Audio currently sounds very wrong, with many things sounding way too loud. The game would seem to be relying on OpenAL to make far away objects be quiet or silent.

I would wonder if the effort in getting all these OpenAL effects is worth it. Would it be better if OpenAL is forced to use ALSA or SDL2 internally, which case it can do all its audio processing itself and all libTAS has to care about is OpenAL using ALSA/SDL2 internally?

Seems like overriding what OpenAL will try to use is possible with the ALSOFT_DRIVERS environment variable: https://github.com/kcat/openal-soft/blob/3ccde151c609ba8fed59f07277ca5c719b2b92fc/docs/env-vars.txt#L26
