#TV Cards 
#This is the standard alias line for bttv not sure meaning 
alias char-major-81 bttv 

#Pass option to bttv module to enable debug logging 
options bttv debug=2 


#OK here's the fun one. We need to enable btaudio, but we want to 
#pass some options to keep it efficient. debug=2 means log debug 
#information. digital=1 means enable the digital dsp channel. 
#analog=0 means don't enable the analog channels. Rate=32000 
#means tie the sampling rate on the card to 32000 for the dsp on the 
#tv card. This is important to do on the Hauppauge cards. 
#!!!! Important for 2 tuner cards -- the optional btaudio argument of 
# dsp1=1, dsp2=2, mixer1=1, may work for one card, but it sure 
doesn't 
# for two tuner cards. When I continued the expression for dsp3=3, 
# etc, the module wouldn't load. The only way to get it working was 
# to pre-load the alsamixer module and let it take /dev/dsp0. Then 
# btaudio will automatically take the next 2 or 4 /dev/dsp1 -- 
# /dev/dsp4 depending on if you've enabled the analog outs or just 
# the digital ones. 
options btaudio debug=2 digital=1 analog=0 rate=32000. 

# This is the most important line. This tells the btaudio module 
# to load only after the snd-pcm-oss module has taken over the 
# /dev/dsp0 device slot. This line was the key. 
pre-install btaudio modprobe snd-pcm-oss 

# This line makes sure btaudio is loaded before bttv. Not sure if or 
# why this is important, but it works for me. 
post-install btaudio modprobe bttv 

# Couldn't get it to work unless I tied the sound-slots to the 
# btaudio module. Not sure why here.
