I have a problem with my matroska file, converted from an avi file. The sound in the avi file is fine, however there is no sound in matroska. It was working previously on another file, but I do not know having anything changed. I have tried to play it with different players, all play the video fine, but no audio at all.
When I look at the streaming info in xine, it reads:
Audio:
has: yes
handled: yes
ignore: no
codec: unavailable
fourcc: 0x0
channel: 0
bitrate: 0
bits: 0
samplerate: 0

vlc streaming info reads:
codec: mpga
language: francais
type: audio
channels: 2
sample rate: 44100 Hz

mplayer says:
[mkv] Track ID 1: video (V_MS/VFW/FOURCC), -vid 0
[mkv] Track ID 2: audio (A_MPEG/L3), -aid 0, -alang fre
[mkv] Track ID 3: audio (A_MPEG/L3), -aid 1, -alang ger
[mkv] Will play video track 1
[mkv] Will play audio track 2

Any help is appreciated!!

Hi again,
I tried to extract the audio from the matroska file-it is empty! I used mmg to convert the avi to mkv, and
mkvextract tracks test.mkv 2:french
to extract the mp3 file-it has 0 MB! I tried to extract it directly from the avi using:
mkvextract tracks test.avi 2:french.mp3
here the answer:
(mkvextract) No segment/level 0 element found.
progress: 100%
any idea? It worked the other day so there seems to be a problem. But not even re-installation fixes the problem
Cheers,

ahab

I'm having the same problem with an mkv file. Any ideas? Used VLC, totem (with added codecs), Mplayer.
