Default pro 2020 scanner and Unitrunker 1.0.32.7

Just for something to do today, I hooked my old Realistic Pro 2020 with a discriminator tap and with a cable hooked the scanner up to my line-in in my computer. I started up unitrunker version above and locked my scanner on the control channel to decode Apco 25 signals.

Everything seems to be working, I can see the talk groups and the ID's popping up but I don't get any sound except the control channel even with it in mute. I am using VB Cable to send the signal to DSD 1.74 but no scrolling.

Just wondering if anyone else has done this and if so maybe give me a pointer or two.

So with the setup using signal receiver, I take it that I will only be able to decode the Target, as nothing comes up with the Source.?

Need some help this is getting frustrating, still no sound, everything is working just like if I was using a singal RTL-SDR just no sound.

I have used the same sound setup using SDR Sharp, VB Cable to DSD1.74 and that works good, just not with a discriminator tap. Any ideas, I have used the instructions in the above link, thanks unitrunker, but no joy. Any help would be appreciated.

Thanks
