audio sync with kodi 17.1

since upgrading to kodi 17.1 I am having terrible audio sync issues with live TV.
I’m running 17.1 on a 1st gen Fire TV.
TVHeadend is 4.0.9 & the kodi addon is v3.4.19
Recordings play back fine. The problem is only with live TV.

This same setup plays fine when I use MRMC and I believe all of the PVR & addon settings are the same.

I’ve attached a log file. I hope someone will see a problem that can be resolved.
