jhs39 13 Posted September 20, 2014 Share Posted September 20, 2014 I am having a problem where the soundtrack for some movies is muffled when played with Media Browser. Generally dialogue is very low in the sound mix and hard to understand. These files play fine with Play On and also with VLC and Potplayer. The only place they don't play right is Media Browser. Do soundtracks need to be a specific format for Media Browser to play them correctly? Link to comment Share on other sites More sharing options...
Happy2Play 8140 Posted September 20, 2014 Share Posted September 20, 2014 Do you know if they are being transcoded? Link to comment Share on other sites More sharing options...

Happy2Play 8140 Posted September 20, 2014 Share Posted September 20, 2014 Arrow down while playing something or look in the logs. Link to comment Share on other sites More sharing options...
jhs39 13 Posted September 20, 2014 Author Share Posted September 20, 2014 When I arrow down it says direct play. I don't see any mention of transcoding in the log. Link to comment Share on other sites More sharing options...
speechles 1912 Posted September 20, 2014 Share Posted September 20, 2014 What codec is being used? If it isn't aac the roku will merely pass-through such as DTS or ac3. Sent from my Nexus 7 using Tapatalk Link to comment Share on other sites More sharing options...
jhs39 13 Posted September 20, 2014 Author Share Posted September 20, 2014 AC-3. If Media Browser is merely playing the soundtrack as pass-through why does every file I come across with this issue play fine in Play On? Why is the sound perfect when I play on my computer using a media player like VLC or Pot Player? If the file plays fine everywhere but Media Browser it seems unlikely that the problem is with the file. Link to comment Share on other sites More sharing options...
speechles 1912 Posted September 20, 2014 Share Posted September 20, 2014 Is your roku set to 5.1 surround or stereo? How many channels is the ac3? 2.0, 5.1, 6.1?? In pass-through this matters for sound db level, aka, volume. Sent from my Nexus 7 using Tapatalk Link to comment Share on other sites More sharing options...
jhs39 13 Posted September 20, 2014 Author Share Posted September 20, 2014 (edited) My Roku is set for surround sound. The video file has 2 channel AC-3. I switched the Roku to stereo and the dialogue is audible now but the soundtrack still doesn't sound right to me--it sounds like I'm listening to the movie through bad TV speakers rather than a surround sound system. The same file plays fine through Play On with my Roku set to surround sound and it sounds much, much better.

speechles 1912 Posted September 20, 2014 Share Posted September 20, 2014 Is play-on upscaling the 2.0 to 5.1 transcoding the ac3 to aac? Sent from my Nexus 7 using Tapatalk Link to comment Share on other sites More sharing options...
jhs39 13 Posted September 20, 2014 Author Share Posted September 20, 2014 My receiver shows that the sound is 2 channel LPCM when played with Play On. Link to comment Share on other sites More sharing options...
