Public bug reported:
to change kernel does not help, I tried 3.11 kernel, 3.8 kernel, 3.5
kernel.
Testing the left and right channel work for headphones output , a
minijack is connected to the ampli.
Removing the jack the notebook ( system76 notebook) is like mute. I have tried
to use alsamixer , all the volume are ok.
application seem to output their audios... but nothing to through the speakers.
thanks
