[mythtv-users] Sound cards playing musical chairs

[Phill Edwards]

I have 2 sound cards - 1 is on-board using module snd_intel8x0 on
/dev/dsp1 and the other is a PCI card using module snd_cmipci on
/dev/dsp0.

Most of the time this works fine. But then, usually when it's time to
record my favourite program, they remap themselves so that I get the
sound from the a different program on other tuner as the sound on my
recording. It seems that the allocation of module to /dev/dsp device
is random because one days it works, the next it doesn't.

I've asked this before here but not had much luck, so I'm hoping
someone can help me this time. There simply _must_ be a way of
stopping the sound cards swapping around like this.

I've noticed that this rarely, if ever, happens on 2.6.10-1.9_FC2
kernel, but happens a lot on 2.6.10-1.14_FC2.

Modprobe.conf sound section looks like this:
alias snd-card-1 snd-intel8x0
alias snd-card-0 snd-cmipci
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ;
}; /sbin/modprobe -r --ignore-remove snd-intel8x0
install snd-cmipci /sbin/modprobe --ignore-install snd-cmipci &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-cmipci { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-cmipci

In the MythTV Setup screens I associate tuner card 0 with /dev/dsp1
and /dev/mixer1, and tuner card 1 with /dev/dsp0 and /dev/mixer1. My
sound out is set to /dev/dsp1.

Can anyone please help me solve this as it's a RRPITA (right royal pain...)

Thanks,
Phill
