I am facing a strange a rather annoying problem since the time I installed RTM version of Windows 8 Pro.

I have a habit listening to my favorite music in iTunes on my PC which feeds Audio to Onkyo HT-R380 receiver via HDMI cable and another HDMI cable connects to my Samsung monitor (Samsung monitor is the main display).

The power options are default:

Now the problem: I leave the computer while continue to listen to music. But after 10 min, the Samsung monitor display turns off as per power options. But the music also stops at the same time.
I almost broke my head to solve this but it's been bugging me for last 2 months.

I have Nvidia GeForce GTX 670 and I tried all the Windows 8 X64 drivers released so far by Nvidia. Currently on latest WHQL 306.97.

Any help why music stops when screen goes blank?

PS: This issue never happened in Windows 7

Under your power options, do you have the balanced, high performance and power saver options like 7 does?
I only ask as it might be worth setting it up to high performance, then trying to change the monitor and sleep options :)

edit
Also are you using desktop speakers?
Some Samsung monitors I think come with built in speakers, like my hp and acer monitors do, and before I bought my desktop speakers, and ran my audio to them. (when my monitor went off due to those settings, the sound went as well)

^^ Doesn't work under high performance as well :(

No desktop speakers nor does my monitor have internal ones. it's Onkyo 5.1 HT system.

Does it happen if you use something made by Microsoft to play your music?

I have removed WMP and Music app as I don't like too many apps doing same thing to clutter. I will try installing WMP. But iTunes does all sync and all with phone so it's the main audio player.

Edit: Same happens in WMP or Music App. :(

Clarify. Is the monitor in question connected via HDMI or DVI?

Monitor is connected by DVI and Onkyo & TV is connected by HDMI.

Here is a video of the problem.

The only thing I can think of is the Nvidia drivers. Do you have NVIDIA HD Audio Driver installed in your Control Panel list?

If you haven't already tried, uninstall it, reboot, and see if anything changes. It is automatically installed with any driver package downloaded from Nvidia's site, so it's not like you can't un-do getting rid of it.
