HDMI-1 doesn't support CEC by design. A/V should work on both ports without special configuration.

Did HDMI-0 ever worked with another OS? If LE is your first OS on RPi4, try RPi OS.

I've separated ION posts to provide more clarity, and more attention to this topic.

At your ALSA device list three devices have the same display name "HDA NVidia" (Analog, S/PDIF and HDMI). Seems like you or the system (naming confusion) have picked the wrong device:

Which output options do you have at LE's audio settings? Maybe the wrong output device is currently selected.

Make sure that all your firmware is up-to-date. This can be challenging, because you probably need Windows for that.

How do you script a daily graceful shutdown schedule in LE ?

LE has cron service. Use our search function (magnifier icon) for details.

So you own an Acer AspireRevo R3610. Specs say it's an nVidia MCP7A-ION. I think that's the "audio chip" in this case.

Thanks, and wait for chewitt now.

Sadly, in my case the audio problem continues to present itself with no resolution.

Can you say something about your audio chip? Or open the box, and make a hi-res photo with all chips. So you and chewitt could compare ION hardware.

To me it looks like the driver doesn't offer any usable sample rate:

chewitt Which sample rate is in use on your setup? Maybe your setup can play an unusual sample rate (40800Hz, see log snippet), but the setup of paperbackwriter can't.

Try LE 12 Beta. If the issue persists, try without DRM Prime (gear icon menu at playback bar).

I'm running LE 11.0.6 on Raspi 4. Does this procedure works with the current version ?

Yes. Eventually you have to overclock for higher resolutions.

Quote from necktwi

how did you come up with these delay values? did you do it manually or sufficient delay on fastest sink device will sync them?

That's usually a trial-and-error thing, because precise delay time is unknown for most parts of the signal chain. So you eventually have to adjust delay values for your system.

AI has a tendency to mark all unknown stuff as virus. Just ignore.

Since LE 10, HDMI options have been moved from config.txt to cmdline.txt.

1. Login by SSH, and open the file cmdline.txt. It works similar to config.txt.
2. Append vc4.force_hotplug=1 to the end of the line.
3. Store that file, and reboot.

LE12 is not available to download, I only find LE11.0.6

https://test.libreelec.tv/12.0/Generic/Generic/

Yes, try without that USB switch, too.

Try without Bluetooth devices.

nopb01 As mentioned in the link, post a log from latest LE 12 Generic-Legacy nightly.

Q2: Generic-Legacy uses X.org for graphics. X.org doesn't support HDR. Generic LE supports HDR.

Thread renamed and moved for Q1, because it's very likely a Moonlight issue. To know for sure...
