OK, thanks. I've had a brief look at this here but so far as I can tell
I'm not able to see these problems on my system. I am using a
completely different machine, though, with different hardware and I
haven't checked through your configuration in detail. I'll have a more
detailed look early next week.

One other thing that would be useful would be to put trace which logs
the register writes in ac97_write() in the driver and then try testing
both using alsamixer and then amixer to do the final enable of the
Speaker Mixer PCM Playback Switch.
