It doesn't list any commands. Just says that it's stopping all commands, then says a command is still blocking.
Honestly, I'm thinging it's a cereproc single-instance issue. I've started sending more voice commands to EDDI to get the audio FX processing from it. I don't think EDDI has a way to deal with cereproc single-instancing. Since VA, can't stop the command, I'd bet money that's where my problem is, in the plugin's TTS routines.
I'm going to try and add a "Stop all playing Sounds" command right before I call the plugin routine, see if that helps.
