Dear penguin,

Just compile according to "Compile Ubuntu firmware(GPT)" directives and used ./build.sh. from cat /etc/issue getting "Welcome to RK3399 Buildroot". I tried 4K and as video there is no problem but there is no sound!!! it is not only for this video also when i test sound part, i coudnt get sound also. Do i have to chnage something? I didnt copy ubuntu18LXDE just used default rootfs for compiling. Do you have any idea.

penguin

Please use the rootfs in the official firmware to test.

"official firmware". Whichone and where can i download it? Also I used ubuntu18LXDE rootfs i saw 4K is so slow and also no sound. Then used debian linaro, couldnt download any package to play video. So which is the best solution for 4K with sound.

metind

I tried all. For  debian linaro rootfs there is no network connection. For other ubuntu rootfs images have same problem, sound ok but 4k video so slow. Is there any solution for it or am i doing something wrong?

metind
