Headphones not working on firstmix pro


I can't make the headphone work in my FIRSTMIX PRO Gemini using Cross DJ 3.310. I've searched on the forum and found nothing, anybody knows how to solve this? Thanks in advance.
Closed forum. You can only use it as a source of information about MixVibes software

Nevertheless welcome to MixVibes.
The capture gives great info. What is lacking is the Output 2 setting. This usually is named 3/4 or such.
Also consider using an Asio driver as your latency is very high. You likely have significant delay between using a control and the result.
If the controller doesn't have an Asio driver with it you can use Asio4all from Asio4all.com. Install. Start Cross. Go to the menu as in your capture. Select Asio4all driver. Select settings. Select your soundcard in the Asio4all menu.
Btw I have no idea if your controller has a Cue output. If not the Asio4all can be used to join your internal soundcard to it so you can use the headphone output of your PC.
