Hello

Headphones doesn't cut front speakers.

Have tried adding this line to alsa-base.conf
options snd-hda-intel model=? enable=1 index=0
(alsa-info script ran with above line commented out)

Havent tried all available models for ALC888 but 3stack-dig and acer 
didn't change anything. acer-aspire gave no sound at all.

Ubuntu 10.04
Acer Aspire 7736ZG

New install, problem was there from first boot.

Regards,

Hans
