AV sound

I have one of those inevitable telephone ringing effects that must be stopped dead when the phone is picked up. The AV doesn’t support dedicated fade cues as do Qlab and SCS but any cue will serve providing it doesn’t affect anything else. However I have found that a snap cue with zero fade time doesn’t seem to work. Put 0.2 into the fade times and it does. 

Also, is there any chance of adding a pan control to the audio?
