I'm trying to increase the volume from the increase volume button, but this is what it's showing: enter image description here

I also checked the 'Sound' menu in System Preferences, but in the outputs tab everything is perfectly fine. What should I do? No volume is playing on my Mac.

  • Try restarting your Mac. This often fixes the issue.

I searched for the icon you've uploaded… If you see output devices in 'System preferences > Sound > Output', try selecting again the build-in internal speakers. enter image description here

If 'System preferences > Sound > Output' shows no output devices, try a reset of the nvram.

If you have a connected audio device/audio interface that has it's own volume control then you cannot control the volume of that device from your keyboard.
