I had similar problems with low volume until someone suggested using
alsamixer.  Its a character-based gui app that lets you set loads of
settings for capture and playback.  Making some adjustment via alsamixer
made my problems go away.

If  you are not using alsa, I recommend that you switch and then use this.
