Could we have an update on this please?  Do these problems persist in
2.6.12-rc5 and/or 2.6.12-rc5-mm1?

Thanks.

You are using alsamixer and not some GUI mixer, right?  There were

These are harmless, it's just telling you that because control #42 was
renamed from "Surround Jack as Input" to "Surround Jack Mode".  Looks
like it was changed from a boolean to an enumerated control.

Finally I got it. There was a buglet in original patch. Working patch follows.
Verified in... just my box (intel onboard sound). Against rc5-mm1.
