AUDIO low latency streaming

looking for a solution to stream just AUDIO with the PEARL2

Single channel audio
If a single channel is all that is needed, then a single Instreamer can be used:
• Configured to multicast to the Audio Signage App’s default channel:
• Input Source: Line Mono
• Audio Format: PCM / 24kHz 16bit mono little endian
• Streaming Mode: send always
• Streaming Destination:
• Connection Type: RTP
• IP Address:
• Port: 4444
• Connected to the audio source

Unfortunately the Pearl2 cannot stream out just audio, it will always stream with a video track also. You can make the video of a low resolution, framerate and bitrate though if all that really matters to you is the audio.
