The problem is that Kodi has never supported this scenario. It is not trivial to output audio to two different devices and maintaining a/v sync. The cheapest and dirtiest way to implement it would be to level audio sync to the average delay of both devices by returning the delay of one device for one call and the other for the next call. If pulse did it that way it would explain the alternating skips and duplicates of audio packets indicated in the log.

Let's find it out. Set the output to combined and choose "Fixed" and samplerate 48000 and 2.0 channels. What happens now?

What does this test tell us? How is samplerate related?

Here is what I think:
pulseaudio has fallback samplerate of 48 khz, which works on a analog device and also on every hdmi output device. The 44.1 khz that was probably used in his testing was only supported by the analog part, so additional resampling to the hdmi out would have happened. So let's try if PA behaves better if both output devices get a chance to use the same samplerate.

on almost all video/mkv files. i'm using pulseaudio with "combined sink" for ages, always worked like a charm..
does 16 alpha fix this one as well? seems similar to this thread

So: No issue with this sample, right?

Does this only happen when you play 25 or 50 fps content at 59.94 hz?

Or in other words - do you have a sample which is not 25 fps (50i) that produces this issue?

I am aware of it. See the other thread in Linux forum, please. Give me until next week, on holidays currently.
