Pulseaudio to Dashboard

Hi, I am trying to get audio from a RTL SDR to be played on the dashboard. The SDR outputs different channels to different sinks in Pulseaudio. I would like to be able to mute/unmute each of those sinks on the dashboard, The audio should be played from the browser. Is this possible?

I’m still working On this but no luck yet

Is the dashboard accessed from the same machine where nodered is running? I think this is a prerequisite.

Unfortunately not, I basically need to convert pulse audio to web audio

Maybe I was too quick in my response.

  1. The following node can be used to play audio in the browser.
  1. Now you need to feed that node with the audio you want to play.
    Maybe this can be achieved by running the pulseaudio parec command in a node-red exec node.

  2. As I think that you cannot directly record from a pulseaudio sink you need to redirect first to a source. See following links:

Cheers :slight_smile: I will give it a go
