as I wrote in this thread before, my last working commit with hdmi audio was 5e44eaf. the next commit successfully built 04373a4 hdmi sound no longer worked. The reason is the same, it is initialized twice. in the 93e4029 logs, the only thing that changed was RTL8812AU (sources from 93e4029 are not available) and added a dump_stack() call; at the beginning devm_snd_soc_register_card ( sound/soc/soc-devres.c ).
there are traces of double initialization in kodi logs

hi.

Can you advise why hdmi.audio can't initialized?

LibreELEC release: A20.arm-devel-20230616153248-93e4029 latest A20

Try another recording program. I used just dd on linux and

In general, everything is bad with the A20 in LibreElec RE: Support for A10/A20 .

cb2 as a mpd client on OpenWRT for playing music, this is an overhead. a TP-Link pocket router is enough.

I don't need 4K, my internet won't provide speed. I was counting on 720p, 1080p. YouTube worked great. The plan was to try nes / snes / sega. Lakka also does not support A20 because the parent project does not.

about hdmi-audio

b1e43da work

5e44eaf work

04373a4 not work

5a56803 not work

looks like i find a reason. but i not familiar with git and i can go wrong directions

if anyone is interested. built some images, reduced the range

71f490b hdmi-audio work

0d15a6f hdmi-audio not work

sad news

we can bury our cb2 boards.

Old, crap stock android 4.x. Armbian - non official supported. I try Lakka, but it even not boot. LE is the best that i try.

7 years for kernel support - hw decoding and hdmi-audio. No one have time and want to fix code for old chip support.

When and if there is a volunteer, the A10 / A20 will fall further behind technology.

you can try delete .kodi folder. be sure to make a backup

not too much comment after LibreELEC-A20.arm-9.80-devel-2f50060

I can build only 2 days in 2 weeks. can test 2 weeks.

I can try different images to localize the problem. There is no way to build images
