I had to do a system restore after I lost all sound in CbB, despite all settings being correct. Also, I experienced some strange behavior yesterday with soloing/unsoloing. I went back to before the latest update. Should have followed my rule of not updating just for the sake of updating. I did it to see if TTS-1 would work in the latest version. It didn't, and then things just went from bad to worse. Going back to earlier version solved all the problems except TTS-1, which continues not to work.
