[hpsdr] Kiss Konsole no sound

[Georg und Brigitte Prin]

Hello,

I installed Kiss Konsole on my win7 system, but I didn't succeed to get any sound out of it. KK is working according to the frequency display, but does not react to the volume slider. The win7 seaker control within the mixer is fully open and the driver for the audio system is working properly.
Could anybody bring me on the right track?
