Player 6 brings atleast 1 'unit name' to 'turn off music'
i have a wav playing when the map starts which is a song. When the unit is moved into the location i want the music to stop.
Player 6 brings atleast 1 'a diff unit' to 'change song'
with this one i want the current song to stop and another one start playing
this are prolly simple triggers they just not working for me
It's not possible to stop a wav once it starts playing. One workaround to this is to cut up your music wav into smaller chunks, so that it will stop playing sooner.
Blizz should add "Stop Sound" and "Loop Sound"
They don't care about starcraft that much

Then lets not care about blizzard that much.

alright what ill do is just set a timer from when the wav starts to when the unit is moved into the location and then just modify the wav to that amount of time which should work.
Setting a timer won't do anything to your wav file, and if you set the switch (or whatever mechanism you use to stop the music from looping) after the timer, the music will still loop one more time before stopping.
I would just give a text message notifying the player that the music will stop at the end of the track.
I'm pretty sure that changing the transmission time only changes the length of time that the speaking portrait is shown for. It doesn't affect the amount of time that text shows, and I'm pretty sure (haven't tested) it doesn't affect the amount of time the WAV plays for.
WAV files can not be "stopped". There is no possible way. You will have to cut it up and play it in a sequence if you want it to stop.
