Missing audio settings?

Hi guys,

I recently wanted to try out a RPI as a mediacenter again. So i bought a rpi3 and installed OSMC and everything seams to be working out great BUT, where are my audio settings?

All I can change is output device, nr of channels, keep audio…, Enable DSP, GUI sound and reset.
Where are my passthrough options etc.?

I use HDMI and connect it to my Yamaha reciever. This is usually no problem but i cant seam to get DTS out for example. What am I missing?

Bottom of settings screen, change settings level to Advanced

Thanks alot that did the trick!
