Public bug reported:
I just bought a laptop, and had some trouble making sound work. After
some reading on the forum and experimentation, I managed to make it
work, by passing the model=uniwill-m31 to the snd-hda-intel module. So,
maybe the alsa developer may be interested in adding this model to the
database so that it will be automatically recognized in next version of
the drivers.
