I just got a uca 222 usb interface and i've only been able to get it down to 7.5ms (with crackling dropouts 
The Behringer asio driver didn't offer much adjustability with only 16ms and 7.5ms options at 48000 hz sampling rate. The request block size and request sampling rate options in reaper had no effect either.
I then tried asio4all at the default settings making sure to select behringer usb wdm audio and all i get is a horrible buzzing?
From what i've read most people are able to get 8-10 ms out of this device without issues which would be passable for me.
Any help is greatly appreciated.
