[mythtv] dual tv cards - modules.conf

Ok, I guess I had a lot more to learn about gdb...

Here is the output of bt:

#0  0x409e0fe1 in nanosleep () from /lib/libc.so.6

#5  0x40760bff in pthread_start_thread_event () from

And here is "info threads":

I was trying to look at how I can get the two sound cards
running correctly and found some info on how there are some
problems with devfs and alsa - I get the following in dmesg:

devfs_register(unknown): could not append to parent, err: -17

and end up with only one dsp entry in /dev/sound plus an
'unknown'.

Isaac, could you please explain briefly how you have your
sound working (btaudio etc.). I appreciate the help so far.
