Well, my problem with the -d option of the sox play command is solved, and it works as Keith originally suggested. It turns out I had outsmarted myself by placing a dummy play command in /usr/local/bin which was designed to decide whether to call the system command in /usr/bin, or to ignore the sound request. That allowed me to silence my computer or allow it to make sounds by setting a flag somewhere. What I was doing was only passing a single argument along from my dummy command to the real command, and the solution was simply to change "$1" to "$*" in my dummy. It's always better not to shoot yourself in the foot if at all possible. Chuck -- The Moon is Waxing Gibbous (85% of Full) "Things are in the saddle, and they ride mankind."
