Thank you very much for all your work! I watched a two-hour long movie tonight and I can confirm that the audio is perfect at 44.1 kHz and 24 Hz refresh rate.

jernej I've been testing the build more thoroughly and I've found some interesting things and a workaround to fix the sound issues.

The first thing I tested is playing a video at 1080p 60 Hz. As always, the problem is still there, even with the interface sounds. But then I decided to try at 1080p 30 Hz. I played a YouTube video and found the sound issue to be completely gone, but when trying with a movie the sound started to cut off again. This was already reported by other users. When tweaking the sound settings, I found the culplit: when limiting the audio sampling rate from 48 kHz to 44.1 kHz, the problem is completely gone for every video. That's why YouTube was working before, because its audio sampling is 44.1 kHz.

The rest of the audio settings doesn't seem to affect anything. I then tried 1080p 60 Hz with the audio sampling limited to 44.1 Hz, but the audio cuts off again. So to sum up, I think there are actually two different sound issues:

- When using 1080p 50 or 60 Hz

- When sending a sampling rate of 48 kHz or more

Maybe this information helps you solve the problem. For now, I can use 1080p 23.98 Hz and 44.1 kHz to watch movies. patrickkfkan shahidali55 you could try this too, maybe limiting the sampling rate also works at 60 Hz on your TVs.

jdpc patrickkfkan Another update to test: libreelec-h3.arm-9.80-devel-20190917173122-d52e8dc.tar If this still doesn't work, I'll have to write that script.

Still the same

jdpc Too bad. There are still some options... Silly question, do you have audio passtrough enabled by any chance?

No, should I try it?

patrickkfkan jdpc I just tested a ton of new audio related updates from mainline. They work for me, but I never had much problems. Can you test this update (works with all H3 devices): libreelec-h3.arm-9.80-devel-20190916172159-d52e8dc.tar

Just tried it and it still has the same problems as before

shahidali55, roel and others with HDMI audio issues. Please test this universal H3 update file if it changes anything:

libreelec-h3.arm-9.80-devel-20190829200008-9d68e4b.tar

This is for any H3 board, just put it in /storage/.update and reboot.

If anyone wants to do a custom build, this update includes only one additional patch, which should improve situation for A64 and H6 too:

drm: dw-hdmi-i2s: enable audio clock in audio_startup - Patchwork

Tried it on my Orange Pi PC and unfortunately the problem still persists. Thank you anyway.

Hi, I'm still having problems with HDMI audio. I'll try to summarize the problem and attach some logs in case they're useful.

I have a Orange Pi PC and a Samsung TV from 2009. When running at 1080p 60 Hz, the audio only works for a fraction of a second and then stops working for some seconds repeatedly. When changing the refresh rate to 23.98 Hz it seems that the problem is gone in the UI sounds, but there are still some audio cuts for 2 or 3 seconds when playing videos, but less frequently than at 60 Hz. The problem still persists at 720p 60 Hz and 50 Hz. When using a much lower resolution the problem is gone.

I tried 2 different HDMI cables and other HDMI inputs in the TV to no avail. It doesn't seem to be a problem with the TV, because it works fine with the old OpenELEC builds with legacy kernel. Also, it works fine with two other monitors at 1080p 60 Hz.

Here are the logs:

Just an update on my HDMI sound problem with the Pine64+ board and my Samsung LE32B550 TV.

HDMI sound now is possible if I switch the display resolution in Kodi to 1920x1080i. However LibreELEC starts with resolution set to 1920x1080p by default which should be ok according to the provided EDID.

Could this be a problem with the clock driver or does my TV provide a malformed EDID?

I'm having the same problem with an Orange Pi PC and Samsung UE37C5100 TV from 2011. Sound works for less than a second, then silence for some seconds, then sound again, and so on. I also discovered that sound works fine when using 1080p but a refresh rate lower than 50 Hz, like 24 or 30. Sound worked fine in the old OpenElec versions based on legacy kernel.

jernej if you want some logs just ask and I will provide them. In any case thank you so much for everything you have done, everything else is working fine
