movies are played too fast

Strange thing…

After retourning home from holiday, my Plex Home Theatre (on a mac mini 2011, Plex Server on a Synology DS 213+) plays all movies too fast (app. twice the normal speed). Hence I have no sound.

Strange thing is that I haven’t made any changes to my system while I was away…

I tried another mac (iMac 2011) and everything works fine, so I don’t think that it’s a problem of the NAS.

Do you have any ideas / solutions for this?
Thanks in advance

Here’s the logfile.

Does this happen only on movies with DTS audio or on all movies? Can you try on 10 movies with different audio codecs to be sure?

Sorry for ma late response. But it happened with all movies. But meanwhile the problems is gone.
