The mute button on my laptop has a led that changes the color based on the status of the audio-master channel. At least it should. There is a slider for the LED in alsamixer but it doesn't change anything. Are there any tests I should run? cat /proc/version_signature > Ubuntu 4.10.0-28.32-generic 4.10.17 --- ApportVersion: 2.20.4-0ubuntu4.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: benjamin 2550 F.... pulseaudio CurrentDesktop: Unity:Unity7 DistroRelease: Ubuntu 17.04 HibernationDevice: RESUME=UUID=4ce0e490-8f95-4de2-9a8f-456e1455444d InstallationDate: Installed on 2015-06-07 (774 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2a Intel Corp.
