Im using Mythtv with an AverMedia TV98 (BT878). Whenever MythTV finishes a recording or whenever I back out of watching Live tv the sound keeps coming out. I cannout get rid of the sound without killing MythTV and starting it back up. Any ideas? I have a sound cable running from the Tv Tuner sound out to the Sound in on my Sound Blaster Live!. Any help would be appreciated.
