Sonar w/ FW-1884 and POD XTL

I can't help but wonder if the lack of any responses indicates that:

1) This works for everyone else that is using this configuration, or
2) No one else is using this configuration

If someone is using both FW-1884 and POD XTL (USB connection) together using the WDM drivers I would really appreciate a quick confirmation that this is possible with Sonar 4 PE. It works for me under Adobe Audition but still no success under Sonar.

Thanks,
Don

Thanks for the reply. I have answered your questions below.

Was the FW 1884 working fine before ?
ANS: Yes, and still does. In fact it works great even with the POD XTL over USB when using Adobe Audition instead of Sonar.

What settings do you have

No. of buffers etc etc for the FW 1884
ANS: I tried lots of different settings ranging from the default of 2 bufferes up to some totally ridiculous value. It works flawlessly with 2 x 256 except when using the POD over USB. Without the POD I can actually take this down to 2-3ms latency with ASIO and around 5ms with WDM. It actually ran with them set even lower but I felt like I was probably looking for trouble with it that low. I shutdown internet access, norton antivirus and software firewall when using the DAW.

Have you run the wave profiler for any WDM changes made.
ANS: Yes.

Do you have the FW 1884 linked to a PCI firewire adapter card (nothing else attached to this card) with a TI Chipset.. ?
Ans: Yes.

Have you tried the folks at the tascam forums. http://tascamforums.com/index.php?s=e3f99292602ef81607470b1f3e14061e&showforum=22
ANS: No but I have searched their forums. Since the FW-1884 and POD XTL work great together under Adobe Audition it doesn't seem like a TASCAM issue.

Also What are your system specs, ram processor etc etc ?
2.8GHz P4, 1.5GB RDRAM, 3 x 300GB 7200RPM drives with 8MB buffers - program and audio files on seperate drives.

If you are running Service Pack 2 then you require hot fixes for The Tascam.
ANS: All hot fixes applied. Again - works fine under Audition.

Since this works under Adobe Audition using the same WDM drivers with the POD XTL using the USB interface it doesn't seem like a TASCAM or LINE6 problem. It seems connected to whatever is telling the Sonar Audio Engine to shutdown. I certainly have options and can use analog from the POD until I find a solution. I just didn't want to waste any more time on this if it were a known problem. I like Sonar enough to workaround this minor issue. If someone else had this combination working I figured I would spend some time looking the magic settings.
