I’ve tried compiling the .zip provided with mvn & java but I don’t know anything about what you’ve given and since no snaps/flatpaks, only .deb which gives me no way of installing it on Fedora. Also alien -r convert doesn’t work since it can’t load any audio devices but does not give the “Failed to load your audio devices” error as seen on previous posts.
Devices
KDE Fedora 38
Already using AudioRelay on my Windows PC + Phone, works flawlessly.
