View Full Version : [all variants] Choppy video playback with ac3 in VLC

August 23rd, 2008, 02:48 PM
I have problems with slightly choppy video playback with video files that have ac3 audio (including DVD's), that is, there's a slight pause in playback every 20 seconds or so. I have tested video files with e.g. mp3 audio, and there is no such problems with those files.

My audio setup is as follows:
Sound card => M-audio Revolution 5.1
Output => Digital Coaxial S/PDIF connected to this amplifier (http://www.xtz.se/produkt.php?allmant=true&produkt=5&eng=true)

This is my VLC configuration file (http://folk.uio.no/michaeka/tilverden/vlcrc), and my .asoundrc file looks like this:

pcm.!default {
type plug
slave.pcm "iec958:CARD=Revolution51,DEV=0" # taken from aplay -L

Does anyone have any inputs on how it may be fixed? In mplayer I cannot play files with ac3 audio at all, but I have described that problem in a separate thread (http://ubuntuforums.org/showthread.php?p=5648489).
