I've been testing the first version of your patch on an HP 6510b, since
the 12th of January.

So far I haven't encountered any regressions. There are however some small
issues that also are present with the old driver.

I have the following selection of recording devices:
Mixer line     is currently set to   0:0
Mixer mic      is currently set to   0:0
Mixer monitor  is currently set to   0:0

To record from the microphone, I have to use the monitor device:
Recording source: monitor

Physically neither the notebook nor the docking station have a line
in socket. Of course such a thing might simply be on board and NC.

Setting a volume for line, mic or monitor has no effect. To hear the
microphone on my speakers/headphones I have to use igain instead.
Igain sets the microphone volume independent of the recording source.

There's also ogain, which doesn't seem to do anything either.

What I expect is that the recording source for the microphone was
mic and that the monitor recording source could be used to record
the cumulative output of all channels.
