This 'hw=1.0' snippet above seems interesting: Do you have a
'/etc/asound.names' installed? I'm not sure if this file is still
necessary with today's snd_aoa* drivers, but I'd give it a try in case
things don't work as expected. Here's a bit more on it, search for
'asound.names' on that page:

http://www.thinkwiki.org/wiki/Installing_Ubuntu_6.10_(Edgy_Eft)_on_a_ThinkPad_T60

I attach my own 'asound.names' file. I wouldn't recommend installing it,
because I'm not sure we have the same sound hardware ... Anyway: if
you have the file installed I'd recommend backing it up before
changing it ....

Just in case: this is what the attached file seems to be working on
relatively flawlessly, AFAIKS:

$ cat /proc/cpuinfo

Good luck!
