I'm under the impression that the reason why clockport USB adapters cant work with audio cards is because they require the USB to operate in isochronous mode.
I'm noticing that certain higher-end USB DACs claim to operate in asynchronous mode and also claim not to require any custom driver.
For example:
HIFIMEDIY SABRE U2
DragonFly DAC
Atune t1 mk2
Would any of these work with ClockPort USB?
Thanks!
