@guidolI wasn't able yet to try out the 5.9 kernel. I tested the dts file you posted as a dtb file on the present (lower) 5.8 kernel and found out it doesn't work to activate analog sound. aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sun50ia64hdmi [sun50i-a64-hdmi], device 0: 1c22800.i2s-i2s-hifi i2s-hifi-0 [1c22800.i2s-i2s-hifi i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0

Great, Guidol! Thank you very much for this good news. I wil try it out! Thanks for the one that solved the problem.

This shows cards are detected on the kernel 5.7.15. dmesg|grep -i sound [ 8.338780] asoc-simple-card sound: sun8i-codec-aif1 <-> 1c22c00.dai mapping ok [ 9.015640] asoc-simple-card hdmi-sound: i2s-hifi <-> 1c22800.i2s mapping ok

HDMI-audio however now works okay, as you said Guidol.

On my nanopiA64 the analog sound is completely gone after the recent update, not even static noise, although there are cards detected. I lack coding skills, but I have a hunch it has something to to with the dtb-file.

mpg123 worked indeed! While mpv gives static noise. You are right!

Indeed I think it's a pulseaudio problem. The terminal-commands given resulted in "command not found" on my system. mpg123 was not installed on my system. The packagemanager suggested mpc123. I installed that, but using it with your commands resulted in a lot of errors. I wil also search further to find a clue. Thank you allready! You have come a long way and it's a very usable Armbian-install.

Yes, that is the situation in this nightly automated build ..

HDMI-sound however works as it should

These are the contents of my alsamixer ...

I am afraid AIF1 DA0 and DAC are not present in my alsamixer. I looked at the controls in alsamixer with the analog soundcard and pressed ALL (F5). A lot of controls (headphones for instance) but not those ..

Sound is included and detected. The .dtb file also shows the correct value for the soundcard as mentioned in this thread. I hear a lot of static noise and on the background I thought to hear some distant music. But that may be my fantasy playing tricks. **** List of PLAYBACK Hardware Devices **** card 0: sun50ia64audio [sun50i-a64-audio], device 0: 1c22c00.dai-sun8i sun8i-0 [1c22c00.dai-sun8i sun8i-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: allwinnerhdmi [allwinner,hdmi], device 0: 1c22800.i2s-i2s-hifi i2s-hifi-0 [1c22800.i2s-i2s-hifi i2s-hifi-0] Subdevi

Due to the circumstances I wasn't able to spend more time in this issue. But today I found some time. Bought a fresh sd-card of good quality and downloaded the Buster Desktop from the automated build on the frontpage. Actualy it is not bad at all. The system is very responsive only sound doesn't work. The cards are detected as before. CPU-Temperature is at 37 degrees celsius. The allwinner-chip doesn't feel to hot either. I will continue using it for a while to try it out. But apart for the sound it feels very usable.

My sd-card got corrupted unfortunately. Currently I am using the pine64 Armbian-image from 10 jan 2019 with frozen kernel && firmware, etc on the nanopi-a64. With this image everything works as it should, sound and everything, except for the ethernet. I've got Wifi however ..

I followed your advice and used the sun50i-a64-nanopi-a64.dtb_7nd with the nanopi-a64 5.4.33 image. CPU-temperature is now a steady 52 degrees Celsius. Sound is still wrong, a kind of sizzling while is has the correct value in the dtb file (simple-audio-card,mclk-fs = < 0x80 >).
