i found out that using the following command suppresses the noise for a few seconds, then it continues: $ cat /proc/asound/card*/codec* | grep "Vendor Id" Vendor Id: 0x10ec0257 Vendor Id: 0x8086281c
is there any suggestions what might be the real cause of noise? i don't have much experience doing kernel development, so I would appreciate it if someone guided me in the correct direction to fix this

The headset push button cannot work properly in case of the ALC257. This patch reverted the previous commit to correct the side effect.

As it's a regression, the revert is fine. Now applied to for-linus branch.
Meanwhile, we'd need to fix for IdeaPad 3 in a different way. e.g. add a quirk entry to set alc_eapd_shutup or so. Adding Parsa to Cc for the further work.
thanks,
