I have a usb Behringer Uphoria UMC204 and it seems to work fine at 44.1khz full duplex but anything higher than that I get consistent pops and clicks. I notice it's on the capure side of things as when I have it in playback only it's quiet. I have to say I'm testing this using JACK so this is how I noticed it on the capture only side of things. I'm not sure exactly whats needed to debug this issue. Any help would be appreciated.

Could you send the output of 'lsusb -v', please?

Thanks, Daniel
