As a follow-up to this thread, I've mostly given up on this. The
occasional time when MythTV playback would start while "aplay" was
playing a few seconds of silence was annoying.<br>
<br>
I tried to add a MythTV System Event Handler, to do "pkill aplay"
when playback starts, but that didn't seem to work. I didn't really
look into why. It may be that the pkill itself didn't work, or that
it was taking too long to pkill the process, and the sound device
was still in use by the time MythTV playback started. In any case,
the whole thing seemed clunky.<br>
<br>
One more thing, I reported earlier that when I had an HDMI cable
from my HTPC to the soundbar, and another HDMI cable out from the
soundbar into the TV (so using the soundbar as an HDMI switcher as
well as speakers), I had to add 350ms of audio delay to MythTV,
otherwise sound would come out before the pictures. I have
experimented some more and although that is the case, any other HDMI
source I've tried (Roku, PS3, Xbox 360) does not have this problem.
If I plug my HTPC directly into the TV I don't have any problem
either.<br>
<br>
I can't work out why MythTV would act differently when played
"through" the soundbar like that. Anyone have any ideas? I'm using
Intel graphics if it makes a difference. I haven't done any more
tests like using VLC, or looked in frontend logs.<br>
