Well, I got no response, but have isolated this problem further, and am
more convinced it has to do with MythTV. I have rebuilt MythTV against a
few ALSA (1.05, 1.06, 1.07, and 1.08) and ivtv (0.2.0-rc3 and 0.3.2)
versions. I wish I could be more clear, but here's the behavior I
observe. Sometimes (I can't see why it's not always since I record
everything with the same settings) when I play a recording sound
disappears. This can be either when I go via media library or as above,
when I watch while recording. As above, sound is dead for all apps and
users on my system. However, if I play a small MPEG with mplayer
outside MythTV it seems to reset the sound.
I am configured to use ALSA:default for sound out.
Does this prod any further thoughts?
I wonder if the recent sound codebase updates have done something to the
init/deinit of the sound code?
