I’m using the Odroid N2 with 9.2.1 on an LG Oled C8 and there’s no dialogue channels on most of my videos. They play just fine on VLC on the same monitor so this is something with Odroid/Coreelec passthrough.
The reason I know it’s a passthrough issue is because if I change my audio settings in Kodi to 2.0, I get dialogue; if I change to 5.1, I get no center channel. These settings of course are irrelevant if Kodi is using passthrough meaning Kodi isn’t using it even though it should be so this is some kind of bug. I’ve attached a log and screenshots. Thanks. Oh, and I’m not syncing playback to display nor do I have EAC3 transcoding enabled.
The non-passthrough audio device is ALSA:aml-augesound, HDMI Multi Ch PCM. The passthrough device is: ALSA: AML-augesound, HDMI
The problem is on certain 5.1 videos, it’s simply not passing the audio through though Coreelec THINKS it is. I think these pictures will show you what I mean:
NOT passing through even though my LG supports it and no dialogue channel:
