I run Plex on my DS1019+ and when I connect to http://192.168.0.182:32400/web/index.html and click on a certain video, it will ply the video but no sound.
If I open the video with VLC it plays the video and sound, but the video is 90 Degs turned, but in Windows media it plays the video correctly with sound.
The video details are
Version 1.28.0.5999
Movie is
VIDEO 1080p (H.264)
AUDIO English (AC3 5.1)
Here are a couple logs but not sure which logs are required.
Thanks
