HD Radio is delayed in general, but they wouldnt be using hd
so its just the capture day, and there is prob no way around it!
since its audio is usb, it gets captured, then the data is played though your playback device
whats the delay 1second?
it would be inherent to allmost all USB audio devices
the lower the latency, the more cpu u need, and the more chance for audio issues
thats why its buffered
