Traktor LE2 with Behringer BCD3000 config. problem

Hey there,
I've bought myself a Behringer BCD3000 MIDI controller which is available for a couple of years allready and which includes a free Traktor LE Software.
In general everything does work like it should but just as long it's running with the onboard soundcard of my notebook.
If I set the audio device to "BCD3000 ASIO" or "Behringer BCD3000WDM V1.3.4.0 (WASAPI shared mode)" the currently running track is beeing played in slow motion, though there is no output signal coming wether from the notebook or the MIDI controller.
I've allready installed the recent Win7 driver from Behringer and I tried Asio4All as driver as well, whithout success.
Same problem with wirtual DJ and the former LE Version as well...
Does anyone have a clue what the problem with the driver or settings could be?

thx very much
cheers Stefan

 

Please optimize your system. disable wlan, antivir, firewall, disable the energy saving option in the usb root hubs in the device manager. AND, set the energy options to FULL PERFORMANCE, this may be the problem.

 

Please use only the ASIO Behring driver, no ASIO4ALL or the WASAPI!
Adjust the latency according to your system performance and do everything Mikesilence wrote.
+ disable the ACPI Battery Mode in Windows!
