("not connected").

  (2) if I use the latest Dell driver (IDT 92HDxxx HD Audio Driver) I hear initially via speakers, but as soon as I plug in headphones I can't switch back to the speakers (i.e. switching between the speakers and the headphones does not work) and my laptop computer microphone works.

  I would be happy to provide more information and help to debug.

  To a Microsoft Community Forum, I received the following reply from Rob Brown - Microsoft MVP:

  AS OEM Dell is responsible for the good operation of the equipment both
  and Windows.

  Hi, John. It's quite nervous of a member of the MS forum say that Dell is responsible to operate Windows. It wasn't Dell but MS who claims that Win10 has most of the necessary drivers and if not then the drivers Win7 and Win8.1 would work.

  johnsdagg

  I was hoping that maybe Dell could find in the goodness of their hearts to a updated driver IDT 92HDxxx... pretty please?

  I doubt that it is possible for two reasons. Dell went from IDT Realtek as the audio seller so probably not more a a contract with IDT, if IDT even exist anymore. A year ago IDT was acquired by another company. I do not know its current status, but it is sure that the acquiring company will not be upgrading old software IDT. Reference Dell itself does not write the audio drivers. Even when IDT was the seller I believe that Win7 drivers are the final versions - no version 8 or 8.1 I think.

  johnsdagg

  If I use the built-in driver to Win 10 ("high definition Audio Device") I hear speakers/headphones and switching between the speakers and the works of helmet very well but my laptop computer microphone does not work ("not connected").

  The native Windows audio driver can't stand struggling external mic. It is a MS 'known problem '. MS must implement a decision-making support, but there is no indication that it will be. Meanwhile, you have two workaround solutions. You can switch backwards between the natives and the IDT drivers. At some point Win10 could leave the IDT driver works correctly. Or get an outlet cheap usb audio to the microphone. Struggling running out-audio driver usb Windows native usb and so dependent no driver IDT.

  Make sure you check you SIP Trunks and SIP configuration on CUCM routing model.

  Make sure that your points in routing SIP Trunk SIP of Point Application model.

  Make sure that the Partition configured in routing SIP model belongs to a CSS that is configured in the LoadBalancing SIP trunk under:

• VPN users drops after every 5 minutes

  Hello world

  We have users whose remote VPN drops after every 5 minutes.

  I need to know what things can check to solve the problem?

  The user connects by RSA Token.

  ISP connection is ok is not question.

  Something I can verify in SAA?

  Thank you

  Client side, have you tested wired vs wireless to see if the problem exists in both?  If it's the only one, but not the other, try to update the drivers.  Also, if it's windows 7, take a look at the power settings in the control panel.  I saw where the aggressive powers will be stop standby network port.  Not that big of a deal in a LAN environment but it wreaks havoc on the VPN.

• H323 incoming call drops after 5 minutes each time

  Hi people,

  Can you shed any light on this please?

  H.323 incoming call (numbering by IP)-> external F5-> Fortinet Firewall-> internal F5-> internal firewall-> VCS - E-> VCS - C-> autoattendent MCU

  The call drops after 5 minutes into the call, every time. We tried H.323 call to an internal endpoint, it falls as well. Looks like there is a value of the time-out period defined somewhere on firewall he or F5?

  Any suggestion is appreciated!

  concerning

  Chenzhe

  I hope this helps:

  http://www.Cisco.com/c/en/us/TD/docs/Telepresence/infrastructure/article...

  1. Term applied to network connections through the firewall limits. For example, a Cisco PIX firewall can have a timeout of the form control:

     timeout conn 1:00:00 udp 0:02:00 h225 1:00:00 h323 2:00:00

     (i.e. a list of names of Protocol recognized each followed by a timeout in hours, minutes, and seconds). This example requires a limit of 2 hours on the H.323 connections; However, it also imposes limits on the other protocols, which would also affect a video call (UDP and H225). Several different network protocols are involved in an IP video call. The call being demolished may cause a delay applied to all of them.

• Audio popping after burning blu - ray in 5.1

  Just as a warning, I'm relatively new to Adobe Premiere and I'm under first Elements 8 on a Sony Vaio with a processor of Intel Core i5 - 580 M, GPU ATI Mobility Radeon HD 5650, 8 GB DDR3 - SDRAM - 1066 and Windows 7 Home Premium 64 - bit.

  I'm trying to create discs blu - ray full HD and 5.1 surround sound. Video source is full HD 1920 x 1080 with. Extension M2TS. When I have Adobe Premiere Elements 8 check the properties for my videos, it says the audio format of the source is "48, 000Hz - compressed - 6 channels" and the audio format of the project is '48, 000Hz - 32 bit floating point - 6 channels. This is despite the fact that the source is 5.1. However what edition of videos "5.1" appears next to the audio 1 on the timeline. I read something on this issue, and I guess that it is not the cause of any audio bad after an engraving of blu - ray.

  I create new projects using these settings:

  NTSC-AVCHD-Full HD 1080i 30 5.1 channels

  After a few quick changes I burn a disc blu - ray with 1920x1080i THAT NTSC Dolby H.264 preset. When checking of the combustion quality video looks great but audio has a distinct bursting or cracking sometimes that isn't in the file source at all. Someone has any ideas why a burn causes these audio imperfections appear? I've never had problems with burns from channel 2 and I'll probably just end up sticking with 2 audio channels, if a solution cannot be found. Note, the audio output is also much lower than the burned copy when read from the source file. This occurs even when the volume of the clip is set to the max of + 6.0dB. Thanks for any help.

  First of all, the pre can't burn, or the share of the export/DD 5.1 SS Audio. PrPro even needs additional Minnetonka Audio SurCode 5.1 DD SS pluginto export this Audio stream. Pre can work with DD 5.1 SS in many project Presets, but will need mixer 2 channel for export, or to burn.

  Now, when we make cuts on the Audio files and the ends upwards, and cuts do not run from "zero crossing", you can pop or big ticks. It's the lack of continuity in the Audio waveform - not at zero crossings. Usually, these reductions based on crossing zero setting will eliminate the POPs and clicks.

  Good luck

• Pilot hole: speed and height increase after audio dropping during A2DP streamin

  When there is an audio fall (which happens from time to time) while listening to music A2DP, the pilot trying to 'keep up' once the connection has been restored. It does this by pressing the audio so that both audio speed and pitch are increased. So what I mean is: audio interruption, the continuous music, speed and height increasing, after about two seconds the speed and not lower level back to normal.
  It is a very bad audio experience.
  The right thing to do would be to drop audio samples completely which should have been passed in these hundreds of milliseconds rather than keep them.

  Similar experiences?

  BTW, I use headphones JBL REF610.

• Video and audio problem after upgrade of Sierra.

  After that each OS upgrade that I know it's going to be a few problems, so I wasn't surprised when this happened with Sierra. Most have been quickly resolved by common sense, but I have a biggie that remains. Mainly, but not only, it occurs during playback of videos and translates into a serious attack.

  When you use: -.

  Google Chrome Version 53.0.2785.116 (64-bit);

  When you watch a video, I hear a short hissing sound with a rising intonation (or sometimes 2 these sounds) then the text is added to a search bar (sometimes this text contains the words drawn from what someone says in the video!), or the video play suddenly disappears and a new tab opens and opens a page of Google apps. By clicking on the symbol left back page Apps and re - opens the original video that starts playing from the beginning again.

  This happens also in Chrome when it suffice to read a web page.

  In Safari 10.0 (12602.1.50.0.10)

  When occurs sound even watch videos in Safari 10.0 (12602.1.50.0.10), and the small text boxes appear at the top of the screen for a few moments contains comments such as "Hide this app", or "Undo that" before disappearing again.

  and audio in iTunes 12.5.1.21

  The same thing is happening in iTunes or when playing the iStore clips or songs in my library. The same small text boxes are displayed at the top middle of the screen containing cryptic messages such as "click 308' disappearing quickly. Sometimes the ' find and Replace window appears with more cryptic phrases in ' are are are ' not found! This occurs every 3-4 minutes.

  When you use Pages 6.0, a doc Pages will disappear and will appear in the folder from which it was opened. Or Graphic Converter 8, an image suddenly disappears and will open the Finder.

  I ran Etrecheck that says everything has been "excellent". I ran disk utility: first aid, who said there is corruption, he couldn't fix it and is running in recovery mode. I did, and the glitches always come back.

  Summat is false and I am not enough techno to understand (or maybe even explain it very well).

  Anyone bed this litany has an overview of what happens with a recourse?

  Thank you very much
