Lost the ability to control volume remotely

I’m relatively new to all this and have started to fiddle around with sample rate conversion. All seems be fine, however I can no longer control the volume from my phone. I’ve obviously changed something but can’t for the life of me see it. Any help would be much appreciated :blush:
I’m running Rock on a NUC, usb to a Topping d90. This is what I’ve done so far.

Probably because you are using DSD. Try putting it back to PCM.

Really? Is that always the case? Oh well, I probably can’t tell the difference anyway :wink:. Thanks for that.
