Can I use my iPad as a second speaker for my Mac?

Sidecar works great for using my 12.9" M1 iPad Pro as an extended display on my 16" M1 Pro MacBook. Is it possible to use it as another speaker too? Is there an app available for this? I tried using Teamviewer and Zoom as a workaround, but there is a delay with Safari, and Apple Music just straight doesn't play.
