MP3 Plays Only In Command Line
Hi I am still battling with sound on my ThinkPad 600 running Xubuntu. I have managed to get some sound and even play MP3 via command line - mpg123 and mplayer. But I cannot get any program to play it. It either doesnt play at all or plays so crackly you cant even hear the music. Is this a hardware limitation or am I doing something wrong? Please help, I am a fairly new Linux user. When using mplayer via command line I noticed that it said 'pulse' is this the audio output engine/settings it is using as under Mixer there is also a mention of Pulse under one of the Output options - along sine OSS and Alsa. Your help would be greatly appreciated.

You can use VLC via the command line, right now the exact commands escape me :S Maybe the answer will be on http://wiki.videolan.org/VLC_command-line_help -- Regards, James. http://www.jamesbensley.co.cc/
James I am looking for a way of playing them without using command line, if possible.

Pulse refers to PulseAudio which enables sound from local and remote applications to be mixed together and then output (ALSA dmix can do the local mixing bit). My suspicion is that with the GUI applications there is more happening and somethimes the MP3 decoder thread doesn't get the CPU often enough to be able to keep up with the output. Sometimes this can be fixed by: 1. Giving a higher (sometimes even real time) priority to the decoder thread. 2. Having a little more buffering between the decoder and the output - this means there is more time between when the decoder can run (because there is space in the output buffer) and when it must run (because the output buffer is getting empty). How to configure anything like that would depend on what GUI applications you are using and what media framework they use (e.g gstreamer, xine, vlc). HTH, Steve.

The problem could be because your installation is using PulseAudio as the audio layer/mixer. I had a very similar problem on a Mandriva box a few years ago - it was a dual-core 2GHz Athlon, so wasn't exactly puny (at the time), but would play MP3s in short staccato chunks. A look at "top" showed that PulseAudio was sucking 100% of one of the cores just doing that simple task (and, IIRC, mpg123 states it can run happily on a 300MHz P5, or something of that ilk). I rummaged around and changed the audio layer to use ALSA and it's been perfectly fine since. Have a Google around for "disabling pulseaudio linux" for a few clues as to how this might be done, but I've not tried it on *buntu, so can't comment on exactly how...
