I mean if you are desperate, you could close the program and shell another instance, using a file to direct the new instance to a different part of the program. That file could also hold and put back any variables into the new instance.

If you run the code, be sure you understand the first line about the file it creates and what you have to name the file or change the SHELL name to get it to work when it gets compiled. Here's what I'm talking about...

Code: (Select All)

' Caution, this makes a file called blahblahblah.tmp. ALSO IMPORTANT: You must name and compile this file as untitled(9). or change to another name and use that name in the SHELL call.

IF _FILEEXISTS("blahblahblah.tmp") THEN KILL "blahblahblah.tmp": GOTO 101

' Q: how do you stop a sound playing with the Sound command?

CONST FALSE = 0
CONST TRUE = NOT FALSE

DIM iLoop AS INTEGER
DIM in$
DIM bQuit AS INTEGER

DO
    bQuit = FALSE
    CLS
    PRINT "Start playing some sounds..."

    ' Quick ascending tone signals that we are starting
    FOR iLoop = 400 TO 500 STEP 5: SOUND iLoop, .3: NEXT iLoop

    ' Middle sound (goes on a long time, how to turn it off?)
    FOR iLoop = 1 TO 2000
        SOUND 25000 - (iLoop * 10), .1
    NEXT iLoop

    ' Quick descending tone signals that we're done
    FOR iLoop = 500 TO 400 STEP -5: SOUND iLoop, .3: NEXT iLoop

    PRINT "Finished generating sound."
    PRINT
    PRINT "Now, how do we stop it playing or clear the SOUND queue?"
    PRINT
    PRINT "WARNING: "
    PRINT "Options 1-3 can cause program to freeze or act strangely!"
    PRINT

    PRINT "1. Try stopping the sound with SOUND 0,0"
    PRINT "2. Try stopping the sound with SOUND 37,1"
    PRINT "3. Try stopping the sound with BEEP"
    PRINT "4. Play it again"
    PRINT "5. Quit"
    PRINT

    DO
        in$ = INKEY$
        IF in$ = "1" THEN
            OPEN "blahblahblah.tmp" FOR APPEND AS #1: CLOSE #1
            SHELL _DONTWAIT "untitled(9).exe"
            STOP
        ELSEIF in$ = "2" THEN
            SOUND 37, 1
        ELSEIF in$ = "3" THEN
            BEEP
            END
        ELSEIF in$ = "4" THEN
            bQuit = FALSE: EXIT DO
        ELSEIF in$ = "5" OR in$ = "q" THEN

So the part that sucks is you momentarily lose your program window. I mean the whole approach sucks, but losing the window really sucks. Now if @Spriggsy swings by, he might know of a way using Windows API to kill the sound, but if you are on Linux, that won't help you.

@Dav works a lot with sound, but I don't know if he also works on Linux, or just Windows.

Hopefully someone else has a better idea than mine. It will work, but it's ugly.

You'd need to either open up a WAV file and then just allow it to continue playing using SNDLOOP until a certain key is pressed OR you can do something using the PlaySound function from Win32. You'd still need to use a WAV file OR learn how to make the WAVE resource in memory and pass it to the function. The function can run asynchronously and then you can kill the sound whenever you want.

I've never messed with the SOUND function before but maybe you should look into SNDOPENRAW, SNDRAW, and SNDCLOSE instead since you are working with frequencies and such. Those would allow you to kill the sound whenever without having to do some hacky thing with the C backend, Win32, threading, or premade WAV files.
