I was testing my sound settings when suddenly, nothing worked anymore. I tried looking for a way to reset it without having to restart my session but all the current solutions point to /etc/init.d/alsa-utils restart which seem to be missing from my system.
Audio is now handled by PulseAudio in 10.10 so what I did was:
pulseaudio --kill && pulseaudio --start
and it worked for me. 
Thank you, that worked perfectly!

Thanks, that worked great — only thing is to quit the applications using sound and then relaunch them (Firefox, Rhythmbox in my case).

When the audio stops working, can you try relaunching it via command line using:
padsp (insert command here)In the case of chrome, it would look like:
padsp google-chromerystraum
