Might be worth to open up an issue on Github or a thread on Discord. I haven’t tested pipewiresrc
but there’s probably some clue in the Wolf logs. Besides, have you mounted the host XDG_RUNTIME_DIR, passed the right env variables and so on?
For streaming the host desktop Sunshine might be a better fit btw…
Others have asked for it and I guess some of it might even work given that WSL2 has GPU support. I’ll keep this issue updated as I get some progress on this front!
