Does the sound output through line-out? If not, it is planned?

Nope, no sound output right now. It's a great idea to add though, but I probably won't be able to get around to it in the near future. If someone wants to take a look I think the easiest approach is to just use Python's subprocess library to call the rtl_fm utility (which should be installed when rtl-sdr's software is compiled and installed). I don't think there are any proper python wrappers around rtl_fm so calling it to run as a separate process is probably the easier option for now.

I'm currently adapting this for a quick project at the Royal College of Art in London, it'd be great to implement sound on something like this.

Has there been any development or possible solutions in regards to sound since 2014?
