AAC LATM 5.1 now plays as white noise using V1.7.2.3878 beta of PMS

Hi, I am in the UK and currently using the latest PMS V1.7.2.3878 beta. I’m getting a white noise sound on DVR recordings with 5.1 LATM sound. 2.0 LATM is fine. This did not happen when the recordings were in native TS format. Neither when the remux setting was actually switched on in testing on older betas. The error from the PMP log is:
[ ERROR ] PlayerComponent.cpp @ 511 - ffmpeg/audio: pcm_s32le: Invalid PCM packet, data has size 3 but at least a size of 24 was expected
2017-06-03 10:37:45 [ ERROR ] PlayerComponent.cpp @ 511 - ad: Error decoding audio.

Hardware: Late 2012 Mac mini and HDhomerun
