I’ve scanned through multiple .ini files and not had any luck pinning down an option for keeping the game audio on, while the client is in the background. I don’t have a job and am not playing at work, so I don’t need to get all stealthy when I minimize Conan or open the wiki for a recipe.
What I really dislike is not hearing when a purge kicks off, or the next shower of starmetal.
Beyond that, I love my forest base on Siptah so much, for all the fantastic ambient sounds. I actually would load the game in background to just listen to those sounds while I do other things on my computer, like taxes or reddit browsing.
