I have installed AirSpy, VB Cable and DSD+ on my Windows 10 operating system. I checked to hear any normal audio signals using AirSpy, and I could perfectly hear the local HAM repeater. I then tune into a frequency having a digital transmission on Air Spy, and I pipe in the audio to VB Cable Input.
I use the below command to start DSD+
---
DSDPlus -i2M -o1M -fa -e -O NUL
Below are the status messages which come on the console
=======
DSD+ 1.101pt

I understand that DSD+ would read sound from the CABLE Output and ideally should push the processed audio to my laptop speakers. How ever, when a digital signal is received;
1. I see the wave form changing based on the audio signal
2. But I do NOT hear any audio (processed or unprocessed) on the laptop speakers. The DSD+ console also is not throwing up any more messages indicating that it has received an audio input and identified the digital mode.
I am new to this; so request any expert to help me. Have I missed out any step?
