Also HD audio is working fine on TV and passthrough with Kodi on it.

I guess frame rate switching only works in Kodi - not Neflix, Prime etc. - as I don't think they've rewritten their Android TV apps to do it?

On my Sony Android TV the only apps that work correctly with 50Hz content are the HbbTV ones.

I don’t use Netflix, Prime etc. only Kodi and that is working fine on the Sony TV.
Ah - I wonder which model range introduced frame rate switching to the Sony Android TV implementation - be useful to know.

(I know a lot of people who use MotionFlow won't see the issue - but once you disable it, it's really clear to see which sets do and don't support it, particularly if you are sensitive to 3:2, or are watching 50Hz Live TV at 60Hz)

Do you actually see different refresh rates enumerated in the Kodi settings menu?  Under Settings->System->Display, are you able to select different resolutions and refresh rates or is it locked to Android default video mode?  If only 60Hz mode shows up as available, then it's unlikely you're getting refresh rate switching.

I still have Kodi 18.9 on my Sony 55A89 and is working great.
Are there any here who already have Kodi 19 installed on their Sony A8 TV?

Hello all,
I have a Sony KD65 A89 and I'm running Kodi 19.0 on it.
Contrary to what other have said, audio passthrough to my Samsung soundbar is working fine for me, with all the audio formats I tried, although I didn't have tried any lossless audio passthrough. It sounds strange to me that, although having eARC support, I couldn't passthrough lossless audio though...
Auto frame rate switching unfortunately does not work on this TV and this is really a pity.
Switching from Kodi 18.9 to 19.0 I didn't notice huge annoyances, apart from an old anime in h264 format that started to give me seek problems when fast forwarding at more than 4x: with Kodi 18.9 it worked fine, with 19.0 seek is broken at >4x speeds or when jumping forward/backward. By now, it happens only on that single video series, I don't know what is wrong with that.

Another AVI using XviD codec plays really bad and makes audio go out-of-sync: the video stutters a lot. I can fix the video stuttering by disabling hardware acceleration in Kodi, but in this case video quality (for any contents I try) is much much worse. The same video plays fine in VLC, with no stuttering at all and decent video quality. This applied to both 18.9 and 19.0.

But the main problem I have is related to buffering and I don't think it's Kodi 19.0 specific, I'm pretty sure it was the same on 18.9, but I didn't use Kodi so much to state for sure. I think I'll open a dedicated thread to try to diagnose this. This TV has just a 100 Mbit/s ethernet card, but it must not be a bandwidth problem at all, but rather a Kodi-specific problem, because the same contents with VLC plays just fine. I will provide more details on the dedicated thread.

After all, using Kodi as an internal app for this TV is not a great experience: the interface is fast and snappy, but the mentioned issues hurt a lot. In general, I would say that Kodi works much better on a €20 FireTV Stick, although the UI is a lot slower on that device.

I disagree, Kodi on the Sony A89 is a great experience, it's fast and hassle free here and really works a lot better than on a FireTV stick.
I have connected the TV with an ethernet cable and the 100Mbit is fast enough.
Stuttering with certain files I had with Kodi on the FireTV stick and another box also bothered, so it is not the TV.
We think it is a great experience to watch a film or series with the Sony A89.

Glad to know it works well for you, fact is that all the problems I mentioned don't exist when playing the same contents with Kodi from the same source on the FireTV Stick (even though using a WiFi connection, while the Sony TV is using a cable connection...). Also, frame rate change works on the FireTV Stick while it does not work on this Sony TV, and this is an objective actual limit. As a final note, the same contents with VLC on the same Sony TV play perfectly fine, while they does not in Kodi.
The only things where the A89 works objectively better than the FireTV Stick for me with Kodi is in UI responsiveness, startup time and library refresh time.

Maybe I'm just unlucky...

Does this Sony TV finally have frame rate switching in Android TV?  The big limitation of Sony Android TV apps has been that they all run at a fixed 59.94 or 60Hz refresh rate - meaning 25/50Hz content is a juddery mess.  Does Kodi now let you whitelist resolutions and frame rates correctly on this model - rather than just offering a fixed, single, refresh rate?

No, as I said frame rate switching does not work for me, although the option is checked in Kodi settings. I verified it showing debug info during playback: a 25 fps video is played with the output being at 60 Hz.

I must add that the result is not a "juddery mess", because the TV does a great job and motion is smooth (I am very sensible to this aspect - please note I use the Motion Flow feature), but a working frame rate switching would certainly be better.

No idea, but everything here plays well on the TV, also with Kodi.

Ah - MotionFlow hides a multitude of sins, and adds a huge number of its own artefacts.

I disable all motion interpolation on my home TVs - after all, you don't see it as a feature on monitors in control rooms - where I spend my daytime hours, and where I'm required to notice motion artefacts as part of my job. I want my TV to be as close to a control room display as possible.  

If you're happy with Kodi and MotionFlow - that's great for you.  There are quite a few of us who find the MotionFlow algorithm's motion interpolation artefacts distracting - so we disable it. I've seen it fall apart too often to leave it on for more than the few minutes I look at itwhen I get a new TV to see if it's improved much.  It's particularly bad on stuff with compression artefacts - as they confuse it more.

Just a clarification: I didn't mean to say that Motion Flow is REQUIRED for proper Kodi playback without frame rate switching. After all, motion compensation and frame rate conversions are two different things, I just wanted to say that motion seems to be smooth for me even without frame rate switching, perhaps also due to my use of Motion Flow. Please let's leave the usual flame war regarding frame interpolation yes/no out of scope.
