Replit added system audio integration as an opt-in feature for repls. Users enable it by creating a secret called VNC_ENABLE_EXPERIMENTAL_AUDIO with a value of 1 and restarting the repl. The feature uses a custom RFB proxy written in Rust to transcode PulseAudio into an Opus stream in a WebM container, with an MP3-in-MPEG fallback for browsers that do not support Opus/WebM.

## Evidence

Verbatim from https://replit.com/blog/system-audio:

> That support is finally available today, as an opt-in feature.
