ok so i'm genuinely confused. picture on my TV is great, but sound comes out of the laptop speakers only.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
it started right after the AMD driver update... ive checked the volume mixer, default device, everything I know of, theres 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, sooo any help would be very welcome. I am comfortable reinstalling the driver if that is what it takes.
