Cecil (or others on the list that have done it...) Any advice on how to get started working with different profiles? Like Joel, I'm a bit nervous about making these kinds of changes (for instance, I don't know exactly how to eliminate services when I have set up a new profile.)
I used to do this kind of low-level stuff all the time, but that was back in the days of CPM, and boot loaders, etc. So, any pointers on setting up an alternate profile, pitfalls, etc.?

I thought I had stripped my systems down but obviously I haven't if you're running that low CPU usage. I don't have experience to dig any deeper without fear of going beyond a point of complete system devastation by my own hands! :-) I have about come to the conclusion that my computers just aren't meaty enough to run 192 KHz with the Edirol, as you note. Sadly, Flex-radio says absolutely nothing about minimum system requirements on the web page. All they do is extol the glorious virtues of the products they recommend then let you find out about the pitfalls on your own, and then you wind up having to spend more money to get things working. That irritates me. Yea, I know this is going to the entire reflector, but that is just the way I feel. This is now the second time I've been in this situation with my SDR-1000's when it could have been avoided by just some simple system requirement statements on the web page. I guess everyone is expected to be a computer expert beforehand. Thanks again for the advice, Cecil. I appreciate it. 73 Joel W5ZN Date: Thu, 05 Jul 2007 13:17:14 -0500 From: k5nwa <[EMAIL PROTECTED]> Subject: Re: [Flexradio] Edirol FA66 Problem To: FlexRadio@flex-radio.biz Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="us-ascii"; format=flowed At 12:59 PM 7/5/2007, you wrote: >I recently purchased an Edirol FA66 and I'm having a trouble when using 192 >KHz.

That is just the way things are, however depending on your efforts there are a lot more optimizing that can be done beyond the recommended options, but few people have the experience to go there. On a dual Pentium III 1GHz with 512 MB RAM and XP SP2, which is an inferior machine to what you have I typically run at less than 10% CPU usage with 96KHz sampling using a Delta-44, this is on a profile that is fairly bare, no networking, therefore no anti-virus, no firewall software, all services stripped that are not required for that one profile.
