Hey Guys, I got a second RapidRoad USB so moved the clockport version back to my A1200, somewhat as expected the 030 isn't able to drive USB Audio but it does work in as much as the device is picked up and playback is attempted. There are occasional beeps to suggest it's trying to play!
A fast 060 might be able to push it, assuming the clockport has enough bandwidth. Shame I got rid of my 060 lol.
@Jens, I have a strange issue on my A4000, just noticed if I stop the USB stack my Amiga locks up. Have you seen this at all in testing? Otherwise it seems to work fine!
