Video playback speed issue when enabling DTS.

Dev Community Apps & Creations

I'm using the latest Plex Home Theater binary package on ubuntu 13.04 and

I'm having issues with video playback speed when I enable DTS reciever under

preferences. As soon as I enable DTS videos start looking like they're in fast forward mode.

Is this a known issue?

 

Don't know if this issue is isolated to the latest binary release as I'm rather new to using PHT under linux.

 

Thanks!

I think this is what you're looking for, and believe it or not, it is related to the audio driver. Since you're a plexpass member, you should be able to find it here, starting with Tobias' post:

I came here after a search for the same issue. I’m not on Linux however, instead I’m on OS X. Here I have the same issue that DTS causes the playback speed to increase to about 120%, just enough to make voices high pitched. Disableing DTS / switching to Analog solves the issue with the playback speed but obviously decreases the sound quality. I’m not familliar with Linux so I don’t know if the solution provided in the linked thread somehow applies to OS X too…

I am having the problem on any video with Dolby 5.1. non-dolby 5.1 playback is ok. A The link that MattyK provided is not working, unfortunately.

I messed around with my audio drivers (ubuntu 13.10) because i couldnt get 5.1 playback through my optical-out. (or at least the ubuntu sound utility didnt recognize it as 5.1, only 2 channel). I fixed the drivers by removing and reinstalling pulseaudio. 

Any suggestions or at least a fixed link in MattyK's post?

Thanks!

I'm also having the same issue, playback seems as if it is on 120x or more playback speed.

this only is happening to Plex as all my other video apps including Kodi work just ine.

I have a quad core intel with a nvidia gpu /w hdmi out which is running the video/audio to a 1080p TV and yamaha receiver.

I can't see how this is in anyway related to hardware/software that is not a part of plex  since I have already stated, everything else runs just fine outside of plex including Kodi.

any help would be appeciated.

I have the same problem. This was working when I had the server formatted as window 7. I recently converted it to Ubuntu 15.04 and all of a sudden dts just doesn’t work. The reciever is a denon avr-4310ci.

Oh I did finally get this working, and here what I did to get it working but oh boy was it painful for Ubuntu 15.04

Remove Pulse audio: sudo apt-get purge pulseaudio

Confirm It really removed itself and move it if it hasn’t : ls -l /usr/bin/pulseaudio
sudo mv /usr/bin/pulseaudio /usr/bin/pulseaudio.bad

Install a real Audio program: sudo apt-get install gnome-alsamixer

Confirm your channels are not mutted.

Go to Ubuntu Home and search for Sound. It should come back with gnome also mixer
Unmute any channels if they are mutted

Here’s an example of How mine looks

Fire up Plex Home Theater, goto Preferences > Audio ouput and select your settings

for me I only had to check DTS capable receiver and TrueHD capable receiver

Everything works fine with DTS from there.
