Public bug reported:
Title: MSI Cyborg 15 A12UDX: Internal speakers silent, ALC256 speaker_outs=0,
missing kernel quirk for subsystem 1462:13e8
Description: Internal speakers completely silent on MSI Cyborg 15 A12UDX. Codec
is Realtek ALC256, subsystem ID 1462:13e8. dmesg shows speaker_outs=0 at boot —
the kernel autoconfig does not assign any speaker outputs. No quirk exists in
patch_realtek.c for this subsystem ID. Headphones via jack work correctly. A
one-line quirk addition to patch_realtek.c is needed, similar to other MSI
ALC256 boards already in the table.
