The “channels” setting is how many PCM channels Kodi sends out. The EDID information in your logs shows support for only two PCM channels. I’m not sure if this is a limitation of your TV or the soundbar and how you have it connected. If it is a limitation of the TV and your Vero is connected to your TV then setting it above two channels will be problematic for source material that contains multichannel soundtracks. If the Vero is connected directly to the soundbar and this soundbar supports multichannel PCM then you should be able to set the number of channels to what the soundbar supports without using passthrough and/or transcoding. There is a very informative guide to audio configuration that can be found here…
