Like any media player HDMI connected to a TV - if you do not change any settings at all in Kodi Audio - All Audio formats will be downmixed to regular 2.0 PCM audio and output thru TV speakers, regardless of the quality of Firmware used.

Unless your TV supports DD, DD+ and DTS, you will not get any Passthrough Audio at all, when selecting those options.

This is a Krypton Passthrough Audio thread, mostly concerning HDMI connected AVR's.
You need IEC Firmware support for any DTS and HD Audio passthrough when using Kodi Krypton..

Thanks for quick response.

I suspect a number of Kodi users do not have an AVR.

My understanding of your reply is that the Amlogic API issue would be irrelevant when connecting my box via HDMI to my TV (with no DD, DD+ and DTS) and using my TV speakers and that I should leave the kodi audio options set to default.

If my understanding is incorrect please let me know.
