Common questions and troubleshooting steps.
My device is missing.
Check that the playback device is connected and enabled in your OS sound settings, then refresh the list. Recording devices are excluded.
My app keeps playing through another output.
Check application-specific routing and exclusive mode. Some apps require restarting playback or the app itself.
Holding a key does not switch outputs.
A long press toggles mute only. Use a short press to switch the default output.
Changing volume does not restore sound.
Volume changes do not unmute the endpoint. Touch the strip or hold and release the key to unmute, and check the assigned device.
Why are volume or mute unavailable on my Mac?
HDMI, DisplayPort and some USB DACs do not expose these controls to macOS. Output switching remains available. Check the inspector for device capabilities.
