Following the instructions in
https://help.ubuntu.com/community/HdaIntelSoundHowto
in section titled
"Update to the latest version of alsa"
I installed the lastest version of ALSA. I used the following configure command
./configure --with-debug=detect --with-cards=hda-intel
for maximum debug output.
>From the output, it became apparent that the since the hda-intel driver
>detects my sound hardware
as a STAC9200 (and not one of the other, higher numbered models), the only
parameter I can set for
mode= is ref, any other value is ignored. And for the two settings available
to me (i.e no setting or 'ref'),
neither worked.
So, the best I can figure is that the hda-intel driver does not support my
particular version of the hda-intel
hardware. I would escalate this to the ALSA developers, but unfortunately I no
longer have regular access
to that laptop.
By the way, I've attached the debug output from the latest ALSA driver (from
setting --with-debug=detect
above), for both cases of the mode= setting. the case where I did not set the
model, and the case where I
set it to 'ref', in the event that anyone finds it useful (the files are
debug.none and debug.ref respectively).
