[mythtv] [Committed] Your soundcard is not reporting free space correctly.]

This patch seemed to fix a problem for me that someone else had too.  I had a recording that played fine in mplayer, but in mythtv it would start with no sound.  Skipping around in the file sometimes brought the sound back.  After the most recent CVS update it plays the file fine.

The file was recorded Mar 28th with a fairly recent CVS build, and I'd never had that problem before with many months of MythTV usage.
