I upgraded my HP Mini from openSUSE 11.2 to 12.1. Everything went smoothly; I have discovered just one problem so far: when shutting the computer down, it emits a crackling sound for 1-2 seconds. I spent several hours googling for solutions and trying them.
The only working solution I have found so far is adding the following line to /etc/modprobe.d/50-sound.conf :
options snd-hda-intel single_cmd=1The documentation says:
single_cmd - Use single immediate commands to communicate with codecs (for debugging only)
OK. I am debugging my sound card until I find a better solution.
