I have those installed on my laptop with the RTL2832U dongle. I have 2 portable radios--one DMR and one NXDN. My soundcard recording is set to Line 1-VAC, the playback is set to the laptop internal speakers. I do not hear the decoded digital audio in the speakers but I can hear analog audio in the speakers. I cannot see any audio waveform in the DSD screen. I tried to run Zadig.exe but the RTL dongle is not listed as a device although List All Devices is checked. I probably have several problems but would like to get this finally working. Thanks for all the suggestions.
