Still a problem for me, on Acer Aspire 5050 with Ubuntu Jaunty 9.04,
after trying a bunch of values for model= . '
Basically, with the best profile I found I was able to independently
control and mute speaker and headphone volume, but none detected the
headphones (manual muting was required). What's particularly annoying is
that acer-aspire profile actually DIDN'T work on my Acer Aspire...
Some test results:
targa-dig - Speakers don't mute when headphones are plugged in.
tagra-2ch-dig - can't get speakers to work. Headphones work.
acer-aspire - The Headphone switch DOES work. Speakers DON'T work.
acer, 6stack-dig - Speakers on Surround channel, headphones on Front.
Either can be independently muted, but only manually (no automatic speaker
muting). Headphone switch doesn't work.
3stack - can't get speakers to work. Headphones switch doesn't work. Headphones
do work.
3stack-dig - speakers work, but don't mute with headphones plugged in.
Headphones work.
