The closest I got is link which a sent to the list a while ago: http://www.audiostream.com/content/usb-link-dsd-audio-pcm-frames-andres-koch It isn't as clear as a 'real' standard but it contains the needed info. BTW Max, it seems that the current 24-bit format for DSD-over-USB causes problems with modern audio I/F (e.g USB 2.0 devices using UAC 2.0 and some other FW devices) only supporting 32-bit samples (and sometimes 16-bit as well). So we could either switch to 32-bit sample format for DSD-over-USB or let MPD convert on the fly. Personally I vote for the 32-bit sample format as most, if not all, devices supporting DSD-over-USB will accept that format.
