Title:
[Macmini5,3, Cirrus Logic CS4206, Headphone Out, No sound at all
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
After a fresh install there was no sound at all. I added the line
options snd-hda-intel model=mbp55
to alsa-base.conf, now there is sound but only through the internal speaker,
while in Sound Settings only 'Analog Headphones' appears. The same with
model=imac27. With model=auto in Sound Settings both the speaker and the
headphones appear (looks like everything is ok), but in that case there is no
sound at all.
