This is a UE4 game... unless they modified the audio subsystem these asserts are probably benign. If FAudio is really crashing, thread backtraces would show a line in the FAudio source. Logs are going to be pretty useless other than to say that your PC doesn’t meet this game’s system requirements, which seems to be the main problem.

My mistake. It works with the XACT audio libraries and thus I figured it could use faudio.

Tested this locally and FAudio is holding up. The assert you see is actually a UE4 bug that may still exist now! They create a mastering voice that bases its channel count on the device info, but the X3DAudio calls are based on a hardcoded 6-channel environment. If they ran the engine against X3DAudioD1_7.dll, Microsoft's library would produce the exact same assertion failure.

You'll want to file an issue at the Proton repository to dig into this further, but the FAudio side seems to be doing well.
