Hi.

Went from Kodi 16.1 to 17.6 and got a sound issue. Probably a setting, but i have tried many without a solution. On 5.1 movies i have to set the sound 200ms ahead to be in sync, 2.0 sound works fine.

I have speakers set to 5.1.

I do not use passthrough but i have it hooked up ta a home theater with 5.1 speaker (Samsung HT-C6600, Built-in Decoders: DTS decoder, DTS-HD High Resolution, DTS-HD Master Audio, DTS-HD decoder, Dolby Digital, Dolby Digital Plus, Dolby Pro Logic II, Dolby TrueHD)

I have setup Kodi after https://kodi.wiki/view/Chromebox 3.4Recommended Settings, but som options are not available: 
Vertical blank sync: Let driver choose
Deinterlace video: Auto
Video scaling method: Lanczos3 - Optimised

And i am not sure what Audio output device i should use, ALSA: HDA Intel, GSM LG TV on HDMI #0 or some other like ALSA: HDA Intel, HDMI #1

Any clues? Do you need more info?

 firstly, I'd reset the audio offset to zero, then enable passthru (on ALSA: HDA Intel, GSM LG TV on HDMI #0, or whatever is connected to your HT).  If you have your Chromebox connected to the TV vs connected directly to the HT, then I would fix that first.  The speaker config should match your actual config, so 5.1 is correct.

and yeah, I need to update the recommended settings.  Maybe when v18 hits beta.  Right now, the default settings for 17.6 are perfect other than enabling passthru and setting your speaker config
