Public bug reported:
This is a freshly-installed Precise (from beta2 iso) on an AMD64 custom
built computer; the motherboard is an ASRock N68-GE3 UCC, as you can see
from the files the chipsets are all NVIDIA. The audio codec is VIA.
Main problem: alsa and pulse's idea of switching between the speakers
and headset is wrong. If I open alsamixer and toggle the (problematic, I
heard) “Independent HP” switch, that works like a charm; turn it on and
I get sound only on the speakers, turn it off and I get sound only on
the headset. But nothing else (jack sense, clicking an output on Sound
Settings, even muting “Front” by hand) works.
Secondary problem: once that's working, it would be nice if jack sensing
would do it automatically.
I tried playing with the “model” flag and even “sense_mask”, but nothing
works. I currently reset my alsa-base.conf to factory.
I read many reports telling me to install the latest from ubuntu-audio-
dev, but of course there aren't any for precise yet.
Also installed some hda stuff from diwic; hda-jack-retask reports my
front pin is a green headphones front pin as it's supposed to be, so I
didn't override anything. And hda-jack-sense-test calls it “Green HP
Out”; but only lists it with -a.
