I just got the recent drivers for my audio card from Realtek and when I put then into Jackport Audio I get the following error message:

Assertion failed!

Program: D:\Users\brazg\AppData\Local\Programs\Jack\jackd.exe
File: C:\Users\letz\Desktop\Developpements\portaudio-21-11-2012\src\common\pa_process.c, Line 1558

Expression: framesToProcess != 0
Jack main caught signal 22

For some reason the audio device: ASIO::Realtek ASIO does this.
