Problems with Java Media Framework (JMF), Sip-Comunnicator

[jamesDothellboy]

Hello,

I'm a little frustrated. I tried now for hours to run the sip-communicator. It ends up with the following errors

Failed to realize: com.sun.media.ProcessEngine@1d592a
  Cannot build a flow graph with the customized options:
    Unable to transcode format: LINEAR, 44100.0 Hz, 16-bit, Stereo, LittleEndian, Signed
      to: gsm/rtp, 8000.0 Hz, Mono, FrameSize=264 bits
      outputting to: RAW/RTP

I figured out that this has something to do with the Java Media Framework, which is installed. So I played a little with JMStudio.

But this dosen't work, too. It doesn't matter which sample rate i chose. I always receive the following message.

Exception in thread "JavaSound PushThread" java.lang.IllegalArgumentException: Illegal request to write non-integral number of frames (22050 bytes )

The only audio device I can chose is the JavaSound audio capture.

I'm logged in as root.

I don't know how to solve this problem. So I hope someone can help me with that?

Thanks,
