Hey Phil,

There's no way to be out of line when trying to help :-) Thanks for the
thought but alsa doesn't even see the card at this point, for instance
alsamixer gives me:

root at sphinx ~]# alsamixer

alsamixer: function snd_ctl_open failed for default: No such device

and alsactl (pointed at the file I created with alsactl store running
under Fedora 7 Live CD) gives me:

[root at sphinx ~]# alsactl restore
alsactl: load_state:1236: No soundcards found...

Thanks for the attempt!

Regards,
Chuck
