To resolve this, amixer must have the device flag set to 'pulse': This will cause amixer to ask Pulse Audio to do the toggling rather than toggling it directly.Because of this, Pulse Audio will correctly unmute Master as well as any applicable output.If a specific application is muted or low while all else seems to be in order, it may be due to individual ).

If you experience low volume on internal notebook microphone, try setting: If changing the volume in specific applications or simply running an application changes the master output volume this is likely due to flat volumes mode of pulseaudio.
Before disabling it, KDE users should try lowering their system notifications volume in System Settings - Manage Notifications under the Player Settings tab to something reasonable.
If this is found to be inconvenient, asinine, or otherwise undesireable, relative volumes can be enabled by disabling flat volumes in the Pulse Audio daemon's configuration file: Per default, it seems as if changing the volume in an application sets the global system volume to that level instead of only affecting the respective application.
Applications setting their volume on startup will therefore cause the system volume to "jump".
