I’m pulling out my hair as I can’t figure it out, it somtimes stops working and I can’t figure out why
So most of the time my setup works and I have correct audio, also with DTS audio tracks. This morning all DTS tracks are not correctly downmixed. I’m not getting the center channel in the mix so missing all dialog.
TV is the LG 65c16 Supported HDMI Audio format (Depending on model):
True HD (48 kHz),
Dolby Digital / Dolby Digital Plus (32 kHz, 44.1 kHz, 48 kHz),
PCM (32 kHz, 44.1 kHz, 48 kHz, 96 kHz, 192 kHz)
Your log set has debug disabled. Attached you find instructions how to collect a log set, we want to see.
First of all your connected audio device claims to support MAT (metadata enhanced audio transport) which is typical used for TrueHD (and Atmos). Is there a reason why you don’t have TrueHD enabled?
To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem.
Depending on the used skin you have to set the settings-level to standard or higher, in summary:
enable debug logging at settings->system->logging
reboot the OSMC device twice(!)
reproduce the issue
upload the log set (all configs and logs!) either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
publish the provided URL from the log set upload, here
Thanks for your understanding. We hope that we can help you get up and running again shortly.

I just disabled everything except AC3 and AEC3

The TV is reporting support for only two PCM channels but you have your channels settings in Kodi set to 7.1 which is going to cause issues for anything that isn’t being output bitstream and has more than two channels. You should set your channels to 2.0. If there is a soundbar or something connected to the TV which dictates you wanting multichannel preserved for these formats then you can set the passthrough settings for both enabling AC3 and AC3 transcoding which will allow the multichannel to work through a TV with this limitation.
re-enabled TrueHD on the Vero V in the audio settings? The TV states it is compatible to MAT which is the transport mechanism for TrueHD and Atmos. Even if your TV is not able to decode TrueHD, it should be able to passthrough this signal using eARC. Only, if your connected soundbar does support neither TrueHD nor Atmos, you should disable TrueHD on the Vero V.
Other idea: Did you activate an optical connection between TV and your soundbar but used before the HDMI connection (eARC)? Such things would explain why now you only see 2 channel PCM support.
Have set to 2 channels and that works as expected.
I only have the Vero and the TV, there is nothing else connected nor was there ever.
I suspect that it is because I disabled the Fast Startup of the TV, since then I also have intermediate issues that CEC is not picked up and I need to turn the TV off and on again.
The LG 65C16 TV supports up to 8 channels (7.1) of uncompressed LPCM audio via an HDMI input when using eARC to an external audio system. However, when the TV’s internal speakers are used or the audio is passed through without eARC, it is typically limited to 2-channel stereo PCM.
