Unable to add a second audio input source #2143

Closed dforsi closed 3 months ago

dforsi commented 3 months ago

I have two sound cards (one is builtin on the motherboard of my PC and the other is embedded in my radio), I can add an audio source and select either one. I would like to add both as separate sources for differente demodulators, but the sampling device dialog allows only to add one audio source.

Probably due to the way the Audio plugin is handled as if it was an actual hardware device. This does not happen with KiwiSDR for example.

Issue is here: https://github.com/f4exb/sdrangel/blob/master/plugins/samplesource/audioinput/audioinputplugin.cpp#L96 it should be listed as a "BuiltInDevice"

Conversely the audio output plugin is correctly listed: https://github.com/f4exb/sdrangel/blob/master/plugins/samplesink/audiooutput/audiooutputplugin.cpp#L91
