Hi Al,

I followed your process and also rolled Windows 7 back to Windows  
XP, using the same Firewire v3.5.0.7171 driver.  It works like a  
charm, no distorted audio on receive or transmit like I had in  
Windows 7.  Now I'm wondering if the problem is in the driver or is  
it something in Windows 7.  If there is a problem with Windows 7   
there should be a statement from Flex that suggests we should only  
be using Windows XP.  Also, I'm really surprised that there aren't  
more comments about the problem with distortion in Windows 7 that Al  
and I observed.

I received my Flex 3000 last May and been running it on Win XP and  
Vista 32
on a laptop with no issues at all.

A few weeks ago I decided to upgrade the shack computer to Win 7  
with a
clean install and new hard drive.

The computer is a Dell 420 with a Quad core Q9400 running 4 gigs of  
ram.
Surely enough horse power to run PSDR.



I did the upgrade and downloaded the latest drivers and Power SDR  
from the
Flex site. Everything worked right from the beginning, until I ran  
another
program with streaming media content, whether it be audio or video
concurrently with the flex.



The audio on the 3K would start to garble. If I restarted Power  
SDR, it
would clear for a few seconds then start to garble again.  
Everything would
run fine as long as I didn't multitask two streaming programs.



I did a little research and found out about DPC latency checker.   
Every time
I ran it with multiple streams, it ran off the chart in the red.



I made sure all my drivers were up to date from the dell site and  
also
played around with various buffering in the flex with no success.



Since I never had this problem with XP, I thought I'd roll back the  
Flex
driver to an earlier version. That didn't work at all with Win 7.  
Looks like
you must have the latest driver for 7.



Since I kept my XP hard drive intact, I decided to put it back in the
machine.

I updated the Flex drivers on the XP drive to the latest (It was 2  
versions
back).



Everything is now working fine with XP and I can stream other  
programs along
with the flex with very little latency.



It seems the latest Flex driver may have a problem with Win 7 on my  
machine.
I wonder if  others are seeing the same?
