[mythtv] No sound using btaudio and 2 tvcards

I'm hoping someone can help me or point me in the right direction.


I am currently running on mythtv-cvs as of about Jan 26th.  I have
two Happauge WinTV cards and am using the btaudio driver.  I have
alsa installed the the ens1371 driver and sound is working fine.
I have use aplay to send sound to the speakers and it played fine.
I have even used sox -c 2 -w -r 32000 -t ossdsp /dev/dsp2 -t ossdsp /dev/dsp
to listen to the analog tv audio. (sound bad but it works.)
I only have one tvcard configured in mythtv at the moment.

When I watch live tv I cannot hear any sound using the digital
dsp device on btaudio.  When I try and exit back to mythfrontend
the screen locks up and I have the Alt+Ctl+Backspace to kill X and
restart.  When I use the analog dsp device my sound plays at the 
wrong speed.  I've tried different combinations of settings using
the setup program with no luck.

Now the really strange part... all this has been working before.
I have used the digital dsp and both the audio and video played
beautifully.  There were no lockup problem when changing channels
or exiting live tv.  I don't know what I did to get things this
way.  One reboot later and everything is FUBAR again.

Any Ideas?
