[mythtv-users] UNCLE! I give up... No audio from BT878 card.

[Richard Shaw]

It's official. I give up. I've tried everyting I could find googling for 
BT878, bttv, snd_bt87x.

It looks like the system is identifing the card correctly as card type 
40 and tuner 2. Video works great. but nothing I have tired has gotten 
me an entry for /dev/dsp /dev/snd/pcm1 or whatever (0 is my sound card) 
or cat /proc/asound/cards (other than my sound card). Here is the 
relevant info from dmesg

Any help would be greatly appreciated. I don't have the btaudio module 
available, and I don't want to us OSS anyway. I've read somewhere that 
the bt878 driver is an OSS driver but if I try to do a modprobe -r bt878 
it unloads everything including bttv as well. snd_bt87x looks like the 
right module but I haven't gotten it to work even with adding it do 
modprobe.conf with "load_all=1" which someone suggested.

My next step is to save up for a Hauppage card...

Thanks,
Richard
