Why does my clip zip play quieter than others (AUX PORT)?

Is the player’s volume setting (not the volume rocker), under the player’s Settings, set to high? Note that if you don’t have such an option under Settings (the EU has “outlawed” such a setting), choose the Reset factory defaults under System settings and then, when prompted for the region, choose N. America or Rest of world–do not chose Europe, which will limit the volume setting, as noted above.
