[Freeswitch-users] hw:dummy not visible

Hi, I got a few more Skypiax questions. Please bear with me. 1) Skype should use hw:dummy as audio device. But where do I set this on Skype? In Options>Sound Devices, the only devices I see are; "Default device" and "hdmi". My guess was that alsa-utils or some other ALSA related lib would install this. But it seems this is not happening. Am i missing something? 2) To create the configuration directory, I connect to the FreeNX XServer running on my remote machine. I use NX to connect to the remote Xserver. I can start all sort of GUI applications this way. But when I try to run skypiax_auth, I get the following error message: "Cannot open X Display ':0.0', exiting". Any idea? Thanks again, Max.
