 BLooperZ (rzil on the forums) is
 [https://forums.scummvm.org/viewtopic.php?f=8 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).
