As I am capturing low quality radio audio, single mono channel with a low MP3 bitrate of 64Kb/s is more than adequate. We will transcode the audio to MP3 as the format is well supported by web browser and audio clients. The capture device is ‘alsa://plughw:1’ for capture from card 1.

VNC or RDP either don’t support audio or just did not work. It took more than remote desktoping to make this possible. My aim was to listen to the radio on a remote Raspberry PI hooked to a RTL-SDR dongle.
Sometimes it is necessary to stream the system audio over the network.
