If you're on a distro which has migrated to pipewire+wireplumber, the available and active bluetooth profiles can be discovered with something like:

  pw-dump | jq -r '.[] | select(.type == "PipeWire:Interface:Device" and .info.props."device.bus" == "bluetooth") | .info.params.Props, .info.params.PropInfo'

And by default, wireplumber will enable all of the codecs it has been built with [https://pipewire.pages.freedesktop.org/wireplumber/configura...].
