Caption Ranker, some of the music, and a lot of the speech in SH4 is in ogg vorbis format. The rest is probably in wav format. Is there a codec for wav on your computer for Linux? I would think there would be, even before any Wine install... You can also check in the game's Options menu, under the Sound settings, and see what the various sliders are set to. The 3D slider on the upper left of that page is kind of wonky, and should probably be left of center, if you've moved it any. On my computer, it messes with the "stereo" field if I move it to the right. I'm using Win7, and I do not remember what happens with it in my Ubuntu 16.x... Are you usiig a built-in sound card on your motherboard, or an after-market thingie?...
