Print the LDAC adaptive bit rate adjustments 

A2DP LDAC State:
  ...
  LDAC quality mode                                       : ABR
  LDAC transmission bitrate (Kbps)                        : 990
  LDAC saved transmit queue length                        : 0
  LDAC adaptive bit rate encode quality mode index        : 0
  LDAC adaptive bit rate adjustments                      : 4

Test: A2DP streaming to headsets that support LDAC
