hi new to this I've got a Traktor s4 with Traktor pro4 software but I'm not getting any sound out of

I think a little more detail would be helpful. I assume you've got the software up and running, imported your music, and analysed it?

How are you connecting the S4 to your speakers? When you load a track and press play what happens?

This is very useful:

Is it an S4 Mk2 or an S4mk3? If MK3 choose S4 MK3 (WASAPI Exclusive.)

Buffer size zero? There's a problem for a start.

I think that is just how it looks if the device is not connected (Or for some reason not seen as connected)

And you are sure it's an mk2 and not an mk1?

Do you see it in windows device manager?
