Tallima: I got it fixed! After a fresh install (this time with /home on a separate partition!),I don't know which kernel makes it work, but I used the newest Kernel, rebooted, and it detected it. Now i have sound. Thanks guys!
good you got it fixed. sometimes with mint, you just need to shutdown and turn it on again. restart doesn't seem to work, and you will have sound again.
i experienced the same issue with both mint 17.2 and kubuntu 15.04.
the solution was on a five year old forum post and the person didn't know why this worked either.
im not sure if you have already tried this but if this happens again ctrl + alt + backspace, then login again. if that fails do the shutdown thing.
something else to try before making another re-install
