Bug#851404: Acknowledgement (linux-image-4.8.0-2-amd64: Internal speakers don't work after standby on a Toshiba z20t-c-121)
Ok, on a reboot (and working sound), it says
root@michis-toshiba:~# dmesg | grep -i hda

So no difference it seems.
After a
rmmod -f snd_hda_codec_conexant
modprobe snd_hda_codec_conexant
again, sound does not work anymore.
dmesg says:

How can I debug this further?
