Windows 10: Windows 10 HDMI audio through second monitor

I have two monitors, one connected through displayport, one connected through HDMI. The second monitor has speakers connected to it and is used as the sound output, this is set as the default sound device NVIDIA High Definition Audio. The monitors are used as extended displays next to each other. I am on the latest version of WIndows 10 as at June 2020 and the hardware troubleshooter reports no issues. Sound works fine when the computer comes on.


My issue is that if I leave the computer and it goes onto the screensaver or the power saving mode monitor switch off, when I come back to the computer the sound has gone missing - I get no sound. There are two workarounds for this, either reboot the computer, or go to display settings, change the monitor situation from "extend these displays" to "show only on 1", say "keep", then set it back to "extend these displays" and click "keep". The latter seems to reset the monitor situation and the sound comes back.


Windows 10 is not handling the screensaver / power saving situation with multiple monitors and HDMI sound. Please fix.

HDMI to DVI Monitor Will Not Play Audio

Thanks for the suggestions, Deepika. I have a Samsung SyncMaster HDTV monitor and a SHARP monitor. I'm trying to get audio on the Samsung HDTV. I'm not sure if you need an audio cable when connecting to the HDTV. Anyways, I kept it on the television. Either
way, it doesn't work. I ran the troubleshooter, and there isn't any problems. I tested all the cables yesterday, and everything works as usual. How are the HDMI cables supposed to connect and work with video and audio? Is there a driver problem? I believe
it might be because my monitor is in the DVI port, instead of an HDMI. This is why it's not detecting on the sounds/playback devices. Plugging an audio cable in the secondary monitor with VGA works, but using an HDMI for the television does not. Using VGA
for the television does work with audio. Not sure what the problem is, or if I have to plug the audio cable in the HDTV at all. Any help would be appreciated! Thanks!

UPDATE: Figured out the problem, testing. The HDMI cable although supports audio and video, the DVI connector
does not. Because of this, the computer detects it as a DVI connection. It instead uses the regular audio cable. The television, however, does not. It detects HDMI first, and uses that as as the audio. Since there is no coming through the DVI
connector and instead coming through the audio cable, it won't play anything. This can be half solved by changing the source device (source>edit name) on the Samsung television to HDMI DVI. This, however, does not fix it, as sound still doesn't come out. The
computer still has to be changed to be able to play audio properly. Any suggestions on how to fix this?
