After bit-perfect ALSA Direct grabs a DAC exclusively (hw: + D-Bus reservation), the device stays sequestered and is invisible to PipeWire, so switching back to the PipeWire backend can't see it without restarting the app. Tauri had a refresh affordance for hot-plugged DACs; this is the refresh plus an explicit release, in one button. Backend: Player::release_device() / AudioCommand::ReleaseDevice tears the stream down immediately (cancelling the deferred drop), freeing the hw: grab + its reservation, then un-suspends the parked sink and resets any forced graph clock (both self-gating). It does NOT reopen, unlike reinit_device which would re-grab the device. UI: a refresh-cw icon button beside the Output device select, propagated through the settings callback chain to handle_release_device, which releases, waits for PipeWire to reclaim, then re-enumerates so a freed or hot-plugged DAC reappears without an app restart. cc
