I tried the model=auto option, too. It works mostly, but the mixer node
seems to not be utilized correctly/at all. The capture source list does
not contain "mixer" anymore, and there are no playback controls for
Internal Mic/Mic/Line. The Capture setup seems to be built correctly
(except for the missing mixer). The auto setup adds two extra input
devices for jack sense.

alsa-info for the revised patch-set (mailed soon) with and without
model=auto is attached. Information I consider irrelevant (non-sound
modules and dmesg context not relating to sound) has been edited out.

BTW: I seem to have encountered an ALSA user-space bug: The codec
provides a "master capture switch", i.e. the "mute" of the adc in amp.
It also provides a "capture source selection enum", i.e. the "Connection
Select" of the adc widget. The enum provides mutually exclusive capture
sources that have no volume control, whilst the master capture switch is
coupled with the capture volume control, and should not be related to
the source enumeration. But if I play around with capture sources in
alsamixer, the "Capture Switch" is turned off as soon as I switch the
source from the first item in the Mux list to something else.

This happens with both the patched hard-coded "BenQ" configuration and
the auto configuration.
