QUICK (BUT FATAL) UPDATE:
The message and problem got back on the next restart...
Customer support told me it is not possible to remove the message...
I'll keep looking.
Sorry.
Original answer:
I had the same problem till this afternoon. I updated the audio driver and the message is gone. Some research indicates it is a Samsung thing...
Anyway, how I did it:
Went to Device Manager by searching Device Manager on the task bar;
I opened the Sound, video and game controllers option;
Right-clicked Realtek High Definition Audio;
Clicked Update Driver Software...
It did the trick for me, so far...
I found solutions mentioning uninstall the driver and reset the machine. I thought updating would be similar so I did it and it seems to have worked.
