Thank you for your effort.
I have done cat /proc/asound/card0/codec* but the output was rather large, so I have placed it inside a text file.

so I guess you were right, it uses 268. Whoops, after rechecking, alsamixer tells me 268. I am sorry for this inconvenience.

PS. I am sorry if I'm posting reply's wrong, they do not seem to appear in the same post. I think this is because of gmail, I'm not sure.

Hi Lars. I've done a bit more googling for your model of notebook, and seen a
few posts saying it's using ALC268, and by installing the latest alsa driver,
at least one person had got sound working.
Would you post the output of.
cat /proc/asound/card0/codec*
Just to verify that yours is using an ALC278. It's possible that as your
notebook is very new that Acer have changed the codec on the mobo again.
Also the output of.
cat /proc/asound/version
And the OS you are using, and latest kernel you have.
I see that the alsa driver 1.0.15 is just about to be released as stable, but
IIRC it is for kernel 2.6.23. I may have misread that though. 1.0.15 does
have patches for realtek codecs though.
Don't trim any of the previous stuff, as this is a bit of extra info.
Nigel.
btw. The output of amixer wouldn't do any harm, and will show what mixer
controls you have.
