RE: iPad and external DACs

"...."

That's what I figured already.

The question is if I can make the USB audio interface chip (probaly depends on brand and firmware) announcing two different modes (external/USB powered) with related power consumption.

If the USB audio device is externally powered it should be able to announce
zero consumption. Obviously many devices fail on this feature.

Cheers
