I'd like  some help on this issue (sorry if it has been answered elsewhere). 

Pretty much like it says in the title. I use a TV connected to GPU via HDMI 2.1. Whenever I leave MSFS open for a while, and the TV goes to standby, the sound is lost when I return. This doesn't happen with other apps e.g. Chrome. 

Does anybody else have this? Any solutions? Sometimes I don't feel like restarting the sim when doing several sessions the same day, as it takes so long to start. Or perhaps I just want to take a break from a flight and come back. Can't because the sound is gone. 

I'd check if the input port is set to shut down on inactivity. Also look at your power profile in Windows to check if anything is set to time out after a bit.

You can also try changing the assigned audio output device in the MSFS Audio settings. Sometimes, switching to a different output device and then back again can restore the audio output.

I have MSFS set to the output that I use, which is LG TV via Nvidia High Definition Audio. When the issue occurs, it resets to system's default device. I also checked if there's anything in power settings (control panel), but all power saving features are pretty much turned off. 

It's strange - whenever MSFS looses connection with my TV, it cannot be restored in the same session.

Sorry, I didn't quite understand this. The HMDI connection?

I may be miles off here, but if Windows is set up to not shut the screen off due to inactivity, then wouldn't the issue be within in you TV's settings?

Apols if I've misunderstood.

As I see it you have two options. Either set the TV up to not turn off after sitting idle, so that the connection is never lost, or you can set the TV as your default output, so that when it disconnects and switches to the default, it is right back to the TV.

I think the way MSFS is programmed, it will only bind to an audio device at startup.  So if a device it has bound stops responding, MSFS is mute until restarted.

So, as recommended above, make sure both ends of the connection remain active--no suspend enabled on the PC side, and no auto-standby on the TV.

Are you using the TV speakers as your only sound source?  Or a set of external speakers connected to the TV?  Not sure what I am reading in your posts.

It's the OLED TV that shuts down. Which is a good thing, to reduce the risk of burn-in.

The TV is set as the audio output (or rather the "Nvidia high definition audio" via HMDI) both in MSFS and Win11 settings. I prefer not to disable the auto-standby function on my OLED.

I think you're right Bob.

My audio setup is as follows: Windows 11 => 4090 (Nvidia high definition audio) => HDMI 2.1 => OLED => BluSound PowerNode amp => surround speaker system

Thanks for all the inputs! It's a fringe scenario, as I'm using an OLED panel which should not show a static image for extended periods of time. Perhaps the solution might be a good old Windows 95 screensaver? 😅

Is any of that USB controlled?  If so you should take a look in Device Manager at device properties to see if any related are under the influence of Windows Advanced Power management.

No. Good suggestion though. I browsed through device manager, couldn't see any power saving features. 

Does the AMP have HDMI in/out?  Why not reverse the order and go 4090-amplifier/surround sound-OLED?   Then your OLED could go into standby but audio would still play through the amp.

Why you would want your screen to power own "during" MSFS is the part I don't understand...   It's not a static image there is constant movement even if the panel depiction is relatively static.

Yeah, I thought about that when I was checking the connection. I'll see if it's possible to run sound through amp first, then TV.

I can't have a static image due to burn-in risk. Even at MSFS menu, or aircraft at gate, the risk is too high. 

It'd be relatively easy to write a Lua script that slowly cycles thru different view presets to keep a static image from burning in.

The thing with OLED screens, though, is that burn-in is occurring constantly.  So-called "image" burn-in results when a static image is on-screen for prolonged periods because it disproportionately wears down the same pixels on the screen leaving a visible shadow, rather than wearing down the pixels more or less randomly.  But any time an OLED screen is on, the organic pixels on the display are slowly degrading.  So the ideal, IMHO, is to turn the screen off when not in active use to preserve it.

Also, the pixel degradation is cumulative over time, so if you leave the screen on, for example, the MSFS menu or a forward-looking panel view for moderate periods repeatedly, those pesky shadows can still start to appear out of the fog...

This gradual image degradation on OLED panels is a large factor in why I opted for a 38" LED 21:9 display rather than a larger OLED one when looking for a new monitor during the last Christmas season.  Hardware G-Sync was the other deciding factor.

I have a LG OLED Monitor have you looked in the settings.

Running windows 11 I have the taskbar set to auto hide and all my start shortcuts are pinned to the taskbar not on the screen. when it sleeps it goes through a cleaning screen mode with the onboarded CPU.

The same happens now to Samsung as they use LG OLED panels rebranded, just like third party do with GPUs that Nvidia supply.
