Comment 12 for bug 110599

I've got the same problem with a Realtek ALC861 on a Toshiba A7. I got it somehow fixed by doing this:

1. disable "full duplex" of "artsd" (full duplex sound still works)

2. unload/load the driver. This is done by

a) stopping the sl-modem
b) stopping artsd
c) unloading the module
d) loading the module
e) starting sl-modem
f) starting artsd

I guess there is an easier way. I do also have

options snd-hda-intel model=auto

in my modprobe.d/alsa-base. With "position_fix=1" I do also get no sound from the mic.
