Adding to this, the audio chat notifications only work if you do not have the Chat tab opened. If the Teams window is not in focus and on the Chat Tab, audio and toast notifications do not display.
By switching to any other tab, the Audio and toast notifications will play.
Thus, my very dumb workaround is to just switch to the Meetings Tab when I walk away from my computer but have my wireless headphones on, thus ensuring I at least hear a ding when a message comes in.
