Hi Takashi, I test the ALC236 for do below line. It passed on reboot OS. ==> alc_update_coef_idx(codec, 0x46, 0, 3 << 12); /* 3K pull low */ I also test it without 3K pull low. It also passed on reboot OS. I think this machine was the special case for this issue. Hi Joseph, Could you test it with below model name? ==> alc-chrome-book BR Kailang. > -----Original Message----- > From: Takashi Iwai <tiwai@xxxxxxx> > Sent: Thursday, May 25, 2023 6:17 PM > To: Kailang <kailang@xxxxxxxxxxx> > Cc: Joseph C.
