[Bug 573395] [NEW] [STAGING] sounds only from subwoofer on MSI GT735 laptop

[Samium Gromoff]

Public bug reported:

The roverbook pro p735-vhb laptop is a rebranded MSI MS-1721, which is a
MSI GT735.

The DMI info identifies it as a GT735 (see info).

The speaker configuration is 4.1 -- 2f/2b/1s

The issue manifests itself as lack of use of the front/back speakers --
all sounds come out from subwoofer.

No amount of "options snd-hda-intel model=xxxx" solves the issue -- no model I chose out of about 20,
from those listed in kernel://Documentation/sound/alsa/HD-Audio-Models.txt fitted.
