Modifying audio capabilities of Radio/Touch?

[RadBadMark]

Hi there,

I'm trying to change the audio codec order of preference of the Radio/Touch, but just can't see how to do it!

I want to prioritize flac over ogg - I've done something similar for my classic, receiver and squeezeslave successfully by modifying files on the server side, but for Squeezeplay devices I think i need to alter the ordering of the capabilities defined as part of HELO message - but i can't actually find anything to modify on the device itself.

Can this even be done? Any clues to point me in the right direction would be very welcome!
