No sound when playing .RM video files

[barney_1]

Hi Folks,

I've been trying for a couple weeks to get this problem fixed but no dice. So, here it goes:

Kubuntu 7.04 Feisty (development)
Kaffeine media player 0.8.3

I can play .RM (realvideo) files and see video perfectly but I have no sound. I have tried installing the w32codecs, the xine-extracodecs, and several others.

When I run kaffeine with this command:

kaffeine --verbose

I get this error when trying to play a .RM file:

xine: found demuxer plugin: RealMedia file demux plugin

Any thoughts on how to correct this?

Try to use VLC.
This program has every codec you can imagine and it can play just anything.

I'm having this problem, too. It started happening in Feisty; in Edgy, Real files played audio just fine in Kaffeine as well. It was exactly like one problem I had a year ago when I couldn't get WMVs to play sound despite having w32codecs installed; it turns out I had to tweak ~/.xine/catalog.cache to get it to play sound. Maybe playing with that file again will get it working, but I'm not so sure.

chggr: I'd prefer not to use VLC for a number of reasons, one of which there are some format it actually doesn't support (I have a few videos encoded in Indeo v4, which it doesn't support). So fixing xine to get this working would be preferable.

ETA: Found a solution. Open up ~/.xine/catalog.cache in a text editor and find this section:

[/usr/lib/xine/plugins/1.1.4/xineplug_decode_real_audio.so]
size=11300
mtime=1171041406
type=131
api=15
id=realadec
version=10104
supported_types=52494336 52559872 52756480 
decoder_priority=5

Bump up the 'decoder_priority' value to 10. That should get audio with Real files working.

First scratchy sound in SDL games, now this. And Canonical smoothed out all my audio problems with Edgy...

Hey, great tip, Thanks! I'm not on my Feisty box right now but can't wait to try it out.

As for the support not being there for Feisty, I would imagine that as it hits RC in April these things will get ironed out. Hopefully this info can be useful for the developers.

Hi. I installed Feisty Herd 5 yesterday and was really bugged about this...

Thanks. This solution works. Has anyone opened a bug in Launchpad? We don't want this to creep into the final release...

Sorry folks, forgot to report back that this fixed my sound problems as well.

Say, I've never files a bug report. Is there a how-to about it somewhere around here? (I probably should have searched for one before asking, but oh well)

Thanks man! The solution works like a charm!

This fixed gxine as well in xubuntu after a dist-upgrade.
