Comment:
@ukbeast I only have two games with this problem currently.

1. TES IV: Oblivion requires GStreamer plugins for MP3 to have functioning music, oddly enough, it does not require it for the voice acting or any sounds that are played as MP3.
2. Earth 2150 requires MP2 audio support in GStreamer to playback music at all.

Most of the games I play have built in support and don't touch DirectShow (quartz.dll) at all though. Freelancer is a good example of this in particular. The game uses MP3 contained within RIFF WAV files for the music, voice acting and some (not all) of the sound effects.

gst-plugins-ugly1 has no 32-bit multilib so this causes a lot of problems with Wine's GStreamer usage, but that's already been a issue opened here. #29118
