Sound Disappeared when I selected "Raise Maximum Volume"

As I selected “Raise Maximum Volume” Sound in Audio Volume applet, sound from my laptop speakers disappeared and in settings my speaker isn’t shown.

[Settings & Applet screenshot when Bluetooth isn’t connected]

I can still hear media sounds when I connect my Bluetooth earphones but any sound from plasma like sound when volume is being increased and sound when laptop is plugged in can’t be heard even through Bluetooth headset.

Please Help I don’t know too much Linux.

i had issues with low sound output and found this little app works wonders


  • select sound device with F6
  • raise PCM volume to full (or 84% to avoid distortion)

It gave me two devices, for first one I set it to 82. and second device shows This sound device does not have any controls.
and after exiting nothing happened.
