[mythtv] ALSA "fixes" actually break stuff in CVS?

[M. S.]

Hi -

   I'm not a developer, so it's nearly impossible for me to troubleshoot by 
looking at the source, but I was running a version of CVS in October, and 
last night I updated my CVS and now I'm having massive sound failures that 
cause Myth to be totally unusable.

  First, without changing any of the previous settings, I went to watch Live 
TV and I got a message saying that /dev/mixer wasn't a valid device and 
couln't be accessed.  After a little research on the dev mailing list 
archives I see that it said to put "default" as the mixer device.  I also 
use software-dmix settings and an .asoundrc file so it uses digital audio.

  Second, and this is the problem that basically makes Myth unusable, is 
that after about 20-30 seconds of watching TV... I get WriteAudio: buffer 
underrrun errors repeatidly until I exit to the main menu.  This causes the 
video and audio to go into a slow motion convulsion.  I have submitted a bug 
report because it had worked in all previous versions of myth since .15 just 
fine.  I also reinstalled ALSA just in case and update from 1.07RC2 to the 
latest release of 1.07 to verify it wasn't something wrong with that.

  Unfortuantly, there is (was) an overwhelming amount of reasons I used CVS 
over .16 (functionality, features, and fixes).  I know that a lot of work 
went into supposidly "fixing" ALSA in the current CVS, but I don't really 
think it has fixed much besides breaking Myth.  I'm not even sure how to 
troubleshoot or fix this problem at this point.  Anyone have any ideas?
