I recently vibe coded a jack mixer in Rust. It can ingest and relay audio via LAN. I have around 40 ms latency, 50-60 ms if relaying via wifi.

It would solve the issue in a similar way. One pc runs the mixer. The mixer has an input channel for local mic.

Other PC broadcasts their mic to the mixer, which comes in as 'channel 2'.

You can even have music playing on your local PC, either the mixer or broadcaster creates a local sink.

It's all then mixed in the mixer, there's 3 outputs. You could say use the main out to send to discord.

And the monitor line would be used to output Discord audio, which can then be relayed to the other PC for realtime listening.
