Is it the case? I also tried setting codec->power_save_node = 0; in a patch_realtek.c quirk. static void alc274_fixup_pop_noise(struct hda_codec *codec, const struct hda_fixup *fix, int action) { codec->power_save_node = 0; } That initially seemed to work, but when I tested it again a day later after a fresh install, it didn't anymore. I don't know what is different. On the install before, I did some debugging with boot parameters and other stuff, cant reproduce anymore what exactly. I took the line from alc274_fixup_bind_dacs which fixes the pop noise when applied to the devices, but does a lot of random other stuff too not meant for the device. I think I only ever warm rebooted when trying other fixes including that one, maybe that's the reason for the different behavior a day later .. Kind Regards, Werner Sembach > > > thanks, > > Takashi
