I have a suspected bug that is making the Audio Track Mixer default to Touch mode, instead of Read.
This is troublesome because if a track is temporarily muted, a mute keyframe is added to the timeline. This requires navigating through the keyframe dropdown on each audio track, finding the track keyframe option, and finding and deleting all the mute keyframes.
If I have the mixer pabel open in my workspace, I can watch it switch back to Touch any time I click anywhere outside of Premiere, then back into the mixer panel.
The default should be Read, but no matter how many times I reset it, save my project, and save my workspace, I encounter the problem.
