DDJ-RB No headphone output

Hi,

I bought a DDJ-RB a few months ago along with a new laptop to accommodate Rekordbox's and the controllers needs.

Although I've been using both for a while suddenly the output to my headphones has stopped working. So far I've been using some Logitech pc speakers as my master output and my headphones plugged into the controller. This has worked fine. However after the recent Rekordbox update my headphones are not producing any sound. 

They do however if i adjust the audio preferences but then lack the master output through my external speakers.

These are my normal settings that up until now have worked fine.

And these are the settings were the headphones work but there is no sound through my pc speakers.In fact there's not any sound unless the Master or either of the CUE buttons are on.

The headphone port isn't bust so it's got to be a setting issue right? All the drivers are up to date and have been reinstalled numerous times.

Can someone please help?

Thanks
