So, I'm using alsa-utils to control sound in my arch. Before, I had an opportunity to mute Speakers and unmute Headphones, but know, amixer shows only one option: Master, and no sound is going through headphones. Here is the result of "amixer":

Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 0 [0%] [on]
  Front Right: Playback 0 [0%] [on]
Simple mixer control 'Capture',0
  Capabilities: cvolume cswitch cswitch-joined
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 65536
  Front Left: Capture 16462 [25%] [on]
  Front Right: Capture 16462 [25%] [on]

When I try to change anything in alsamixer, it doesn't have any effect As you can see, i tried to mute the Speaker and unmute Headphones, but volume is still 0%

My question is, do you have any ideas, how to return the capability to control these two outputs separately, not with Master? Thank you in advance.

  • "Before"? What did you change? – CL. Nov 25 '15 at 11:06
  • I'm sorry, but I don't know the exact moment when the situation changed. So I don't know what caused this change. – Daria Zenkova Nov 25 '15 at 11:10
  • Your headphone is muted, select it and hit M – switch87 Nov 25 '15 at 12:43
  • i.imgur.com/Thkyiqw.png It hasn't changed anything. In addition, I checked that if I mute Speaker, I simultaneously mute Master. – Daria Zenkova Nov 26 '15 at 11:57

When PulseAudio is enabled, it becomes the "default" sound device.

To select another sound card, use amixer's --card option:

amixer -c 0
  • I used this prompt. But with "amixer -c 1". It showed me all options of PCH - card, including Speaker and Headphones, but when I use "amixer" again to see the list of options, it shows only Master and Capture again. – Daria Zenkova Nov 26 '15 at 11:59
  • This options affects only that single execution of amixer. – CL. Nov 26 '15 at 12:41
