Mute or unmute your mic in OBS from a routine

OBS: mute or unmute changes the mute on one of OBS's audio sources, such as Mic/Aux or Desktop Audio. It works through OBS's own mixer, so only the stream and recording are affected. This step needs KeyRoutines Pro.

KeyRoutines Pro is a one-time $29.99 upgrade for up to 2 PCs.

How it works

  • Pick the source from OBS's list and choose mute, unmute, or the other way round.
  • Windows' own mute and volume stay as they are; only OBS's mixer changes.
  • If the source is already in that state, nothing is sent.
  • A source with no audio, like an image, fails with a clear message.

Routines that use it

Push-to-mute on stream

A Hotkey toggles your mic in OBS so viewers can't hear you cough, while Discord still can.

Mute on the break scene

When OBS scene changed fires for Be Right Back, mute Desktop Audio; unmute it when you switch back.

Silence game audio for a call

When Mic or camera in use sees Discord start using your microphone, mute the game capture source in OBS.

Questions

Does muting in OBS mute my mic in Discord or other apps?
No. It only mutes the source inside OBS, so your stream and recording go quiet but other apps still hear you. To mute the device for all apps, use Windows' Mute or unmute step instead.
Can I toggle mute with one key?
Yes. Set the step to toggle and trigger it with a hotkey.
