The mixer wrote silence between sounds to keep the line running, which left
the playback buffer (400 ms on the PipeWire ring) full of it, so a sound the
user had just triggered only started once all of that had drained. Wait for
the next sound instead, leaving the buffer empty between them.
Opening the line costs a device round-trip of its own, so hold it for 30 s of
quiet rather than dropping it after 3 s and paying that on the next action.
