Can't connect to external audio TaoTronics TT-BA07

[Albert Cardona]

From my iphone and chromebook I can see the external speakers plugged to a TaoTronics TT-BA07 bluetooth device.

But from Ubuntu 20.04, the device doesn't appear listed in the settings. There is listed a deviced named "1" that, when connecting to, appears to be a sound device, but from the sound settings "test" buttons I can't get any sound to play.

Any hints as to how I could triage this issue and collect more details?

Looks like an aptX device, which Ubuntu doesn't support audio on yet. But that should not prevent pairing...

[vlc (r-a-ndylxr)]

bluez (5.59-0ubuntu1) still has this problem
