Pablo,
I've also experienced the same issue with VMWare Player and Ubuntu 12.04 LTS
x86_64 on a quad core i7 with a USRP N210. I've also tried Linux KVM to no
avail. I ended up creating a USB 3.0 flash drive for my SDR development
environment which had no issues. However, if you are interested in other
applications running in a VM, Linux KVM could be an option for ethernet-based
USRPs.

Hi Pablo -
Have you tried tuning the audio rate a bit? When you see the 'aU's, do you
also hear distortion in the audio?
Cheers,
Ben
