Thanks. I'm beginning to get the picture.
This machine has the Intel sound device and
one USB adapter. I've adapted the example
to this.
============
alias snd-card-0 snd_intel8x0
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 snd-usb-audio
options snd-usb-audio index=1
remove snd-usb-audio { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-usb-audio
============
The example lacked the "remove snd-usb-audio ..." line;
presumeably it is as necessary as "remove snd_intel8x0 ...".
lsmod also reports snd_hda_intel. The device
index isn't influenced by this module?
Appears that ALSA identifies a device by an
index analogous to eth0, eth1, ... . These
instructions to modprobe impose that snd_intel8x0
is always 0 and snd-usb-audio is always 1.
What if there are two Intel devices and one USB?
Thanks, ... Peter E.
