Adobe audition and Sanoma 14.2.1 - I can only record the left channel. The right channel is inoperative as it it not receiving the feed from my Focusrite 2i2. This works ok in Logic Pro and Audacity but not Audition
We need to see two things, really. The first is your Audio Channel Mapping page in Edit>Preferences, and the second is a little more information about how and what you are recording. Waveform view or Multitrack? If it's Multitrack we need to see what options there are available from the Focusrite. Chances are that you've selected a [m] option to record with, which would only enable a single channel anyway. And what source are you using?
I finally found out the issue. It was to do with Apple's Voice isolation on the microphone.
On any Mac after 2018, when you open a programme that uses a microphone a mic symbol appears at the top of the computer screen. This need to be set to Standard and then everything reverts back to being able to record on both channels separately.
