I try to run wxCam through PulseAudio using the following command:

$ padsp -d wxcam

Although wxCam started ok, wxCam is been set to use xdiv format to enable sound during recording, but while recording the I get the error:

Cannot open /dev/dsp. Video file will be recorded without audio track

Please help me in fixing this issue. Below is some debug information:

$ padsp -d wxcam
