Sound Issue w/HDMI and Latest Coreelec - Odroid N2


i’m having sound issues for some months. I did a fresh install on my Odroid N2 (up to date 19.X corelec), same issue. I guess that’s what you call dropouts or sound skipping : for one second, there’s no sound and my AVR loses information.

I’m using HDMI 7.1. I use a lot PCM multichannel because my AVR (Denon 4306) is too old to passthrough newer formats. It used to work like a charm.

I don’t have issues with all sound format.As far as i know i have issues with some E-AC3 like this one. It might have something to do with bitrate or atmos but i’m not sure.

I’ve just tried something important that confirms that at some point it was working like a charm : i have an old Coreelec18 on another card and i DON’T HAVE THE ISSUE with this one !

Any idea ? is this a known issue ?

On Kodi forums, people are complaining about similar issues…I’m surprised no one here noticed anything…It might be related to KODI19.
