Surround sound support

[nickbailuc]

I've got a 5.1 system connected via USB soundblaster running on an M1 macbook air on Debian Linux (I'm using stock PipeWire). It surprisingly works great natively and out of the box with most games that use OpenAL (even really old ones like Quake and Unreal Tournament, S.T.A.L.K.E.R. via Open X-Ray).

With this verion of source I noticed that I only get the "2 speakers" option in the in-game menu despite having the 5.1 audio card being the only one currently enabled in the system. Is there support for 5.1 at this time, and can it be forced as a launch option or an in-game console command?

Source isn't support surround sound for macos/linux. There is no way to force it.
I can try to implement it, why not.
