Subject: ALSA: hda/realtek: Add quirk for Minisforum V3 SE
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e3474301824926ecce1d45f2ede7ecdda9a35840;p=thirdparty%2Fkernel%2Flinux.git

ALSA: hda/realtek: Add quirk for Minisforum V3 SE

First, adding a generic quirk for Bass speaker DAC avoidance.

This pattern (re-routing the bass speakers off of a DAC without volume
control) seems common enough that having a "model" to match against and
quickly use to verify may be worthwhile.

The alc285_fixup_thinkpad_x1_gen7 routing was selected, amongst the
different options, as it should allow tuning the ratio between both
speaker set.

The routing was verified using `hda-verb`, and picking either 0x00 or
0x01. Either routing made the volume of the bass speakers controllable.

    hda-verb /dev/snd/hwC1D0 0x17 SET_CONNECT_SEL 0x01

This likely will apply for the Minisforum V3, though there isn't a lot
of information to confirm whether or not the identifiers are the same.

This was verified on the Minisforum V3 SE, and the root cause (the bass
speakers routing) was found out by using pink noise, and playing with
the mixers.
