Issue description

On default installation HDMI sound don't work unless I choose hdmi device ( ROCKCHIP-HDMI0HDMI/DISPLAY PORT )
See issue: #8598

Now, when streaming my PC through moonlight the audio is delayed.
I don't know if related or not, but the issue don't happen with other OS on Orange Pi 5 (including Android image)

Any tips?

Also, what the kernel version in v40?

Detailed reproduction steps

Fresh v40 on sd card, with moonlight installed & paired to local PC through wired lan.

Currently there is no hardware acceleration for the rk3588 boards. We would need to patch in support somehow.

Thanks for follow up.
I tested it, the delay actually system wide, with every game (only tested moonlight earlier) now I tested the free installed game. There is still delay.

I think it related to how it handle sound in HDMI, since out of the box auto doesn't enable sound in my TV (TCL).

Side note: since this is kernel 6, can you includes new drivers for some WiFi 6 dongles? specifically for me ( chipset: mt7921 , ID 0e8d:7961 MediaTek Inc. Wireless_Device ) it does not work yet.

Other orange pi 5 Ubuntu desktop distro like

Support it, how can I inject the drivers? Possible?

my rk3588 boards don't have these delays you're talking about, at all... maybe your tv needs some sound calibration.

I currently have 2 os (Joshua Ubuntu 24 on m2 & Batocera on SD card) both supposedly same kernel (6.1)
Removing sd card & rebooting to Ubuntu with everything as it is, zero delay on Ubuntu.
But as you said earlier it may relate to hardware acceleration since maybe my TV add something to the mix like some audio codecs that need to be disabled so the TV ignore it.

I need more time to check tv settings, I'll update if I knew something.
