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?
