Describe what's going wrong

The audio latency is quite high by default, i believe it's 500 ms or 1 second. Higher is usually safer in terms of cracking etc so it might be needed sometimes.

Describe what should happen

One should be allowed to set the latency (audio buffer size?) manually so one can achieve lower delay (by trial and error by that user).

Agreed. The audio latency is just way too high and very notable in games, and there is no way to even reduce it let alone remove it. Even in Canary where there is actually a setting to reduce it, it barely improves the latency. Don't know why this has been a persistent issue with Xenia for such a long time.
