Im having a strange issue with PMS. I have a current Mac Mini (i5 8Gb RAM etc) latest version of Plex, Marantz 7001 Amp. I can get 5.1 signal if I use PHT but 5.1 has just stopped working through PMS using Safari. I have tested a number of files on both PHT & PMS all of which gave a 5.1 output previously.
As far as I know, no settings have changed. I have tried looking through all the settings and have systematically turned off a bunch of the direct options (which I had to play with the eliminate a jittering issue with the video signal) but there doesn't seem to be a setting option that addresses this new issue.
I can use PHT but prefer to use PMS
Any ideas?
