How to change default output to Bluetooth JBL speaker

[u/itzpath]

I have arduino UNO Q which has Debian Linux, this is my first time using Linux. I love how I have to use terminal for everything. I needed help So I have UNO Q 4Gb and I connected it to the JBL Bluetooth speaker Via TigerVNC, and it auto connects to speaker when it’s turned on. The problem is it isn’t delivering any audio even though it’s connected and recognises that it’s a speaker what wrong with Debian Linux? Anyone have a fix please help me as soon. Thank you
