Comment (by nasevz@…):

 I tried enabling "Do not adjust volume" but it did not solve the problem.
 [[BR]]
 There is a cable which connects "audio out" from TV card and "audio in" of
 the sound card. To eliminate tuner as source of the problem, I inserted
 external audio source to "audio in" of the sound card and started live tv.
 The problem appeared again. When I changed recording source in system
 sound settings form "line in" to "mic" and back again to "line in", while
 live tv was playing, sound appeared, but only until next channel change.
 I will mention again that if mythbackend is started manually with
 following command, the problem with sound disappears.
 {{{
 sudo mythbackend -l Mythbackend.log -v record,playback
 }}}
 My guess is that this is some timing problem and little time that is spent
 for writing log file requested by the command, slows down mythbackend
 which solves it.

 In my previous post I wrote that I changed sample rate to 48000, but the
 problem was not solved.
