[mythtv-users] sound goes away when changing channels

[Neil]

Hi everyone, 

I installed the latest cvs version yesterday. I only have Air2pc capture 
card. When watching the first channel that comes up when I press 
WatchTV(livetv), the sound is ok. Once I select another channel, picture 
gets displayed but no sound. I quit livetv and select it again. The last 
channel now gets a sound. What is the fix for this? 

Any help will be greatly appreciated. 

Thanks. 

Neil
