Sound on H616/H618 socs

[Stephen Graf]

@ag123, @c0rnelius, and anyone else that has interest in sound on these devices.

 

I have been able to put together a patch that enables audio for H161/H618 devices.  So far only audio on HDMI works. Analog audio is still generating an error on startup.

 

The patches were taken from a git repository by warpme:

https://github.com/warpme/minimyth2/tree/master/script/kernel/linux-6.6/files

, and probably came from the Zunlong SDK. A lot of the code was written by Allwinner.

 

@pixdrift generated a version of the patches for Armbian and I continued to work on them.

 

I have built a few images  and have a git repository if anyone would like to test, particularly on boards other than orangpizero3, on which I have tested.

If anyone has interest and skills to debug the analog audio, the dmesg errors are:

[    7.125509]  ahub_dam-snd-soc-dummy-dai: substream ahub_dam-snd-soc-dummy-dai has no playback, no capture
[    7.125539] sunxi-snd-mach soc:ahub_dam_mach: ASoC: can't create pcm ahub_dam-snd-soc-dummy-dai :-22
[    7.125780] sunxi-snd-mach: probe of soc:ahub_dam_mach failed with error -22

thanks, I'd probably try that some time. if audio for HDMI works, I think many users will be happy, I've read some comments some are looking for that.

currently, I'm using headless as wifi ap, so I did not know if it works.

analog may need to go back into h616 zero 2 to see how it is done there, maybe dts etc.

OrangePi has this analog audio figured out:

Yes I have tried the Zunlong images for orangepizero3 and they work.  Unfortunately those images are for a Linux 6.1 kernel and the zero3 and 2w were only officially implemented into linux with 6.6. The challenge is to get the Zunlong code into Armbian with the newer kernels.

Hi @Stephen Graf, thank you so much for these images. you are correct. Having audio even on HDMI is extremely useful.

Do you perhaps have the kernel headers for this image?

Also, Could you create an image for armbian jammy, or provide steps so that i can do it.

@SUPA Thank you for testing the patch.  I assume it worked and that you are working with an orangepisero3.

 

If you want to build you own images follow the directions in the Armbian build manual: https://docs.armbian.com/Developer-Guide_Build-Preparation/

and clone my repository. Unfortunately I have limited space on my google drive.
