[mythtv-users] Problems with sound when using 2 cards of the same type

[Timothy E. Krantz]

Hi,
while I know this is not strictly a mythtv question I was wondering if
someone here might be able to help.
 
I have a MythDora 5 box that I put 2 Pinnacle PCTV HD (800i) cards into and
have since been having problems with sound.
 
Here is the relevant portion of the dmesg output:

Notice in particular:

Here is the section of modprobe.conf file related to sound:
 
options snd cards_limit=4
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/
modprobe -r --ignore-remove snd-intel8x0
alias snd-card-1 cx88_alsa
options snd-card-1 index=1
options cx88_alsa index=1
remove cx88_alsa { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/mod
probe -r --ignore-remove cx88_alsa
alias snd-card-2 cx88_alsa
options snd-card-2 index=2
options cx88_alsa index=2
remove cx88_alsa { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/mod
probe -r --ignore-remove cx88_alsa
 
Basically with the Intel8x0 failing to load I get no sound at all out of the
box.  If I remove either of the cards things work ok.
 
Any ideas greatly appreciated....
