I'm running 14.04, and I was told I could use amixer
to control volume via the command line. For example, to mute sound you would use
amixer set Master mute
The output for me is
amixer: Unable to find simple control 'Master',0
So I did some man reading and found out I needed to replace Master with the name of my laptop's mixer control. Typing amixer
returns:
Simple mixer control 'IEC958',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [off]
So naturally, I enter amixer set IEC958 mute
but all I get is
Simple mixer control 'IEC958',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [off]
Once again. I've tried sset
and some other commands but every single one returns the same text. Also, why is there no "Master" or "Speaker" controls? Is there something I'm doing wrong?
