Nothing. Use headphones if desktop speakers are inconvenient.

You can try adjusting the mixer and player settings for best sound, but notebook speakers are notorious for crappy audio. A good quality set of headphones are well worth the money.

I've found that if you run 'alsaconf' then 'alsactl store', it will set you speaker volumes and PCM to the right settings and save them. On my laptop setting the PCM is VERY important. If you set it to the wrong value the sound will be really messed up.

Well, here's the wiki on it:
http://en.wikipedia.org/wiki/PCM
if you run alsamixer, you'll see a PCM option, this should not always be at 100. On my laptop things start to sound weird if I put it at 100, instead I run alsaconf and it sets it to around 80 or so, I guess you could mess with it until you get the right settings.

EDIT: it seems I am a bit slow, I forgot to refresh the page in a while
