Looks like I found a solution for this: I used MPlayer with the parameter "-af volume=1" and was able to decrease/increase the sound without any distortion.  I also lowered the global sound levels with alsamixer because MPlayer always seems to start with the volume at 100%.

I have a Gumstix Overo Earth and a Palo35 Expansion Board.  When I plug my earphones into the audio out jack, I am able to hear audio just fine by using MPlayer, but whenever I try to raise or lower the volume via MPlayer, the sound gets horribly distorted.  So I am unable to adjust the volume without the sound being affected.

Has anyone else had this problem?
