Catalina - wrongly recognises my external speakers as Digital Out; no sound
Recently updated iMac to Catalina; now system recognizes my external speakers and earphones as Digital Out, and type as Optical digital-out port, and there's no sound. Any advice to fix this, please?
Internal speakers work fine.
External speakers work fine on MacBook (Mojave), where they're recognised as external headphones on headphone port, which was what the iMac used to recognise the speakers as previously.
