Hello, I own a MSI Megabook S420 notebook and I am having the following
problem:
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
and possibly related:
hda-intel: Invalid position buffer, using LPIB read method instead.
in my dmesg.
The sound used to work through my speakers, but recently it stopped
working and now and then it crackles, which I expect to be a result of a
not correctly supported card. It still works fine through headphones and
microphones and everything else works fine.
More info about my device:

So I would really like to help adding support for this device in your
hda-intel driver, or at least provide enough info for some of you guys
to do it!
Best regards,
Dimitri
