Early indications here are that updating the ALSA drivers fixes the problem. I've usually noticed the problem when coming in to work and the machine has been suspended, I did that whole thing now and reconnected external display + headphones and I got proper sound. Seems promising.

Playback to headphones is just fine. If I switch output to one of my monitor, connected by HDMI, the soudn comes out there, but with half speed. That sounds kinda funny, but weird and not as it should. Maybe it is somehow related to suspend mode as it was fine a few days ago (after a reboot? Can't reboot now to test, sorry). I already tried sudo /sbin/alsa force-reload but that didn't do anything.
