On most setups, moving the latency control while sound was playing did nothing at all — neither up nor down. It only ever took effect if you set it before connecting, which made it look like the setting was simply ignored.
- The control was sending its value somewhere the audio never looked, so the receiving side quietly stayed on its starting value for the whole session.
- Even once that reached the right place, the change crept in so slowly that a large move took over two minutes to arrive — still indistinguishable from nothing happening.
Move it now and the delay follows within a few seconds. There's no gap and no click while it changes. Lowering takes effect straight away; raising can't be instant, because the extra cushion has to be built out of the sound still arriving, so RemSound plays very slightly slow for a moment while it banks the difference — you can hear it stretch, and that's the change happening.
