That’s the power of GitHub. The fork still shows idolize as the author and clearly has gpl3 license (added by idolize). They can change what they want in the original repo, but the fork is covered forever, and ironclad proof of the licensing. If OP’s code is based off this fork, unmodified (of which it’s a fork, also ironclad proof it’s that gpl3 version) then it’s also gpl3. Saaaafe. This should be open and shut on github’s end, just a dumb DMCA report.

Pipewire spatializer. But it looks like you need a special wav file (“HRTF”?) for a specific headset, not sure where is best to source those.

Nothing at all. If things go south on the install I’ll have a clean slate. Really the only thing I have backed up are keys, everything else is nonessential.

There are no “surround sound” headphones (at least not since razer hp1), it’s a gimmick, any advertised as such are using a single driver per side and doing fake surround in software (driver).

You can use any headset and set up various virtual surround programs in Linux, you might want to look into details of that before buying a headset.

You can probably assume if the headset wants to use some windows software or drivers to “set up” the surround sound that it won’t work on Linux the same way, but it is possible to do with other programs.
