# Mute or unmute an input-group member

`POST /api/pipewire/control/input-groups/{id}/members/{memberIndex}/mute`

Sets the mute state of a member within an input group, addressed by zero-based member index. Loopback nodes have no mute property, so mute is implemented by driving channelmix volume to 0 and unmute restores the saved member volume. Provide `mute` (bool) or `toggle: true`.
