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

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.
