# How to set volume via amixer

1) check device #(2 for example)
2) see available commands:

➜  ~ amixer -c 2 scontrols 
Simple mixer control 'PCM',0
Simple mixer control 'PCM Capture Source',0
Simple mixer control 'Line In',0
Simple mixer control 'Mic-In/Mic Array',0
Simple mixer control 'Auto Gain Control',0

3) ➜  ~ amixer sset -c2 PCM 5%+
