Check whether these GPIO settings are effective. Hi Zhang, I tested these verbs on card 1 (/dev/snd/hwC1D0, Realtek ALC236). Results: 1. The GPIO mask (0x716) and direction (0x717) on root node 0x01 need to be explicitly initialized first: sudo hda-verb /dev/snd/hwC1D0 0x01 0x716 0x0f sudo hda-verb /dev/snd/hwC1D0 0x01 0x717 0x0f 2. The mic-mute LED (F8) is verified to work cleanly on GPIO 0 using active= -low logic: - Turn ON: sudo hda-verb /dev/snd/hwC1D0 0x01 0x715 0x00 - Turn OFF: sudo hda-verb /dev/snd/hwC1D0 0x01 0x715 0x01 3. The keyboard does have a physical LED indicator on the F5 key (speaker mute), but it did not react to any standard GPIO bit toggles (0x02, 0x04, e= tc.) on node 0x01. Could you provide any hints or specific coefficient/verb sequences to test = for the speaker mute LED on this ALC236 revision (Subsystem ID 103c:8dc9)? Alternatively, is there an existing ALC236 fixup in patch_realtek.c you'd recommend building against to test both LEDs? --=20 You may reply to this email to add a comment.
