BLooperZ (rzil on the forums) is
[https://forums.scummvm.org/viewtopic.php?f=8&t=14506 currently making
scripts that convert the audio from the Full Throttle into a format
compatible with ScummVM]. One notable hurdle with this is that the
cutscene audio is encoded as 5.1 alternative (2 Fronts, Center, LFE, Rear)
Ogg Vorbis. When placed as-is next to a zlib-compressed .san file, ScummVM
simply treats it as mute (or ignores it?). Whilst this is easily rectified
by downmixing to 2.0, I see no reason why this cannot be handled by
ScummVM itself, as it is already a pre-mixed audio stream.
What I am proposing is that ScummVM allow up to 8-channel surround sound
(including the optional layout metadata) and either output to the audio
device based on the file's layout metadata (or
[https://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-810004.3.9 the
format defaults] if none are available) or downmix to 2.0 (preferably as a
togglable downmixing mode option).
