I am experiencing a problem where whenever I watch a live stream (NHL games via the NHL.TV addon) the stream is out of sync (by about a second). I can manually correct this by either either forcing the stream to buffer (trying to skip ahead in the stream, which causes it to buffer and come back in sync) or manually offsetting the audio via the OSD. Either correction is temporary however, since gradually the stream will fall back out of sync (usually takes 5 or 10 minutes).
For some background on my setup, I used to use this addon with both an ODroid C2 & Shield TV directly connected to my TV via HDMI, and I did not have these problems. However, this summer, I upgraded my setup and added in a 7.1 AVR (only set up in 5.1 for now) into the mix, which I believe is causing the problems. I have used the C2 with the AVR, as well as a MINIX U9-H (LE dual boot, now LE flashed to internal storage), and both have the same problems with audio sync of live streams.
I can watch any other content on these boxes through the AVR (localy streamed videos from my server, as well as internet streams of youtube videos and NHL game replays) and I have absolutely zero sync issues.
Here is a debug log showing me playing 2 livestream games (the first stream died on my almost as soon as I started it, so I selected another stream, and the audio was off), as well as 1 archived game. The livestreamed games had the audio off by about a second, while the archived game's audio was in sync.

I had originally posted this on the kodi forums, but didn't get much traction, so I figured I'd try on here as well. I'll try to grab an updated debug log from the U9-H tomorrow night when there is another game on.
If there is any other information I can provide, please let me know. Thanks
