Crashing on DS218+, only plex crashes (synology doesn't crash, just plex)

Last night, I got word from one user who had problems with DTS-HD 7.1 audio.

He observed PMS would fail any time DTS-HD 7.1 audio was encountered by PMS 1.29.1.

We updated to the forum preview of PMS 1.29.2

Since that update, his DTS-HD 7.1 does not fail.

Might your PMS be failing in this manner?
