Some strange audio-related (as far as I can tell) issues - possibly 2 different ones:
http://xbmclogs.com/show.php?id=144512
first play (movie 1) worked perfectly, with sound.
2nd play (movie 2) was playing at about 8 fps, chopping, and no audio.
3rd play (movie 1) works fine.
4th played fine(movie 3) works fine - pass-through audio
5th play (movie 2) 8fps issue
6th play (movie 1) 8fps issue
7th (movie 4) pass through audio - work fine
8th (movie 1) works fine
9th (movie 2) works fine
10th (movie 4)- it all goes really bad here. It can't create the audio stream and proceeds to play the movie as fast as it can without the audio to sync it, spitting errors the entire time. At this point the audio system has 'crashed' for ALL audio playback, passthrough or analog, and I have to restart xbmc to get it back.
Curiously the issue on play #10 only seems to happen if I leave it sit for a while and play a passthrough audio movie. It might be related to the keep audio alive thing, but it has to sit for longer than 1min (as it did on play 7), so I doubt it.
Audio on the menu system (ticks etc) between movies is also very intermittent - sometimes it works, sometimes nothing at all.
I've tried the different 'keep audio device alive' options and they don't seem to matter at all on any of the issues. I've also tried the 'optimized' vs 'best match' to no difference.
As long as I've got that log file posted too - here's what happens on the video side of things when I play that 3d movie (movie 4):
It's all squished horizontally, yet when I take a screenshot it's
the right AR with side black bars - and curiously doesn't show the 3d anaglyph effect (though I'm guessing that's intentional?)
I would guess this has something to do with scaling, because the video is 1920x2160
EDIT: After upgrading to 13.10 (still with no pulseaudio - just updated alsa I guess) it looks like the 8fps issue is fixed, but the failure on #10, UI audio intermittentcy, and 3d thing is still happening.
edit2: I did try with pulseaudio in 13.10 for a bit and it seemed to fix all audio issues (though pulse itself seems to have an issue with passthrough audio/5.1 on my setup that I haven't looked at yet - probably just some settings) so.. one possible solution here might be 'install pulseaudio' which is an interesting change of things.
