Ya'll need to stop wasting your time with the Pi, it's a well-documented
issue with USB performance or lack thereof due to the SOC design.  Also note
the IP performance is at least 50% worse than other ARM 9 designs, the Arm
11 is just that a low cost entry level platform

This is where we need to starting going -

And the price is right as well

Hi Jim;

Good to hear from you Duuuude!

Yeh, I figured you were busy with real / revenue generating work.

I played around with all of the buffer parameters and queue size in 
chan_simpleusb and could not get rid of that cyclical raspiness on the 
Raspberry!

When it works - it works well, every few seconds the audio gets raspy 
and then clears up.

I've also been busy with work and now the holiday parties have started 
to kick in! - that's paRties - not paNties :)

Cheers,

Ramesh.
