SDR Quest: Looking for Software Defined Radios for FreeBSD

Audio output is broken for this port.

To be honest I just posted an image to show that I was getting some output from my device.

I still haven't figured out how to get any audio output from sdr++ but have managed to listen to a station using a command line program

rtl_fm -f 100.9M -M wbfm -s 200k -r 48k | play -r 48k -t raw -e signed-integer -b 16 -c 1 -

so I should be able to get sdr++ working with some tinkering.

Under Module Manager, I don't see Audio Output. I only see Audio Source.

Its a weird setup. You want to choose from the dropdown in that settings area."Audio Source".
To the left of the dropdown is an empty box. You want to add a new device by Naming it in that box.
Its really an odd setup.. Look online for help. That's how I figured it out.

It still had really bad audio quality when I got it working compared to gqrx.

Can I scan for stations using rtl_fm ?
 
Your output for dump1090 is empty. No catching that signal or some problem.

No I had to use comms/dump1090 for the decoder.
