[mythtv-users] Changing channels gets no sound until I switch audiotracks

I had a problem with sound stopping after changing from a stream with AC3 to
one that was not. I came across the solution when trying to fix something
else. The fix I used was to change the mode from PS to TS. You can get
details on how to do that here:


All recordings should have all the audio tracks. If your problem is the same
as mine, the sound will always work when you watch a recording anyway (since
the channel doesn't change).

Hope that helps,
