Going to follow the posting guidelines here and just fill in the template. :)

 

  • Your ATV model (2 or 3) and firmware version (found under the ATV settings > general > about > Apple TV software):
    • Apple TV model 3, Firmware 5.3 (6105)
  • The DNS server set on the ATV (found under the ATV settings > general > network > DNS):
    • DNS server is 192.168.1.8 (my PlexConnect IP)
  • The local IP address of the device that PlexConnect is installed on:
    • 192.168.1.8 (PlexConnect is bound to that IP)
  • The device and operating system (including version number) that PlexConnect is installed on:
    • PlexConnect is installed on my Plex server, a generic PC (quad core, 8GB RAM) running Ubuntu 12.04.5.
  • The device and operating system (including version number) that the Plex media server (PMS) is installed on:
    • PMS is installed on the same machine as PlexConnect, a generic PC running Ubuntu 12.04.5.
  • The Plex media server (PMS) version number you are running (do not put 'latest'):
    • PMS version 0.9.11.7.803-87d0708
  • The local IP address of the device that the Plex media server (PMS) is installed on:
    • PMS is installed on 192.168.1.10 (same machine as PlexConnect, just a different IP)
  • The PlexConnect version number. If using Github source then a time and date of download (look at the creation date of the folder) and if you are using any non-standard setup e.g. Plexify or a fork.
    • PlexConnect updated on Feb 11, 2014.
  • The contents of your 'Settings.cfg' file (this is created at first clean shutdown of PlexConnect, using CTR+c)
    • [PlexConnect]
      enable_plexgdm = True
      ip_pms = 192.168.1.10
      port_pms = 32400
      enable_dnsserver = True
      port_dnsserver = 53
      ip_dnsmaster = 192.168.1.1
      prevent_atv_update = True
      enable_plexconnect_autodetect = False
      ip_plexconnect = 192.168.1.8
      hosttointercept = trailers.apple.com
      port_webserver = 80
      enable_webserver_ssl = True
      port_ssl = 443
      certfile = /usr/local/bin/PlexConnect/trailers.pem
      allow_gzip_atv = False
      allow_gzip_pmslocal = False
      allow_gzip_pmsremote = True
      loglevel = Normal
      logpath = ./log
      ip_webserver = 192.168.1.8
  • Detail on the media file if it is an issue related to playing a media file
  • A detailed description of the issue (the clearer you can make this the better):
    • While playing back a video with DCA audio (see pastebin above) the audio starts to noticeably drift out of sync with the video. Inside of  20 minutes of playback, the audio is behind the video by about 4 seconds. Movies with DCA audio do NOT do this with my Android Tablet, or with Plex Home Theater on a PC or Mac.
    • Movies with AC3 or other audio do not have this issue on my AppleTV - they play just fine.
    • I have three AppleTVs in the house - two ATV3s, one ATV2, and all exhibit this issue.
    • Pausing the video, going back out (one click of the menu button) to the video description screen, then hitting play and 'resume video' allows the stream to start again with sync reestablished, but it gradually drifts again.
  • Ensure you post your 'PlexConnect.log' file to pastebin and post the link ('PlexConnect.log' is located in your PlexConnect folder). If possible, follow these steps to create a "more detailed fresh" one:
    • http://pastebin.com/um286PMm
    • Had to cut off part of the beginning of the log, as pastebin wouldn't allow me to paste it (it exceeded the 512kb limit). I captured the selection of the video and start of playback.

I've tried everything I can think of, short of re-encoding the audio in each one of my files. Any help that you can provide is appreciated. Thanks!
