Which node is used to play mp3 to a network player

I am moving my Node-RED from a HomeAssistant (HA) installation, to a stand-alone Node-RED on a Synology.

In my HA, it has automatically found my network's speaker (BlueSound) works like Sonos.
Thereby I could easily play an MP3 file and point it to my Entity (MediaPlayer)

Now I want to be able to do the same, but outside of HA, so my question is:

  • What would you recommend of Node that can be used, if I know my IP for my Network Speaker and will be able to change Volume etc. and play a local MP3 to it.
    Again it is NOT a Sonos.
