The patch changes two places (the change in alc_shutup_pins() and alc256_shutup()), and I guess the latter is the culprit. Could you verify that only reverting the latter fixes the problem?
Yes, only reverting the latter fixes the problem. I just tried a kernel consisting of 6.3.2 plus the below change, and it works fine:
--- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -3638,8 +3638,7 @@ static void alc256_shutup(struct hda_codec

/* If disable 3k pulldown control for alc257, the Micdetection will not work correctly * when booting with headset plugged. So skip setting it for the codec alc257 */
if (codec->core.vendor_id != 0x10ec0236 &&codec->core.vendor_id != 0x10ec0257)
if (codec->core.vendor_id != 0x10ec0257) alc_update_coef_idx(codec, 0x46, 0, 3 << 12); if (!spec->no_shutup_pins)OK, thanks for confirmation.
Kailang, could you check this issue?
OK. I will take it a look for these days.
Kailang, any chance to get this fixed?
Sorry! My test machine didn't work. I couldn't have a machine to do this test. But I find one ChromeBook with ALC236 today.
Thanks!
I already submitted a PR to Linus for 6.4-rc4, and the next PR will be likely in two weeks, so we have a bit of time :)
