Comment 4 for bug 1566596

I'm not 100% sure that I'm following you, but let me tell you what I've done, according to what I've read in the bug report you've linked.

I've run a series of commands which yield the indicated output (see the attachment).

In addition I've later edited the file:

/etc/modprobe.d/alsa-base.conf

adding the following line at the end:

options snd_hda_intel index=0 model=mbp81

and reloaded alsa by running:

sudo alsa reolad

Nothing of this has resulted in the micro working at all.
