• No audio signal through HDMI (dv9700t CTO)

  HP Pavilion dv9700t CTO Entertainment Notebook PC / Windows Vista 64-bit

  I put the audio device by default for the device "Realtek Digital Output. I have no sound.

  I've updated the audio drivers on the HP support site. Still no sound via HDMI. (the microphone quality was reduced at the point of being worthless)

  I have updated the drivers with drivers from the site Web of Realtek. Still no sound via HDMI. (I found micro feature)

  The box of bolt that I'm trying to connect to indicates that there is no audio signal passed him from this source (my laptop). I even tried to connect directly to the tv. Which doesn't work anymore.

  Its almost as if there was no link between the audio and HDMI port.

  I have dv9758ca and I have the same problem. No sound with the yamaha receiver. I sound with my LG TV and I tried with an Onkiyo recevier and it worked.

  Once I had the sound on the yamaha (was a flook). the image was running on the TV and the screen of the computer (which is not normal) at the same time. then I concluded that the problem is the HDCP protection. the yamaha recevier is HDCP.

  I've still did not know what the solution is, I just wanted to share my experience

• Toshiba 32TL933G: No Audio signal in PC mode

  Hello

  I connected my laptop VGA to entry-level PC TV and the Audio output of the laptop to TV Audio IN.
  No Audio in PC-Modus!

  Is it possible to go from Audio IN to the PC Input?
  Now I have a video in PC * GOLD * Sound in EXT2, not together.
  IF not, I will return it

  Nevertheless a beautiful Asian.

  The fact is that VGA port does not provide the audio but video signal only.
  So if you a TV connected to the computer laptop s port VGA, audio signal would not be provided.
  You need connect the TV with an extra audio cable in order to get the sound.

  The laptop must be connected to the TV s L R taken audio using an audio cable additional of Y. So that you can connect to s portable headphone plug to two L R audio ports that are available on the back of TV s

• Converts the audio signals of the mydaq in discrete values

  Hi guys!

  I'm currently building a project that accepts mydaq audio signals. I wanted to analog signals it have descrete peak values. Is this possible? I intend to use the discrete peak values and sum their place by using a registry change instead of the peaks. I think it is easier.

  Any suggestions would be helpful. Thank you very much!

  "".. "in the end we all hopes"...

  Yes it detects peaks. but I can't use the peaks detected for something else. He's right there showing me the summits. But I wanted to use these pics for something else, and then to summarize. If there is anything I can do in the peaks detected so that I can use it and summarize, please tell me.

  Yes, the Ridge detector shows you where are the tops.  Now use a loop FOR autoindex on where are the tops for the level in those places.  Now you have a table to the top.  You can then use add table items to add them together.

• NOR-USB 9229: How audio signal acquisition?

  Hello

  It's one of those stupid beginner questions I use a module OR 9229 USB to capture the audio output of my computer line as follows:

  -left line-out goes to AI0 +.

  -right line output goes to AI1 +.

  -land line out of is divided into two and goes to AI0 - and AI1 -.

  What is the correct way of wiring?

  In case it is, I have (I think) have problems audio signal acquisition. In the Measurement & Automation Explore, I creates a task for the acquisition of voltage AI0 (44100 Hz, etc.) -nothing is displayed on the graph when I run the task! (I have music running on the computer during the measurement) Otherwise, the 9229 flashes green, seems to be ok, auto test work, etc..

  Someone has an idea what I am doing wrong?

  Thank you!

  Hi acgrama,

  That sounds like it should give you a signal any (not an empty graph or a flat line at 0 V), but the USB-9229 is not very suitable for audio:

  • The USB-9229 to entry level is of +/-60 V. A line level audio signal will use a small fraction of that. Of the USB-9229 precision and plug noise are adequate for your application?
  • The USB-9229 can't acquire them exactly 44.1 kech. / s. It supports some 50 kech sampling frequencies. / s divided by a number between 1 and 31, as 50 kech. / s, 25 kech. / s, 16.7 kech. / s and so on. When you specify a sampling clock DAQmx not taking in charge, he is forced to the top supported next, which in this case is 50 kech. / s. (you can read back the SampClk.Rate property to see what DAQmx forced the rate to.) For 44.1 kHz audio to USB-9229, you will need to re - sample the acquired data (which are specific to the programming environment).

  Assuming that you're just trying to do it for learning or experimentation, here are a few ideas:

  • Is the line connector configured as an output line? Many mothers today have reassignables audio connectors.
  • The volume of the source (wave, CD, whatever) high enough?
  • On the graph, is scaling auto turned on? If you display data in a table instead, are the numbers exactly 0 or any close?
  • The output of the line works if you are connecting to another device that is designed to handle signals to line level?
  • If you connect a battery (AA, 9V, whatever) for the USB-9229 instead, read the Max supply voltage?

• There is no audio signal of chronology in PREL12 the .m2ts files

  Windows 7-64, first 12 items (64 and 32 - the same result)

  Panasonic SC - 920 X camcorder, recoding format 1920x50p + DD5.1

  1. If I just copy the files .mts from an SD card into the PC and import it into PREL then there no problem with audio. It is to play the preview and timeline window.

  But in this case, I have a problem with the long record - camcorder breaks large files.

  So I use the SD instead of the simple copy import.

  2. the import of the SD using PREL12 (Get media of-> cameras Flip, AVCHD,...). In this case I get at disk .mts files and no audio timeline with these files. But in all other programs, these files are played with audio.

  3. import the SD using Panasonic HDWriter program. In this case, I get .m2ts files (and some metadata files.). These files read normally (with audio) in any player and the program I have (WMP, MPC, Corel Video Studio Pro X 6 etc.). Except the chronology of the PREL12.

  There is no audio signal of PREL timeline. And at the same time there is audio of the preview in the same PREL window (after double clicking on the item in the active project)!

  There is no yellow bar above these clips. Project settings - 1980x50p PAL AVCHD

  How to get audio of time?

  dik07

  Something for you to try.

  The quick and very rough to solve this way...

  Expert workspace...

  Before you import your media into the project, set the predefined project manually to

  PAL

  AVCHD

  Full HD 1080i25 5.1 channels

  To manually set the project preset

  • Open the project in the workspace Expert and go to file menu/new project and change the settings.
  • In the settings, set the project preset to match the properties of the source media. OK to get out of there.
  • In the dialog box new project opens, rename the project and make sure you have a checkmark next to the "Force selected setting on this project." OK to get out of there.

  And then import your source files in the project by the different ways you have tried and found not to work for your application.

  If it works, then the real solution...

  Premiere Elements does not come with a preset project to PAL AVCHD AVCHD 1080 p 50 5.1 channels.

  But, you can create one for use if gross suggests you need a project that is pre-configured with 5.1 channels included in its description. Please see details

  RTA Premiere Elements troubleshooting: PE11: export a file 1080 p 50 or 1080 p 60 with Audio to 5.1 channels

  Let know us the results and then we can decide what then.

• Pavilion p - 7 1287 c: sending digital video and audio signal from p-7 HP 1287 to HD TV

  No HDMI output on the back of the computer. Ordered a KENIMBENI Pro VGA HDMI converter, VGA male to male VGA Cable and a cable of Y min stereo to 2 RCA.  Kanex output VGA to convert HDMI is HDMI to the HDMI connector on the back of the HDTV (Viera by Panasonic).  No signal on the TV.  This motherboard or video card takes by taking a digital audio and video signal and send it to the TV.  Obviously with the VGA of the monitor on the PC is turned off.

  Previously, I had a cable HDMI to DVI and I had to awkwardly move the image on the monitor of the PC to HDTV, but with no sound.  Should I return the material (Kanex VGA to HDMI converter and associated cables) at B & H so that I can always go back and get a refund.

  Look forward to some potential solutions, wish this PC has HDMI output, would probably make this process much easier.  First time on so I hope someone can help.

  Hello

  I have a portable PC Toshiba Qosmio G50 - 12 q with 640 GB HARD drive, and equipped with 4 GB of Ram saw the Completed window system upgraded to the version of service pack 2

  I connected the video camera Sony PC 115 to the PC via the I.Link IEEE 1394 cable while that I import a video to Window Movie Maker in order to save it.

  At the moment where it is reproduced in the form of Movie Maker, I see the video reproduced the video camera but don't feel no audio. Then when I'm done for import video I want and he always see in Movie Maker, the program reproduces regularly or video he recorded or the audio exactly I didn't think it was important while it.

  It ' is usually?

  Working group than in the phase of import that I would have to see and feel or the audio video. Task not is defective cable because when I see the video recording in Movie Maker I feel also the audio base, means that the audio has left the video camera, is entered into the PC via the I.Link recorded it.

  To the point, I can hear the audio in the phase of transfer / import video or any other audio device from the camera / video, I have to in case of change inside of Window Movie Maker or the window given some details of formulation considers also the I.Link Jack specifically?

  Or the cable is connected between the video camera and PC with purpose there details? Even if it seems to me have connected well it boom ' as I have said, l "audio is saved."

  Thanks and greetings

  I have Sony camcorder DCR-TRV520E and in the past, I recorded several movies on my laptop.
  I used the Ulead Movie studio application and everything was OK.

  10 minutes ago that I tested it with Windows Movie Maker (Vista) too. Here a few facts:
  -My cam Sony is recognized correctly
  -Started Windows Movie Maker and chose the option IMPORT > digital video camera
  -Traveled in the right folder
  -On the next stage of the single application started rewinding videotape
  -Importing video has begun only and when finished I checked it and the sound was there.

  Later I chose the option "publish on" > this computer and after 20 minutes it was all over.

  I just use the firewire cable. Nothing special.
  I really don't understand what's wrong there.

  East - the first time do you it?

• ProBook 6540 b: no audio signal through Displayport

  The Displayport video output on 6540 b does support audio? If so, how I would allow sound through displayport through the windows? I was not able to get sound to participate in one of my TVs that has DisplayPort inputs.

  Hello:

  It's possible this is the case.

  There are a few PCs that do not support audio out of the view port.

  I was hoping that it works.

  What would you say to the manage audio devices in the hardware and sound section in the control panel?

  You see two audio devices listed?

  The laptop speakers would be the IDT audio and if you see an Intel HD audio device, for the display port.

  The only suggestion I can offer would be to connect to a display port, select the Intel HD audio device in the window and see if it works.

  If you do not see the two audio devices listed there, so I doubt he's has supported audio out of the view port.

• EliteBook 8540w: no audio signal through DisplayPort

  I'm trying to connect my laptop to my TV through DisplayPort. I bought an adapter DisplayPort to HDMI cable. The image is fine, but no audio is coming through. I don't see TV as the device in the sound Panel, and I have only (not Intel) IDT audio control panel.

  Any ideas?

  Solved.

  It was in the latest versions of the NVidea driver. I uninstalled the driver and then installed the driver that was originally shipped with the laptop (Oct 2010 driver version). The TV came immediately as playback device and its working now.

• PowerBook G4 can not get the audio signal of the MacBook Air

  My MacBook Air (early 2014) have no audio input. I try to connect the audio output of my MacBook Air to the audio of my PowerBook G4, but it does detect any sounds when I play something on my MacBook Air. I tried the same thing with my iPhone 5 c and the PowerBook detects the sound of the iPhone. I know that there really large gap between the PowerBook G4 and MacBook Air but PowerBook should be able to detect the sound of the MacBook Air.

  If you plug in regular headphones for the MacBook Air, do you get sound in the headphones?
