HDMI audio solved

[fczuardi]

Updating this thread since it is the first google result for "rockpro64 hdmi audio"...

In my case I had to change my kernel to 4.4.138-1100-rockchip-ayufan-g95cecee47f40 to finally make HDMI audio work. Many other kernels were just emitting a high pitch cricketing-like sound and slowing down videos.

To get the image with the good kernel you ca use:

Code:

sudo apt install linux-image-4.4.138-1100-rockchip-ayufan-g95cecee47f40

And then use the change-default-kernel.sh script to select it:

Code:

sudo su
 . /usr/local/sbin/change-default-kernel.sh
reboot

If your /usr/local/sbin don't have the change-default-kernel script, you can update to the pre-release train by uncommenting the line on /etc/apt/sources.list.d/ayufan-rock64.list

then:

Code:

sudo apt-get update -y
sudo apt-get install linux-rock64 -y
sudo apt-get install linux-rockpro64 -y

yay! sound!
