• Off headset device

  I accidentally disabled my helmet camera. I had my audio device manager open to the Manager of the helmet. There is a box that says "disable this device" and I checked it accidentally. I clicked on apply, then the box was empty except for a text saying 'the device you are configuring has been deleted' even when my headset was plugged. I tried reconnected several times and nothing. I looked everywhere in the device manager / his Manager/Control Panel for anything that would allow me to activate my headphones to work. Any ideas?

  Hi teenassassin,

  You can try the following steps and check if it works:

  1. open the control panel. (Classic view)

  NOTE: open the start menu and click on the menu button of the control panel.

  2. click on the audio icon.

  3. click on the recording tab.

  NOTE: this also works on the reading tab, but there are usually no hidden audio devices there.

  4. right click on an empty area and click Show disabled devices.

  5. you will now see the audio devices disabled with the arrow pointing down on them.

  NOTE: these audio devices may vary depending on the installed audio card or chip you have.

  6. right-click on each listed off audio device that you want to activate and click Activate.

  7. you will now see this when the audio devices are enabled.

  NOTE: you can now change the property settings on these audio devices in the way you want.

  8. click OK to close the sound window.

  Kind regards

• I have a problem with finding a PnP USB audio device when you search for available audio devices.

  Hello.

  I am building an application that can find a PnP USB audio device and play a tone if the device is connected. I am able to search audio devices using "Sound Device Info.vi" of the lvsound2.llb that comes with labview.

  The vi can find the USB device in good conditions, but there are problems - I'll try to describe 2 scenarios.

  1. the USB device is connected before 'Sound Device Info.vi' is called for the first time.

  In this case, the program can find the USB device. If I unplug it, the device disappears from the list of found audio devices. If I reconnect to the same USB port, it reappears in the list. It's all good.

  If I reconnect it however a new USB port, the device is not found. This is not good.

  2. the USB devices is not connected when 'Sound Device Info.vi' is called for the first time.

  "Sound Device Info.vi" is not able to find the device. Disconnect and reconnect does not make a difference.

  I'm under labview 2012 on windows 7.

  I am running the application as an exe to build.

  I call 'Sound Device Info.vi' as a 'call for reference"and the reference is closed between calls to the vi. I was hoping this would unload the dll used in "Sound Device Info.vi" and would solve the problem, but it didn't.

  Is there a way to reset the information usb labview during execution?

  Concerning

  Stephan.

  Hey Stephan.

  The sounds screws require a DLL located in:

  C:\Program Files (x 86) \National Instruments\LabVIEW 2012\resource\lvsound2.dll

  Internally, LabVIEW uses the DirectX API to enumerate devices. The one caveat is that probe us for devices when loading the DLL. We probe not later. So that it works for Bluetooth, USB, fire wire, etc. devices that can be inserted or removed at any time, you control somehow when this DLL charge and discharge. To do this, please see the following document:

  Dynamically that I can load and unload a DLL in LabVIEW?

• Windows does not recognize tv as audio device after it has been turned off and turned back on.

  I have my computer hooked up to a HD TV with the HDMI cable.  The sound also pretended on television.  The HDMI cable is connected to my Radeon HD 6950.  I use Realtek HD Audio Manager with the ATI HMDI default Audio device.  All records are up-to-date.

  When I put my TV off and leave the computer running, I go back and turn on the TV and the computer behaves as the TV is not plugged, but only for audio.  The video is still there.  In the audio playback window, I noticed that Windows would go to the optical audio device, even though there is nothing plugged into this Jack.  I disabled all other devices and left only the HDMI device, so it will not move on.  Now when I turn on the TV it is just like nothing is plugged in at all for the audio.
  Any help is greatly appreciated!

  Hello
   
  1. What is the brand and model of your computer?
   
  2. which edition of Windows are you running?
   
  Example: Windows 7 Professional 32 bit.
   
  It could also be a possibility that a manual entry is required from your TV to the HDMI connection, please check your Menu\setting where the HDMI and PC connection is checked once it is connected to options to switch the Audio and TV screens.
   
  Please follow the steps mentioned below to help solve the problem.
   
  To disable improvements audio speaker

  b. on the playback tab, click speakers, and then click Properties.
   
  c. click the enhancements tab and then select the check box turn off all the improvements .
   
  If you do not see the enhancements tab in the speakers Properties dialog box, these features are not available for your speakers, and this procedure is not applicable to your computer.
   
  If disabling audio enhancements solves the audio problem you are having, this indicates usually that your audio driver needs to be updated.

• I can't change "sounds and audio devices" in the Panel

  original title: I can't change "sounds and audio devices" in the control panel after the update my card NVIDIA vidio driver and Microsoft DirectX in my Windows XP SP3 update.  How can I fix it?

  I recently updated my card (NVIDIA GeForce 6800 GT) video driver and Microsoft DirectX after you have experienced a problem with a casual game.  That fixed the problem, but then I noticed that my sound 'e-mail notification' had failed in its original supplied with Windows.  I changed "Sounds and Audio devices", registered, registered as a new regime, etc., and still plays the old default Windows sound.  It was the only noise I had on Windows.  When I check "Sounds and Audio devices", the sound, I have chosen is the one listed, and it does not play when I check, but when the mail arrives, I hear the old Windows by default.  I don't know if the updates, to happen or not, caused only that it took place at the same time.  Thanks for any help you can give.

  Thank you for your suggestions.  It turns out that my e-mail client, "Eudora", had somehow reset the default mode in the Windows sounds.  I forgot that there is a choice to "Be careful" in Eudora Tools.  After I changed it back, it worked perfectly.  Once again, thank you to answer me.

• Change the default audio device and the recognition of the application

  I'm new to Vista (home premium w/sp2) and I am confused by works the assignment of default device (control_panel-> sounds), specifically the device change with existing applications (running).

  I change frequently between the speakers and the headphones - however, the change of output device is not recognized by running applications, such as iTunes or Firefox and will not be recognized until I have completely quit and restart the application.

  Why?  It is extremely annoying and incoherent other well educated such as Mac OS X platforms.  I would just like to change the default audio output device, on the fly, without the need to restart applications.

  I do something wrong or Vista offers this functionality to the end user?

  Thank you!

  Hello Wyntr,

  Thank you for using the Microsoft answers Forum.

  Currently, the function of switching between audio output devices is carried out manually. To make the selection, you can click the sound icon in the taskbar, then click the button at the bottom of the volume control Mixer. In the properties of the volume, you can click on devices in the upper left corner and select the appropriate device to make it the default for applications open from then on.

  Let us know if this can help, or if you have additional questions on this subject.

• BlackBerry Q5 display on lock screen wallpaper will not change (with aprental controls off-road and without)

  The following took place in my quest to solve the meanless screen too high.  That's why I serched for several Blackberry World and internet screen savers.

  At some point, I downloaded a wallpaper of the internet where I have the image itself has been doenloaded in images and from there I clicked it and got options to use as paper screen wallpaper and wall of a lock.

  Later, I found the other wallpaers and succeeded him.  However, it has not changed the lock screen wallpaper.

  I did it with the parental control is turned off.  Later, when I changed the wallpaper that's not going away from the lock screen, the icons were changed and new wallpaper was left out leaving a black background.

  But this process has not changed the lock screen.

  I deleted the uploaded image independent of photos and the lock screen still shows the wallpaper I'm changing.

  Any suggestions?

  Thanks, I've thought about it.  It's the fact that the original file was set as wallpaper screen and lock of bot.  I changed just walpapers thanks walpaper software added to the Q5.

  Someone knows how to fix this?

  Hello, DuFF1

  You can have only one default device.

  It is not possible to put two devices by default, nor is it possible to configure the output in default Media Center device. You can try searching for additional Media Center change the audio device by default or continue editing the device default manually before watching TV on the Internet.

• Audio device not working not because I changed the OS from WIN XP to WIN 7 but the I have the sound card!

  I have a sound card on my system and it worked correctly with windows xp... but few days back when I changed my OS to WINDOWS 7, the audio device no longer works! his watch the following message on roubleshooting 'No Audio Device Installed "! I checked for drivers, but couldn't find them on the net! I also tried to find them through the updates windows automatic update, but still not recovered the problem! What should I do? Please suggest me a solution!

  If you have a real soundcard as appositive to an audio chip on the motherboard, all win7 drivers would get this site of sound card manufacturers.

  However since win7 cannot find/install any audio driver by default I think this card is not supported under win7.

  I guess you do not have to use the win7 Upgrade Advisor, before installing win7, which would show any material not supported

  [Moved the Forum of the SOUL of the After Effects - MOD forum]

  Hmmm.  It's very strange.  For the experience, I tried to disconnect a sound card, while the SOUL is coding.  I get the message dialog box, but the encoding continues without stopping.  Eventually, this may be specific to certain sound cards.  What is your sound card that you have on your computer?

  For a workaround, could you try checking the "do not show again" checkbox in the message dialog box next time you see it?  Then, click no you should not see this message again and I hope that this problem would disappear.

  You can synchronize the music upwards to 1/48000 second for still or video images.
