Symptoms

There is a serious latency issue when the default output sample rate is higher than 48KHz, but the problem is gone if I have played other 96KHz music first, then there is no latency in game although the output format is resampled to 96KHz.

Reproduction

edid /etc/pulse/daemon.conf
edid default-sample-rate to 96000
pulseaudio --kill
pulseaudio --start

Reproduce RESIDENT EVIL 2 with default-sample-rate set to 96000 in /etc/pulse/daemon.conf, restarting PulseAudio with pulseaudio --kill and pulseaudio --start. Compare the game's audio latency before and after playing 96 KHz music, and use the Proton log if available; done means high-rate output no longer causes latency.
