[mythtv-users] sound suddenly not encoding

[mstrimel@comcast.net]

Hello,
My mythbox has been running great for several months now.  Suddenly, it is failing to encode sound and it also refuses to schedule new recordings.  

When I try to watch livetv, the backend log shows "strange error flushing buffer."  If I run mythbackend with the "-v all" option, the log shows a very long string as follws (not sure if this is an error or not):

I'm pretty certain it's not a sound card problem, because if I unmute line-in I can hear the appropriate sound a few seconds ahead of the video feed, and my old recordings play sound.  I uninstalled and re-installed lame and toggled many sound settings but it didn't seem to help.

I also have a problem where myth will not accept new recordings ... when I hit "save these settings," the guide says the show is "not recording."  Yet I can record from live tv by hitting "r", with no sound of course.

These problems seem to have cropped up at the same time but I'm not sure if they're related.  I have searched the newsgroup archives, saw some mentions of the "flushing buffer' error but no solutions.

Any ideas?
TIA
