Thanks for the hints and the applet... after some meddling around I
found the magic incantations to fire up the amp / speakers on this
laptop are to force model=acer-aspire in /etc/modprobe.conf, then using
the applet from the URL quoted above:
./hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2
I confirmed stereo operation... it doesn't react to headphone
insertion, plays audio through speakers and headphone jack in that case.
Didn't try 5.1 (this laptop has a 5.1 speaker set) yet but I
wouldn't be surprised if that was trouble too. Still this is waaaay
better than silence! Thanks again for the help.
