I decided to give FF7 another play through, so I dug through my old games and found it again. I'd used some of the patches here before, and everything worked perfectly, but this time when I installed everything, the SFX and the FMV sounds don't work. Before I was using Windows XP, and now I'm using Windows 7x64. I searched around a bit, and found some promising threads, though none ended up working. I tried using FF7music and Loopbe to no avail. The thing that makes me wonder is that in the tab for Sound in FFconfig my audio driver doesn't show up in that box. The music is working fine, with or without FF7music, so I'm not sure if that has anything to do with the problem. Also, when I test the SFX in ffconfig they work fine, and the sound comes out of the correct speakers. I'm at a complete loss as to what to do now, hopefully someone here has found a solution to the problem.
Edit: It may be that I'm not using Loopbe correctly, but there aren't many options. I changed my Midi settings to use Loopbe, while I run FFmusic through the GS wavewhatever synthesizer. All I have when I open the Loopbe window is a box to either mute or unmute, so I can't imagine that I'm doing that part incorrectly.
