Today, I discovered the sound of my laptop (Acer Aspire E1 532) not working anymore.

The sound settings say "Dummy Output", and

sudo aplay -l

returns

aplay: device_list:268: no soundcards found...

I have applied all the hints given here.

Is there another hint?

I saw that somebody has solved that sound problem by "rolling back" the kernel version.

I used

uname -r

giving me the kernel version. I removed that kernel version with:

sudo apt-get remove linux-image-3.13.0-46-generic

During the removal, I saw that a new DKMS sound driver was being installed. After rebooting, the sound worked! And

uname -r

now gives me

3.13.0-45-generic

as the kernel version.
