Strange behavior of audio subsystem after update Dev Alpha 10 to 10.0.9.388

Hello world!

Has anyone noticed a strange behavior of the behavior of 10.0.9.388 audio subsystem firmware. Recently, after firmware update Dev Alpha 10 to 10.0.9.388 subsystem audio misbehavies in the following way:

(1) if the external headphones/speakers connected to the audio line-out looks to be preprocessed by low-pass filter and surround effect. The device reported by AudioManager is/dev/snd/pcmPrefferedp. Would it be a bug in formware and re-routing audio internal speaker to the line-out socket did not exclude specific pre-treatment?

(2) on the previous firmwares if audio goes out of the internal speaker and then the helmet is connected to Jack line out change of itinerary was seemlesly happening and he kept playing with headphones without additional measures in the application. Now, peripheral audio is not consume audio samples and so crashes until it is closed and reopened.

On the previous firmwares were not all the problems of this kind. Would be - what a few unlucky flashing firmware try (if it is still possible) or bug of 10.0.9.388.

It will be good to hear comments & thoughts about these questions.

Best regards

Dmitry.

  • After wiping Dev Alpha, it gets stuck

    Now when it restarts, it shows a litte with a USB phone to a computer. When I plug it into the USB or the phone or the computer acts as something that happened.

    If I don't touch it, the dev alpha turns off, then when I turn it on again, same thing the usb screen. I need to finish a few apps and test them, I don't know what to do. Can someone help me?

    The automatic charger for Windows and connect the device to the computer windows using a US cable. Run the automatic charger. It starts by itself. If this isn't the case, keep the button of the unit alpha dev for at least 15 seconds.

  • Strange behavior of the mouse after installing the updated driver

    Hello

    Windows Update suggested that I update the mouse and/or the keyboard driver detection. I don't remember the exact message.

    Also, I find no trace of this update in the box "Installed updates". It seems that the driver updates are not included.

    Symptom: Periodically, the screen scrolls upward around 3 lines, even through I'm even not touching the mouse. It's like the wheel was scrolled beyond a tick.

    This has never happened before this update of detection has been installed.

    Windows 64-bit Enterprise, USB Intellimouse Optical 1.1

    How can I find the update has been installed? How can I remove it?

    Thanks - ankle

    Hi MaskedAnkle,

    Thank you for using Microsoft Windows forum.

    If you want to see the updated story to update try the following steps to check the update has been installed for programs.

    1. open the control panel (all items view), and click the Windows Update icon. (See screenshot below)

    2. click on the link to view update history. (See screenshot below)

    3. to view the details of a single Windows Update-

    (A) select and right-click on a Windows Update list, and then click details. (See screenshot below step 4)

    (B) click on close when finished. (See screenshot below)

    4. to copy the details of an update of Windows unique to Clipboard-

    (A) select and right-click on a Windows Update list, and then click details.

    NOTE: It will be the same details in step 3, but in a text format instead.

    (B) you can now copy the contents of the Clipboard (ctrl + V) in a program such as Notepad or WordPad.

    If you think that the problem occurred after the installation of the update of the driver, you can restore the mouse driver and check if that helps.

    Steps to roll back a driver:

    #Open Control Panel Windows Device Manager.

    Manager #In of devices, look for the device that you want to restore the driver.

    #After find the material you are roll back the driver, right click on the name or the icon of the device and click Properties.

    #In the properties of the device window, click the driver tab.

    #On tab driver, click on the button return to the previous version.

    Note: If the button return to the previous version is disabled, Windows 7 doesn't have a previous driver to roll back to then you will not be able to complete this process.

    #Click the button Yes to the question "Are you sure you want to restore the driver previously installed software?".

    We now find the driver already installed. You should see the button return to the previous version is disabled when the roll back is finished.

    #Click the close button at the bottom of the screen of the device properties.

    #Click Yes in the system settings change dialog box that says: "your hardware settings have changed. You must restart your computer for these changes to take effect. You want to restart your computer now? »

    If this message is hidden, the close window command panel might help. You will not be able to close the Device Manager.

    Note:
    you are according to the device driver roll back, it is possible that you will not need to restart your PC. If you
    do not see the message, consider the complete rear roller.

    #Your computer will now restart automatically.

    When Windows 7 starts up again, it will load with the device driver of this material that you had previously installed

    You can also try the system restore if the problem persists,

    Do not know exactly if that's when it happened (update of windows 7) but now when I go in the editor of virtual network, or add a new network or simply modify an existing one, the one I hit

    Any IP field I try to edit/change I can only add two numbers. If there already 3 and I stress and variation 1 of them I can do that two digits by field.

    Then 192.168.100.0 and try to change the TI 100 to 101 going to 10, can I change the 10 to 99, 40 any other number but not a 3 digit number.

    This happened on the workstation 10 if I support (uninstalled) reved and re-installed WS 9 same behavior.

    Anyone else seeing this?

    Thank you

    Found. If I use a custom DPI setting (or 134% of normal), I get the funky behavior.

    If I use the default or 125% setting, everything is good.

    Returned to the standard windows display driver just to see if the same thing and it was (NVidia card) vs NVidia GEForce driver

  • The scrolling behavior is not smooth after update to Mac OS Sierra

    After that the macOS update Sierra the scrolling behavior has changed, does anyone have same experiences?

    I can still scroll trough a Web page without a problem. I mean the scroll with 2 fingers on the touch pad or scroll with the magic mouse gesture.

    BUT: In trying to slowly scroll through long lists of selections, just answers touching on fast movements, not on the slow change.

    Steps to reproduce:

    Open a Web site like twitter and go to preferences. Go to the time zone list, open it, and scroll through it. Can you move the cursor to line by line?

    You can also move to http://www.doyouspain.com/mietwagen/ , select a country like the Spain a try to SLOWLY scroll list.

    (I just discovered: the list of operating system at the end of this page shows the same problems with PCMCIA)

    I found this behavior using "Parallels Desktop". I can't scroll the documents most as before the update.

    Hello!

    Please open the accessibility, to increase the scrolling speed move the slider from slow to fast (from left to right).

    A screenshot for reference.

Look in the Control Panel, the IDT device is considered taken ok, if I check the audio devices - there is none. The speaker icon is red with a cross. I tried to reload the original device driver & that makes no difference, I also tried the latest driver - no change. It was working fine until I was invited to be updated - yuk.

    Any ideas - ciao Tom

    You are the very welcome, Tom.

    Sorry, that didn't work.

    Something does not seem just to get a system restore disk error, and now the checkdisk is frozen.

    Unfortunately, I don't have any other suggestions for you to try.

    If the checkdisk remains frozen, you won't the choice but to shut down the PC and see if it will reboot.

    I wonder if it is possible the hard drive failed on you.

    I have seen a lot of posts on this same problem with Maxx Audio in Windows 10, however, I tried to fix it by trying different solutions, that users have given and I had no chance. I uninstalled the driver and reinstalled the Dell expects W10 and Maxx Audio controls do not work. Someone said that they have installed the old drivers for W8.1 and it worked again, I tried it and the controls are there, but when I try to disable Audio Maxx, it does nothing and I close the window, open again and the bar is activated if, it turns off. No idea if I'm doing something wrong? It's a problem very annoying for me since I work with many audio and now it sounds just awful! :(

    Much to my anger and regret, Dell didn't send any form of notification NO update to the platform Windows 10 and I did, then reverse it after seeing what a nightmare Windows 10 has, however, not only is now my audio DOES NOT WORK, but my departure to the top and stop sequence is ruined as well as on my laptop Dell.  I tired many times to count to reinstall the drivers for the audio, but it doesn't seem to recognize the audio driver of Dell on Microsoft which is also...

  • Cisco AnyConnect Secure mobility Client cannot initialize connection subsystem after updates Windows (Feb 10, 2015)

    Hello

    The customer Cisco Anyconnect Secure mobility gives me an error when I try to use it. It started after the latest updates for Windows (10 Feb. 2015).

    The error it causes is "could not initialize the subsystem of connection".

    I looked at another machine with the updates installed with same issue.

    On my machine - I back before restore point windows updates be done, and the Cisco Anyconnect Client's worked well.

    After you install the updates, it stopped working again.

    Help, please

    Michael

    I assume you are using Windows 8.1. The workaround is to set the AnyConnect Client to use Windows 8 Compatibility Mode. He has worked on several machines. After the change, you will need to log off the coast and turn it on for Windows.

    Cumulative update 11 IE KB3021952 includes KB3023607.  Apparently, it's the latest patch that causes the problem, according to what I said. (I do not even 3023607 in the history of WU, but if I type "wmic qfe" is here). However, I suggest updating leaving in place and using workaround.

  • strange behavior of audio w/new AVCHD Sony HXR - NX5U CAMCORDER

    Help, I just unpacked it my Sony HXR - NX5U AVCHD CAMCORDER.  All was well with the video, the CMU software, etc.  I have CS5 on the way, but for now still use CS4.  I've implemented the project with 1080i30 (60i) AVCHD.  I import my video and the image looks fine, but the audio is all WHISTLE - total clipping.  I listened to the file with the software of Sony CMU and this seems perfect.  I eliminated the error camera using multiple microphones, mike internal headset sounds good and once again, with the software the normal sound Sony CMU m2ts files.  What I am doing wrong?

    Any help would be appreciated because I really want to use this camera tonight.

    Kind regards

    Lisa

    How (step by step) you receive files from the camcorder to the body?

    For my Canon Vixia, I simply use WinExplorer to copy the MTS files from an SD card on hard disk and then import them in CS5

    For other cameras, I read that required "metadata" are contained in the folder structure, so a complete file should be copied from the camera to the computer... often or sometimes by using the software provided with the camera, because it is designed to do a "copy."

  • Z10 blackBerry I can't update dev alpha b

    and now I can't put another firmware update:

    Thank you.

    I did not understand how to solve this problem.
    I tried to update my camera 30 times.
    I removed the battery for a long period of the unit.
    Then I tried to update my device with a battery and without battery.
    Without ceasing to 29 times the process arbitrarily after having turn off the green light on the device.
    The last time the device was 10 minutes without the battery.
    Then I hung device to the computer and tried to update my device without the battery again.
    And this time the upgrade process completed successfully.

    Now the camera works.
    But I don't understand why this process finished, because I didn't do something again.
    I think it's just a mystery, because I still don't understand why.

    The main thing is that the my device works now and I can test my apps on it.

    I am very happy.
    Thanks to you all.

  • Audio dev Alpha C Cup using OpenAL

    Hello

    I have some problem with the audio on my device Dev Alpha C and I was wondering if anyone else has had or similar problems or that he might be able to offer a solution.

    The problem

    When you run our game on a device Dev Alpha C, after a short period the sound effects cut. After that no sound effects are played once again, apart from very occasional snippets of sounds, as the device is trying to play them but quickly to cut again.

    The strange thing is that the same code works fine on the Alpha of A Dev.

    Implementation

    The sound effects are implemented using OpenAL and OpenALUT.  Our music is played using the multimedia rendering engine (and works very well).  I checked for errors from OpenAL, but it is not everything.

    Our installation of OpenAL is quite simple and in fact is the following (note that I cut an error handling form all my code samples for brevity):

    if(alutInitWithoutContext(NULL, NULL))
    {
        device = alcOpenDevice(NULL);
        if(device != NULL)
        {
            context = alcCreateContext(device, 0);
            if(context != NULL)
            {
                alcMakeContextCurrent(context);
                alGenBuffers(MAX_SOUND_BUFFERS, buffers);
                alGenSources(MAX_SOUND_CHANNELS, sources);
            }
        }
    }
    

    Sounds are then loaded by:

    void *data=alutLoadMemoryFromFile(filepath.c_str(), &format, &size, &freq);
    alBufferData(buffers[bufferIndex], format, data, size, freq);
    

    (There are some parameters of sound parameters that I haven't posted because I don't think that is where the error but I can add it if it could be relevant to reprogramming).

    Finally the sounds are played using

    alSourcePlay(sourceNum);
    

    I use SDK 10.1.0.1020 and Dev Alpha C is on the firmware 10.1.0.138.

    If anyone has any suggestions, they would be welcome!

    On the problem of origin, was published a new firmware which seems to fix the problem. You can find it here: https://developer.blackberry.com/blackberry10devalpha/devalpha_update.html.  I tested it on our Dev C Alpha and it seems to work very well - I'm always test so will update if I have problems, but it seems OK so far.

    @beemaster - you might want to consider posting this question as a separate topic, as there is a good chance of people won't find it in this thread.  For what it's worth, we use MP3s in our game very well, even if we don't use of stunts and use the multimedia rendering engine to play, which could explain the observed differences.

    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.
