[mythtv-users] Crackly sound and large mythfrontend log

[Matt Rude]

I'm having a problem with bad 'crackly' sound coming from my soundcard.  
So I went to look at the log and found that the log file was 15Gb once 
looking at it I am seeing alot of what you see below "AO: Broadcasting 
free space avail" and "AO: audio waiting for buffer to fill: have 2048 
want 4096".   My main question is what is this telling me? I think it's 
clear that I have a soundcard problem but I have to idea where to start 
looking to fix this problem.

This is a 3Ghz system running the SVN head from today.
