Bug#498995: vlc: no sound (mute) with a52 audio codec within mkv file

Fab F fabuzz at gmail.com
Mon Sep 15 09:11:38 UTC 2008


Package: vlc
Version: 0.8.6.h-1
Severity: normal

I have no sound with one of the video I try to watch (works within totem)

When I start playback with vlc in command line :
[00000339] a52 decoder: A/52 channels:6 samplerate:48000 bitrate:640000

Selecting "none" in the Audio Track menu, then selecting back the right 
track doesn't help.

When I enable verbose (-vvv) :
