Chael,

A quick solution would be: killall -15 ecasound

Ecasound does have an interface (ECI) providing access to
the Ecasound libraries other programming languages.

I don't know the specifics for Tcl, however, you could
certainly find out by looking into Tkeca, a front end for
Ecasound written in Tcl/Tk.

Joel
