Custom EQ Distortion Problem!

I have have the Sansa CLIP+ for a couple of months now and I have had a couple of problems noithing I couldn’t fix my self but now I came across one that I Can correct. When I go to change the EQ to any of the presets or my custom setting all I get is distortion, I have tried formatting the player and resetting to factory level but this hasn’t work I recently updated the firmware to 1.02.15 and the problem came across a day after.

Can anyone help?

Thank you in advance.
