Re: [PATCH 0/8] ALSA: hda: Add AW88399 HDA side codec driver for Lenovo Legion

[Thomas <cyberfix@gmx.net>]

Hi,

I found an additional Lenovo system that requires the existing
|ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN|quirk.

*System:*

  * Product: Lenovo Legion 7 16AGP11
  * Machine Type: 83Q8
  * Codec: Realtek ALC287
  * Codec Subsystem ID: 17aa:3956

*Problem:*

The internal tweeters follow the master volume correctly, but the bass
speakers (woofers) remain almost at full volume even at very low volume
settings (e.g. 5%).

This matches the behavior that the
|ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN|fixup was introduced to correct
on other Lenovo systems.

Without the fixup:

  * Tweeters are volume-controlled correctly.
  * Woofers are already loud at very low volume settings.

With

|options snd-hda-intel model=,,alc287-yoga9-bass-spk-pin|

the problem disappears completely:

  * Tweeters and woofers track the volume control together.
  * Bass volume scales correctly across the complete volume range.

The system contains multiple HDA controllers, therefore the model
parameter must be applied to the third controller (|,,|).

It looks like adding the following quirk is sufficient:

|diff --git a/sound/hda/codecs/realtek/alc269.c 
b/sound/hda/codecs/realtek/alc269.c @@ + HDA_CODEC_QUIRK(0x17aa, 0x3956, 
+ "Lenovo Legion 7 16AGP11", + ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN),|

For reference:

|Codec: Realtek ALC287 Subsystem Id: 0x17aa3956 DMI Product: Legion 7 
16AGP11 Machine Type: 83Q8 Kernel: 7.1.3 Distribution: Debian sid|

I have verified that the existing fixup completely resolves the speaker
volume issue on this machine.

Thanks,
Tom
