John, Two other suggestions,
First check the DPC checker to see if you can use Normal mode. I noticed that on a fast machine that the Normal will run smoother than the Safe Mode 1 in the FireWire driver. Just the opposite from XP.. Second you may need to move to the Legacy OHCI Windows FireWire driver instead of the one you are using.. Follow this procedure.. http://kc.flexradio.com/KnowledgebaseArticle50433.aspx Check on them both.. 73, Dudley WA5QPZ FlexRadio Systems (512) 250-8595, Option 2 Email: [email protected] Web: www.flex-radio.com "Tune in excitement!" ™ On Fri, Oct 8, 2010 at 1:59 PM, <[email protected]> wrote: > > > > Flex 5000A. > > ver. 2.0.8 > > Sample rate 192K, 1024 buffer > > Windows 7, Pro, 64bit > > > > PC- Intel E8400 3ghz cpu, 5G RAM, no wireless card to router, wired > direct to router for internet > > no IRQ conflicts. > > Average cpu % <20% > > > > Just installed Windows 7 64 bit and having an issue with audio cracks or > static during network internet traffic.
