Ever since I got my Asus eee PC 1000HE installed with eeebuntu linux I have had problems with very low volume on the speaker, even tho the speaker volume slider was showing max volume. I didn’t spend much time investigating why this was, just accepting it. But today I found the solution to it, and it was very easy. Just right-click the speaker icon, select preferences. A new windows pops up, if you select the “LineOut” device by clicking it, and then click the speaker icon again to adjust the volume slider you will notice it’s only at 50%. Just set this up to 100% and you will have all the volume you need.
