Title:
ALSA: hda/realtek: Enable headset onLenovo M70/M90
Status in OEM Priority Project:
Triaged
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
The headset couldn't work on M70/M90 Gen4 on 6.1.0-oem kernel and 5.19
generic kernel.
Lenovo M70/M90 Gen4 are equipped with ALC897, and they need
ALC897_FIXUP_HEADSET_MIC_PIN quirk to make its headset mic work.
The previous quirk for M70/M90 is for Gen3.
[Fix]
cherry picked from commit 4ca110cab46561cd74a2acd9b447435acb4bec5f
[Test]
After applying the patch, the os works fine with the headset mic.
[Where problems could occur]
It's just a quirk for sound/pci/hda/patch_realtek.c, the risk is low.
