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?

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

Maybe I was too quick in my response.

1. The following node can be used to play audio in the browser.

> **[node-red-contrib-play-audio](https://flows.nodered.org/node/node-red-contrib-play-audio)**
>
> A node-red node for playing 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:
