Z270 Pro Gaming Carbon - HDMI audio in - stopped working

[rayboy_destruct67]

Hello, just 5 hours ago I turned off my computer and everything was working fine. That is, my vizio sound bar was plugged in using 'HDMI in' to my Z270's hdmi port. It worked fine for 2 weeks prior to this as well. Now i've booted up the computer and it will not detect the sound bar anymore. Before, it would use to say 'Vizio' under devices in the sound manager. It's now completely gone and I don't know how to get it back. I've tried installing my old drivers and no dice. Unplugging, replugging, rebooting pc numerous times, changing PEG to IGD etc, can't get anything to work. Any help would be greatly appreciated.

Check your device manager do see if you have onboard audio issues. That is most likely providing the audio for HDMI
