Hey - I got the games working on Linux but there is no music? I have the files for the ogg but where do I put them?

For TFE at least, they should be in the game's base install directory. They're also archived as .GRO files (1_00_music).

You can unpack the GRO archive as if it were a normal .ZIP archive and you should be able to see how they have the music laid out in it (organized by folders for the most part, named according to levels with a medium and peace version of the track in each one).
