Subject: [mythtv-users] Problems with sound when using 2 cards of the
sametype


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....

sorry to  reply to my own post but changing my modprobe.conf to the
following seens to have fixed things:
 
options snd cards_limit=4
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/
modprobe -r --ignore-remove snd-intel8x0
options cx88_alsa index=1,2
