Hi,



I built a FM receiver working with a LiveUSB and a USRPB100 device. It
worked fine, but when I installed Ubuntu and GNURadio in a virtual
machine,
the audio is distorted. The console types aU letters. But I generate a
wav
file and the quality is good, the problem is with the audio sink.



Regards,



Pablo.

USB and Audio performance in VMs is highly variable and unpredictable.
Sometimes it's fine, sometimes it's really poor.

I was unable to get GRC to perform acceptably under VMWare on a very up
to
date system. The USB support is very slow.

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
