No audio out Ugoos AM6B+

Help & Support Hardware
1

Installed latest 19.3 CE on a new Ugoos AM6B plus and can’t any sound from the AV Out (jack plug to 3RCA). But it works fine with normal Android Kodi.
I’ve tried all the available audio out options in settings, turned on/off passthrough etc but I just get silence with any codex ?

You are sure you have switched to “analog audio” in kodi settings?
It looks like you have HDMI enabled in audio settings.

Here is log while switched to analog default PCM.

When I switch to analog audio the box slows (circle going around) and videos are jerky and then they just freeze after a few seconds.

The other analog audio option does the same.

Had to reboot kodi to get a log as it kept on failing.

No sound from tv or amp when switched to analog.

With android kodi I haven’t changed any settings and AV Out audio works with amp and of course the tv audio works as normal.

Thanks for your help.

ok, try this by SSH connection:

mount -o remount,rw /flash
fdtput -a g12b_AM6b_b4g /flash/dtb.img /auge_sound/aml-audio-card,dai-link@1/cpu system-clock-frequency -t i 11289600
sync
reboot

Then test again, also switch to analog audio. I am not sure but I think in CE you have not HDMI & analog the same time.

Thank you, I will give that ago, but it might take a while as I’m useless with computers and haven’t done SSH before :slight_smile:

Then please use this dtb and replace your dtb.img on COREELEC partition with it:

Do not forget to rename it to dtb.img!
