Bug#851404: Acknowledgement (linux-image-4.8.0-2-amd64: Internal speakers don't work after standby on a Toshiba z20t-c-121)

[Michael Fritscher <michael@fritscher.net>]

Still applies on 4.9.0-2.

Interesting thing: if I do a

rmmod -f snd_hda_codec_conexant
modprobe snd_hda_codec_conexant

while the sound does NOT work,

I get

As seen on the speaker_outs=0 line, it seems that somehow the speaker is
disabled?

I'll try the same after a reboot (which "fixes" the sound) in a moment.
