Galaxy S9+, Android 9
The Smartthings --> Audio Output section contains a Display Device as an output. Whenever a bluetooth headset disconnects, that becomes the default one instead of the My Phone.
As far as I remember it appeared there after first connecting to a TV and starting Dex.
Now I'm not able to get rid of it. (I'm not using Dex anymore, the phone is not connected to a TV via HDMI)
Anyone any idea? Thanks!
