Another update:
If I enable/disable sound or serial port from the vmware player menu bar the
audio is fine for several 10s of seconds. So this is clearly a vmware player
issue.
As for utilization, I can run the 320 kHz wide FM demodulation example
inside vmware/ubuntu on a winxp host and the system reports about 20%
utilization of my 1.5GHz processor. So it seems to me that I get about 90%
efficiency on both USB2.0 and the processor running gnuradio inside vmware,
i.e. 10% penalty for virtualization.

Update: I'm not exactly sure what I did to fix but disabling the ESD (sound
mixer?) seems to have fixed it. All the GRC examples now run except that
they have choppy audio. This appears to be a vmware related issue because
it happens in command line too.

First off, vmware is not a supported platform.
If it works for you, great. If not, please try to reproduce the
alleged problem on real hardware.
Also, even if vmware was supported, you haven't provided us the first
clue about vmware version or host OS and version.
For those of you who are fans of virtualization, I'd be much more
interested in hearing about Xen than vmware ;)
Thanks,
Eric
Sorry, my host os is win xp pro and I'm using the vmware player beta 2.0.
My usrp benchmark gets 16 MByte/s reliably and sometimes 32 MByte/s.
Also, I was able to run the GRC wfm_recv_tvrx.grc.xml demo okay except for
choppy audio which apparently is unrelated to GRC because the same happens
with the command line version. But programs like "phone tones.grc.xml"
don't do anything?
Thanks,
Clark
