You can check your kernel version with
uname -a
You can upgrade your kernel with
sudo apt-get update
sudo apt-get install linux-image-4.4.132-1083-rockchip-ayufan-gfd3f12ca5fae
and reboot
Thanks! I upgraded to the latest version at the moment (1087) and the audio started to work normally. Didn't remove the old kernel as it depends on a couple of other packages that, if that kernel is removed, would be removed on "autoremove" too, which seemed too dangerous to me.
Then I changed the timeout in /boot/extlinux/extlinux.conf from 10 to 3, and after a reboot, the RockPro64 stopped booting. I should had taken a look at its description first, because it turned out that it's in units of 100 ms, not 1 second as I have assumed (never assume anything!), and obviously 0,3 seconds are too short time for the timeout!
So I had to plug the microSD card again, turn the power on, remove the jumper after a few seconds, mount the eMMC module again, and fix the delay. This time I increased it to 30 (i.e., 3 seconds). Now the SBC boots from the eMMC module again. Unfortunately, it doesn't boot when both the microSD card and the eMMC module are installed, unless the jumper is inserted, in which case it boots from the microSD card. Also, it boots from the eMMC module only when neither the microSD card nor the jumper is inserted. And it's impossible to select the boot device only by inserting or removing the jumper when both the microSD card and the eMMC module are inserted. All the possible combinations are summarised below (S = boot from the microSD card, M = boot from the eMMC module, X = unsupported combination):
Code:
microSD eMMC jumper boot
0 0 0 X
0 0 1 X
0 1 0 M
0 1 1 X
1 0 0 S
1 0 1 S
1 1 0 X
1 1 1 S
Is this table correct?
Does extlinux show its prompt for the timeout duration to the serial console only, or also on the HDMI monitor? I can't see that since I have great trouble with the Vestel 22L1333G TV, which shows image only sometimes (EDID says 1080i interlaced mode is native, but it shows image only on 1080p progressive which I set after login with xrandr).
