Make sure that you are not using SpeedStep with the laptop that ramps down processor speed to save power and generate less heat.
Also, laptops are not equal to desktops in performance with the "same" CPU being used. Laptops cut corners to get the longest battery life at the expense of high performance. You may have just hit the limit using the FA-66 ASIO driver @ 192K. You may need much larger hardware (FA-66) buffers. What are your buffer settings? BTW, the D44 soundcard uses only PCI the bus, which is more efficient than the Firewire / PCI bus combination for the FA-66. If you are using a mobo Firewire host controller, some of the mobo implementations of these chip sets are taxing on the system too since they share interrupts with other system devices. A PCI-E connected device usually has the bus interrupt to itself and does not share with other devices. -Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joel Harrison Sent: Thursday, July 05, 2007 1:59 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Edirol FA66 Problem I recently purchased an Edirol FA66 and I'm having a trouble when using 192 KHz. Everything works fine on 96 KHz, but on 192 KHz the CPU usage is pegged out a 100% and the system locks up. It does the same thing on two different computers on two separate SDR-1000's Here are my specific details. Computer 1 - Compaq EVO N610 Notebook, Intel Pentium 4, 2 GHz processor with 1 Gb RAM. Normal CPU usage on 96 KHz is approximately 35% (Same average CPU usage with standard sound card, Presonus Firebox, used on this system) Computer 2 - Dell Optiplex Intel Pentium 4, 2 GHz processor with 1 Gb RAM. Normal CPU usage on 96 KHz is 30% (Same average CPU usage with the standard sound card, Delta 44, used on this system) Both system use Windows XP. When switching to 192 KHz with the Edirol, the CPU usage ramps up to 100% in about 2-3 seconds and stays locked up there. I have been through all of the optimization routines that are recommended; I have been through the Edirol setup numerous times to make sure I haven't overlooked something, but still have the problem. Any suggestions are greatly appreciated. There is no mention whatsoever on the Flex-radio web site that a computer of this speed won't work with the Edirol, so I'm assuming I'm just not doing something right in the setup (yes, I am switching the Edirol and SDR-1000 to 192 KHz correctly).
