Red S/PDIF light in MacBookPro11,1

asked 2015-11-10 14:07:16 -0500

I cannot turn off the red S/PDIF light on my 2014 Macbook Pro 11,1. I have tried the usual method such as: amixer -c 0 sset "IEC958",16 off and amixer set IEC958 off.

Here is my output of amixer -x 0: Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'IEC958',1 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'IEC958',2 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on]

Notice that it is missing the '16' on the 3rd control. I have tried toggling all 0,1,2 on and off but no dice. Any ideas?

Could be this old bug, resurrected on some newer Macs.
