Just upgraded from Audirvana 3.5.46 to Audirvana Studio 2.8.2 on my new PC running Windows 11 Pro.
When looking for a specific track in Search Menu, I find no way to add it from the Search Menu to currently playing Play Queue (Right-click?) like it was possible in 3.5.46.
Workarround is to click on “See all”, then Right-click then “Add to play queue”.
This is something we have been pointed out by users, and we need to improve it. For now, the behavior you describe is how it behaves nowadays, but we want to change it in the future.
