ALSA only one speaker is working
Hey guys,
I am desperately trying to get the right speaker to work on my MacBook Air 3,2. I tried the whl wiki page including creating an /etc/modprobe.d/alsa-base.conf with "options snd_hda_intel index=1" or "options snd_hda_intel index=1 model=auto" or "options snd_hda_intel index=1 model=mba32".
But somehow speaker-test -c 2 is just able to play sound on the left speaker, the right speaker is quiet.
If someone could help me 
here are some outputs:
lsmod | grep snd:
