I am currently using the AGERE OHCI Compliant IEEE 1394 Host Controller 1394bus.sys
Sorry i am unfamiliar with firewire so this is kind of new to me.. What other driver would you suggest? I am also starting to get the same scratchy audio in Winxp X64..

Some times there are 2 or 3 different drivers that windows (all flavors) has available. I have had the problems your saying you have sometimes using the default driver. You can change this in control panel / performance and Maintenance / System / Hardware tab / Device Manager / IEEE 13944 host controller / right click on controller / properties / update driver / DON'T search for new driver / let you choose driver. I am sure you have tried this but just a thought. 73's Bret WX7Y -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Anthony Sent: Monday, February 01, 2010 1:37 AM To: FlexRadio@flex-radio.biz Subject: Re: [Flexradio] Audio tear/scratchy audio To further my original post, I have now in the past 2 days tried Windows XP SP3, Windows 7 Ultimate x64, and Windows XP X64. BY FAR, Windows XP X64 seems to be the most stable, with the least cpu usage. CPU Useage in WinXP X32 was around 15-20% CPU Useage in Win7 X64 was above 35-40% CPU Useage in WinXP X64 was no greater than 10% Are there any tweaks or registry tweaks for Windows XP X64 for firewire? I remember reading something about a registry setting to do in XP to stabilize firewire communications or something? Anyways I figured some of you may be interested in these results - so on my near new system, the winner is XP X64 by a mile. 73 VK3LAJ Anthony -----Original Message----- From: Anthony [mailto:anth...@consultexcel.com.au] Sent: Monday, 1 February 2010 4:20 PM To: 'FlexRadio@flex-radio.biz' Subject: Audio tear/scratchy audio Hi All, When i first got my Flex 3000 i was running Windows 7 X64. This seemed to work flawlessly out of the box. I went back to XP after i could not get some programs running that i needed but found that compared to Win7, XP really sucks. So i went BACK to Win7 (without any hardware changes) and i am getting crappy audio out of PowerSDR 1.18.3. It starts off ok but then after a few minutes it gets scratchy and seems to get worse. If i turn VAC on or off the problem goes away and then re-occurs a few minutes later. My system is a dual core 3.2Ghz intel box with 4gb ram.. Anyone have any ideas?
