Must be your audio settings. Make sure you set it to 2.0 channels.
Many thanks, that was the problem. Is working perfect now. 
Great!
Are the 8K 60FPS videos playing well for you? On my device I had issues.
With todayās Nightly finally Iāve got gigabit:

Huh? Strange
On Android always had gigabit, so I think it was a CE (maybe dtb) issue. I don"t know.
OK, something strange with this device with CE,

Just wanted to give some info to those with ethernet troubles, about an experience I had in the past with Mecool devices (not Beelink but problem might be more widespread).
Very surprisingly, the ethernet connection quality was dependent on the BRAND of router. My device had good connection when connected to Asus and Netgear, bad connection when connected to Linksys and TP Link.
Just saying for those with ethernet problems to try different router brands if that makes a difference.
You may be right that some routers may work better with some equipment than others, but I think that itās crazy to ask someone to replace their router just because a single device is having issues with it.
Itās a problem with the device, not the router.
I agree and N2 doesnāt seem to have any issues. And supposedly they use the same chip.
I think there ist a mode change problem or graphic chip reset problem. The 8k 60 frames plays smoothly and fine without stacking if I do not play a lower resolution before and afterwards. If I had played a lower resolution in the meantime and then the 8k Video stacks or shows only pixel mix without any picture. 4k Videos are playing fine all times. Only after reboot then the device plays the 8k 30/60 videos fine again. Sorry for my bad english.
For me with 1Gbit box is almost unresponsive with Asus and Huawei routersā¦ It possible that it was some defect in early boxes.
As boot2k3 said it was tested in multiple routers. Iām still trying to break mine (for testing purposes) that has, at the moment, gb ethernet.
Do you know why CE doesnāt boot in full HD if android display setting is 4K ?
Both resolutions seems correlated in boot, if android is in 4K and CE in 4K CE boots.
If you are on last TheCoolest image, than try today nightly image.
thanks, Iām using your workaround and the last nightly (0710) and Iām unable to reproduce this issue.
Hello, i have tried mount emby server on this box.
First, installed it over docker and i get this error: docker: Error response from daemon: unable to find ānet_prioā in controller set: unknown.
Then, i have installed emby4 addon (the installation is correct) and i can not access by web (ip:8096).
Anything to try?
Until now I am still confused, and I have downloaded the nightly version of CE. Which question is my dtb for my GTK?
Check the device_trees folder on the card and Iām sure you will figure out which dtb is yours.
Saya sudah banyak mencoba dari device_trees, tapi selalu gagal boot. Bisakah anda beri tahu saya yang mana untuk merubah menjadi dtb ?
