I aways tried to avoid using esd or arts sound mixing, because they turned out to be slow for me comparing to the mixing through alsa dmix plugin. It was nice to see that I dont have to edit ~/.asoundrc manually in recent FC because alsa mixing works well by default. Now to your problem, check out the following: I assume you are using speakers with external amplifier. Check how the sound quality (music or something) depends on the Master level in you audio control panel (you can run alsamixer to check that). If the output level of your soundcard is so high that the signal goes out of linear range of preamplifier the resulting sound will be distorted. If you find that this is the case - set you Master and PCM to maximum level when there is no distortion and use hardware volume control from now on.
