Dear Marcus,
Any ither suggession please?


You didn't answer my questions:

Are you getting overrun indications on the console?'O' character 
being printed out

Does reducing the sample rate help?
What version of UHD are you using?
Does the 'rx_multi_samples' example application work properly?

Additionally:

What kind of computer?  What CPU?   What kind of USB controller?  Is 
this on Linux?  Under a VM or on the actual hardware?
