Mac Client Will Not Play Audio Anywhere But Computer's Internal Speakers

Moved over to a Mac Studio with an M1 Ultra chipset. Installed the Apple Silicon version of the Zoom client. The outbound audio will ONLY play through the Studio's internal speakers, even manually and automatically cycling through the available sources (USB external speakers, Airpods, et al). All other applications are able to see and use external speakers. Any and ALL assistance would be appreciated. Cheers!
