[PATCH] ALSA: hda/realtek: Add bass speaker quirk for Lenovo Yoga Pro 7 14IRH8

[Cristian Verde]

The Lenovo Yoga Pro 7 14IRH8 suffers from missing bass speaker output and
broken volume scaling (5% volume plays as loud as 100%). The system shares
the PCI SSID 0x17aa:0x3852 with the older Lenovo Yoga 7 14ITL5, causing the
ALSA driver to mistakenly match on the PCI subsystem ID and apply
ALC287_FIXUP_YOGA7_14ITL_SPEAKERS. That quirk only powers on the amplifier
without routing the 4-speaker DAC pins.

Add a fixup helper that disambiguates models by checking the HDA codec
subsystem ID (codec->core.subsystem_id). When the Yoga Pro 7 14IRH8's codec
SSID (0x17aa:0x38b1) is detected, apply ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN,
which properly configures pin 0x17 as a speaker output and hooks it to the DAC
volume controls. Fall back to ALC287_FIXUP_YOGA7_14ITL_SPEAKERS for older
hardware sharing 0x3852.

This doesn't apply cleanly on the latest code.
Please rebase to sound.git tree for-linus branch (or at least 7.3-rc2)
and resubmit.


thanks,
