Do these mute buttons actually hardware-mute the mic or do they send a keycode to the OS?

- remram 5y agoUsually the second. If you have multiple buttons to do it (for example dedicated button + Fn+F4 combination) then it's almost certainly software.
- tedunangst 5y agoThey seem to do both, at least on some models? On my thinkpad running openbsd, the speaker mute can become desynced. Audio won't play unless both are unmuted. Pushing the button will flip flop the software state, but not the reverse (although I believe that code could be written, it doesn't exist). So if you soft mute, then push button, hardware mutes and software unmutes, but sound still doesn't play.
