Comment 8 for bug 220006

I've come up with a non-ideal fix for my problem. I found out that what is really going on is that ubuntu is mixing up my headphone jack and speaker outputs.

With "options snd-hda-intel model=auto" set in /etc/modprobe.d/alsa-base:
    When I plug my headphones into the headphone jack, it believes it to be the speakers and is already outputting sound. Laptop speakers do not function even when switches in the volume control are toggled. <-----Thus headphone only sound

With "options snd-hda-intel model=arima" set in /etc/modprobe.d/alsa-base:
    When I plug headphones into the headphone jack nothing happens. When I toggle Headphone switch to 'checked' in volume control, playback can be heard from laptop speakers! If I uncheck it, I can still get headphone sound from the "Front" output jack as this would always be on anyhow.
    When I toggle the headphone switch, I can see in alsamixergui the mute toggles going on and off for the headphone channel. It is not possible to toggle the mute for the PCM channel. Volume is controlled by using the PCM, Front, or Master sliders; Headphone sliders are nonexistant.

I can also use "options snd-hda-intel model=targa" instead of armia to acheive the same results. as far as I can tell, the other model options do the same as 'auto'.

Any ideas?
