I am using TP3 and a custom mapping to use it with a DDJ SX2.

However I have an odd situation.

When I want to play music just via the laptop and Traktor I get sound through Deck B but NO SOUND from Deck A.

The VU meter on Deck a indicates sound coming through it but nothing comes through the master output.

I have checked the audio set up 100 timws to ensure it's the internal sound card. I've even downloaded an ASIO4ALL driver and tried that and only getting Deck B.

Any ideas?

Thanks Bart
