Audition 2019 properly displays stereo tracks (Wav, mp3, m4a etc) but my computer's audio system is getting a mono-ized 2-channel feed (i.e. both stereo channels receive a mono signal). Until the latest Audition 2019 update this was not a problem with my earlier installations of Audition 2019 or Audition CS6. But they now have been contaminated by this bug.

But when I turn on my Bluetooth headphones and switch Audition to output through the Bluetooth audio interface, stereo IS preserved. This would not be a problem except for the limited playing time of Bluetooth headphones, few of which could last through an all-day edition session.

My computer system's audio system is Realtek High Definition Audio)
