Does SL-5500 use ALSA sound layer for sound? VLC 0.5.3 uses OSS sound 
layer and is not capable of ALSA yet.

The way solve it for you is installing the alsa oss emulation and 
configuring it in the right way.

That is fine. I should not have left this message in there it is way to 
verbose.

I made some comments in the vlc log. You miss the library librt, go and 
get it from the zaurus download page.

Install librt from the package on 
www.videolan.org/vlc/download-zaurus.html it is needed by vlc !

This is no problem it only means you have not user preferences.

hmm ... can't it read from the audio device ??

I miss a message saying
	"main module debug: using audio output module "oss""

instead it defaults now to the "dummy" audio output module.

So VLC could not open the sound device and everything that happens 
hereafter has no effect for the audio.

hmmm, audio is too late now .. vlc tries to downsample the buffer it has.
