No sound, pavucontrol only shows "dummy output". aplay gives nothing, lspci shows soundcard:

04:01.0 Audio device: VIA Technologies, Inc. VT8237A/VT8251 HDA Controller
    Subsystem: Micro-Star International Co., Ltd. [MSI] Device 7318
    Flags: fast devsel, IRQ 17
    Memory at dfafc000 (32-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>

Didn't find any solution around the web. what can I do?

seems to be a bug in the kernel with my sound card: bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1265611 –  chagui Jun 1 at 10:52

This worked for me:

    rm -r ~/.config/pulse
    pulseaudio --kill

I also logged out and in in-between these two commands, but the pulseaudio --kill did it for me.

Oh and finally I also had to run pavucontrol and meddle with the output choices once or twice:

    pavucontrol

I switched from 'Speakers' to 'Analogue Output', and then back to 'Speakers'. Then, I got sound!

I got the ideas from this thread: http://ubuntuforums.org/showthread.php?t=2211608&page=2&highlight=trusty+sound

Good luck

This alone did not work for me, but the provided link and some tinkering around did. First I had to use aplay -L to find what devices I had, then aplay -D sysdefault <somefile> to verify that I get a sound in this case, then I've updated ~/.pulse/<somehash>-default-sink to point at that device and finally - logout -> login. –  Uri Barenholz Apr 27 at 7:19
    
laher, unfortunately this doesn't solve my problem, pavucontrol still shows nothing. --- Uri Barenholz: As I said, aplay doesn't show anything in my case. –  chagui Jun 1 at 10:46
