[pulseaudio-discuss] [PATCH v2] tunnel-sink-new: Limit the maximum latency to 200 ms

[Tanu Kaskinen]

The default maximum latency is 10 seconds, which is not good,
especially since the tunnel sink doesn't support rewinding. Due to the
lack of rewinding, e.g. volume changes take a long time with large
latencies.
