How to switch sound-drivers, and to which? [AMD] Hudson Azalia Controller
- by Anders Martini
System settings/sound does not open, freezes and I have to force close. Speaker symbol with volume control does not open scroll-down menu, and there is no sounds. Many people have problems with Hudson Azalia in Ubuntu, but I found no working solution.
I don't really understand much of this, but here are some more details:
aplay -l :

(after running this one, it starts some kind of process that doesn't get any results, and doesn't stop, terminal has to be shut down)
lspci -vnn | grep -iA5 audio:

It seems to me that I'm currently running hda Intel drivers on my AMD Hudson Azalia soundcard. I can't see what drivers this soundcard uses.
Do I need any additional drivers for my soundcard, and where would I find them?
