Jackpot!

This time I did a rebuild at /sys/modules/sound (instead of at
sound/driver) using the ac97.c referenced above. I now have sound.

FWIW, OGAIN and PHOUT mixer knobs don't seem to have any effect. Only
Vol and PCM seem to do anything when playing MP3s and videos.

Thanks, Ariff, for your help on this.

Let me know it there is anything else you would like me to try out.
