Re: [Discuss-gnuradio] Discuss-gnuradio aUaU FM receiver
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.

I was unable to get GRC to perform acceptably under VMWare on a very up to date system. The USB support is very slow. Mike Harpe, N4PLE Sellersburg, IN USA On Fri, May 16, 2014 at 11:08 AM, Marcus D.

[Discuss-gnuradio] aUaU FM receiver
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.
