Forum: MAC Version Technical Support - Topic: Virtual DJ won't play music

I drag music to the drop slots and nothing will play. At first songs would now they won't. I have a numark total control mixer mapped to it...if i hit play on the mixer it also hits play on the virtual dj program and that also wont let it play. I have virtual dj 5.2 for mac and i have snow leapoard. thanks

Okay so I changed the output to headphones and soundcard and now it works. However how come only the left side music slot plays when i hit the right sides PFL switch? If i hit the right sides PFL switch it wont play either side. How do I make it so both PFL switches are on so I can sync the transitions?

bump.

What kind of soundcard do you use?

I have a numark DJ iO. Usually 25-50% of the time I turn on Virtual Dj my song won't play. I end up having to restart the program and my computer a couple times. One thing I can tell you is when i hit 'play' on my controller, the 'play' button in VDJ gets actived too...so why won't it play? Thank you!

P.S - I use a total control. Although I know the reason for it sometimes not playing the live song has to do with the VDJ program itself.

Lol...I think I discovered why. When I have itunes open, and I'm messing around with the playlist in VDJ too, it won't let me play songs in that playlist. I'm not positive if this is why...but when I closed itunes it started playing music in VDJ again. If anyone has any other input that'd be nice..thanks.

I can't check this (don't use iTunes), but it could be that iTunes holds exclusive rights to your soundcard as long as it's running, which means it doesn't allow any other program to use the soundcard.
