Speaker Mute LED (F5): - Select COEF index 0x07: hda-verb /dev/snd/hwC1D0 0x20 0x500 0x07 - Turn ON: hda-verb /dev/snd/hwC1D0 0x20 0x400 0x01 - Turn OFF: hda-verb /dev/snd/hwC1D0 0x20 0x400 0x00 Summary of both working controls on ALC236 (103c:8dc9): 1. Mic Mute LED (F8): Node 0x01, GPIO 0 (active-low) - Setup: 0x716 0x0f, 0x717 0x0f - ON: 0x715 0x00 - OFF: 0x715 0x01 2. Speaker Mute LED (F5): Node 0x20, COEF 0x07 - ON: 0x500 0x07, 0x400 0x01 - OFF: 0x500 0x07, 0x400 0x00 This combination appears identical to the alc236_fixup_hp_mute_led / coef 0= x07 fixup pattern. Looking forward to testing a patch against patch_realtek.c w= hen available. --=20 You may reply to this email to add a comment.
