Windows 7 Media Center Has No Live TV Sound after exit and restart

[thedokes]

I constantly have a problem using WMC Live TV. Upon an initial startup the sound is fine however after I exit WMC and attempt a restart I get no sound.
I can restore the Live TV sound only through rebooting the machine.
This sound problem only occurs in Live TV - all other WMC & computer sound functions continue to work.

I'm using Win7 64.
ATI PCI-e Tv Wonder card.
Asus onboard sound VIA High Def Audio.
All Drivers are updated.
I have tried reinstalling WMC.
and control panel sound options have been tested.

Any Ideas?.

It seems like you are facing an issue with Windows Media Center Live TV, specifically with the sound after initially exiting and trying to restart it. Since you've already tried updating drivers, reinstalling WMC, and testing control panel sound options, here are a few additional steps you can take to troubleshoot this problem:

Troubleshooting Steps for Sound Issue in Windows Media Center Live TV:​

1. Check Sound Settings:
   • Ensure that the correct audio output device is selected within Windows Media Center settings.
   []Restart Windows Audio Service:
   • Sometimes restarting the Windows Audio service can resolve sound issues. You can do this by:
     • Press Win + R, type services.msc, and press Enter.
     • Look for "Windows Audio" service, right-click on it, and select Restart.
   []Check Volume Mixer Settings:
   • Make sure the volume for the application is not muted or set to a low level in the Volume Mixer.
     • Right-click on the Volume icon in the system tray and select Open Volume Mixer.
   []Disable Exclusive Mode:
   • In the Sound settings, under the properties of your playback device, uncheck the "Allow applications to take exclusive control of this device" option.
   []Update Codecs and Drivers:
   • Ensure that your codecs are up-to-date and compatible with Windows 7. Update your audio and video drivers to the latest versions.
   []Test with a Different User Account:
   • Create a new user account on your computer and test Windows Media Center Live TV to check if the sound issue persists.
   []Check for Background Applications:
   • Background applications or programs could interfere with the sound settings. Close unnecessary programs before using Windows Media Center Live TV.
   []Check Event Viewer for Errors:
   • Look in Event Viewer for any related errors or warnings that might provide more information on what is causing the sound issue.
   []Contact Microsoft Support:
   • If the issue persists, reaching out to Microsoft Support for Windows 7 might provide more specific assistance tailored to your setup.

     Additional Notes:​

   • Should the issue persist after following these steps, it might be a compatibility issue between your sound card, video card, and Windows Media Center. In such cases, contacting the hardware manufacturers for support might also be beneficial. If you encounter any specific error messages or issues during these steps, providing that information could help narrow down the troubleshooting process further.
