BUG - Audition 2019 plays stereo tracks in mono, and now Audition 2018 and Audition CS6 have this problem
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)
