Yes, that's exactly what I did in /etc/modprobe.conf, but it doesn't
appear to be enough.

Running aplay [file.wav] gives me:

ALSA lib conf.c:1578:(snd_config_load1) _toplevel_:51:23:No such file or
directory
ALSA lib conf.c:2823:(snd_config_hook_load) /etc/alsa/cards/aliases.conf
may be old or corrupted: consider to remove or fix it
ALSA lib conf.c:2686:(snd_config_hooks_call) function
snd_config_hook_load returned error: No such file or directory
ALSA lib pcm.c:1959:(snd_pcm_open_conf) Invalid type for PCM default
definition (id: default, value: cards.pcm.default)
aplay: main:533: audio open error: Invalid argument

Whereas 'apaly -D hw:0,0' works like a charm. So, not sure where the
"invalid argument' is housed.


As you suggest, I've already switched things around in my
/etc/modprobe.conf as follows. The card/index number are as I want them.
The install had them reversed from this:

alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 1 >/dev/null 2>&1 || : ;
}; /sbin/modprobe -r --ignore-remove snd-intel8x0
options snd-hdsp index=1
remove snd-hdsp { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-hdsp
