I recently had to reformat the hardrive and re-install Windows XP Professional. I then installed PowerSDR 1.18.3 along with the 3.5.0.7171 firewire driver. Firmware is 1.3.0.8. I also installed .NET 3.5. All was installed per instructions in the Knowledge Base. I have re-installed all twice and started with a new database each time. I am using a dual core computer that was working fine with an older version of PowerSDR before the re-install of the operating system.

The problem I am having is that even with a CPU usage of only around 20%, I constantly get audio drop outs and freezing. I have tried multiple settings of the sample rate and buffers and I still get the drop out/freeze up problem.

Any suggestions would be appreciated greatly!!
