I get the same error after my computer crashes, and nothing plays, and
my sound card doesnt show up in my mixer, but I have the exact same
chipset, I am wondering if I slapped one my cheap pci audio cards in
would it fix it, because it throws off my sound card assignments, and
I end up with my first tuner recording from my second tuners audio,
then my second tuner recording no audio at all

Please go into the TV Settings, Recording Profiles and
setup the four 'Software Encoders' profiles.
Assuming RTjpeg for now.

Mmmm... Not sure what's causing this... Maybe have a look where it suggests?

Well, if you read the error message, it thinks something's using your 
sound card ;)

Only one thing can access the 'raw' sound device at once.
fuser /dev/snd/pcmC0D1p
will give you the PID of the process that has the sound device already 
open. You can look this up in
ps aux
, to find out what the process is, then track it down in your init 
scripts and kill it.

Cheers,
Allan.
