No sound coming out the Master 1 port

Hi Everyone,

I have the current driver installed for Mac. My macbook is on Mac OS 10.14 Mojave. After connecting the USB cable into the computer and running Serato DJ Pro, it stated "Failed to connect audio" as an error. The software never showed the 2 decks it would normally display. Since Serato did not work, I tried another DJ app called DJ Pro 2 and it connected with the controller. I was able to move the faders, and other knobs and also load tracks. The problem is instead of having the output go to my PA speakers on the Master port, the sound came out of the computer speaker. I turned on Bluetooth on my computer then went into the output section of the software and selected the Bluetooth speaker and was able to run every like it should but Bluetooth is not as good as a direct connection to the speakers through the Master 1 port.

Before purchasing the SL2, I had a Newmark NVII and as soon as I plugged the USB cable into the computer, the computer speakers were disable and all sound came from the controller. I was expecting the same thing to happen with my new SL2 but it did not do that.

Since I'm new to the SL2, what did I do wrong? I have the master level, the trim and the faders up and the cross fader in the correct position and was expecting sound but nothing happens when I play the track.

Thanks in advance.
