Sound stopped working

Few days ago sound stopped working at office PC. It may be related with kernel update but I am not sure. Output of some commands:

$ lspci | grep Audio

If you need more info, please let me know. Any help is appreciated.

Re: Sound stopped working

Downgrading to kernel26 2.6.38.2 might solve the problem.

Re: Sound stopped working

I have been having different sound issues; I get output but no input. Information: the problem is, this has been going on for quite some time here. I think since a couple at least KDE versions back; the problem mostly has been with the libnotify update. Can't recall for sure which kernel update it was at the time.

:) pacman -Q kernel26
kernel26 2.6.38.4-1

And, I don't hear anything at all when I run this, yet it's acting like it's playing just fine:

:) aplay -D front /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

:) aplay -D front /usr/share/sounds/alsa/Front_Center.wav

(I tried twice) - Yet it does play, and I hear it if I just go to it in nautilus and just mouseover it.
