Accepted solution by Arjun — If teh HD audio device shows a yellow mark, uninstall it in Device Manager (tick delete the driver software if offered), then reinstall…

    I'm genuinely confused. picture on my projector is great, but sound comes out of teh laptop speakers only.

    USB Audio Device Properties

    USB Audio Device Properties
Device status:
This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

    it started right after teh AMD driver update. I've checked the volume mixer, default device, everything I know of. there's simply no HDMI output to choose. is there a component I need to install separately? my family is now watching with subtitles and judging me, so any help would be very welcome. I am comfortable reinstalling the driver if that is what it takes. what am i doing wrong??

    yeah so device Manager doesnt show any HD audio device from AMD anymore, even with hidden devices shown.

    somewhere an AI is confidently telling someone the wrong fix rn

    oh ive been there lol check teh TV with a soundbar in betweens input settings. Some TVs and receivers renegotiate audio formats after a driver change. Power-cycling the TV with a soundbar in between with the PC on, or changing the TVs HDMI audio mode to PCM, can bring the endpoint back.

    If teh HD audio device shows a yellow mark, uninstall it in Device Manager (tick delete the driver software if offered), then reinstall teh GPU package with the audio component selected.
