    [Solved] Alsa issues- amixer set Master (x) not working

    On Fedora 24. Gnome 3 / XFCE

    Not entirely sure what I did (between uninstalling thunar, thus xdesktop as a result, or trying out openbox [reinstalled and removed], or reinstalling XFCE), but "amixer set Master toggle" in terminal now results in "Unable to find simple control 'Master',0" Consequently, keyboard bindings for XF86AudioMute/RaiseVolume/LowerVolume no longer work.

    Ergh. Also, there doesn't appear to be a Audio/Sound Manager in Settings Manager (XFCE)

    Sound and sound control is working though through pulseaudio. Everything still works in Gnome (except "amixer set Master (x)" in terminal)

    If it helps:

    ==
    $ aplay -L | grep ARD

    Code:
    hdmi:CARD=Generic,DEV=0
    sysdefault:CARD=SB
    front:CARD=SB,DEV=0
    surround21:CARD=SB,DEV=0
    surround40:CARD=SB,DEV=0
    surround41:CARD=SB,DEV=0
    surround50:CARD=SB,DEV=0
    surround51:CARD=SB,DEV=0
    surround71:CARD=SB,DEV=0
    ==
    $ cat /proc/asound/cards

    Code:
    0 [Generic        ]: HDA-Intel - HD-Audio Generic
                          HD-Audio Generic at 0xf0244000 irq 26
    1 [SB             ]: HDA-Intel - HDA ATI SB
                          HDA ATI SB at 0xf0240000 irq 16
    ==
    $ amixer scontents

    Code:
    Simple mixer control 'IEC958',0
      Capabilities: pswitch pswitch-joined
      Playback channels: Mono
      Mono: Playback [on]
    ==
    $ amixer set IEC958 toggle

    Code:
    Simple mixer control 'IEC958',0
      Capabilities: pswitch pswitch-joined
      Playback channels: Mono
      Mono: Playback [off]
    (Sound still works)
