VAC is needed for some systems if you want to both reroute the output to another program (i.e. decoder software).
There has been reports of sync problems with the VAC and hence using digital-analog-digital sound stream i.e. an extra soundcard for input may help.
If you do not get any output from the perseus software you do have a setup problem!

I have tried many times to use the Perseus without VAC.
The problem seems to be that the Perseus does not output to any sound card or dongle

What is the secret of your success ?

Hi Roelof, do you use the audio dongle to replace your headphone input instead ? 73 Marc Ede gld.

To avoid any problems, I went the hardware way!

This works like a charm and you can use as many as you have free UDB ports.

VAC's input to the decoder should definitely NOT resemble a square wave. With a signal present, input should look like a slightly "warbling" sinusoid wave pattern, depending on what you're trying to decode.
I guess something is wrong with Windows' mixer settings. Either the signal is to large (which will cause clipping, and square waves!), or way too small which can cause strange, hairy, spiked wave forms.
Hard to tell without more info.
