Why doesn't dopod S 1 Elite Edition make any noise?

First, make sure mute is not turned on.

Play the music and try to see if the speakers are normal.

Secondly, see if you have installed this software, which has the option of related music formats.

After the connection, your ringtone and prompt will be muted, so you can have a look.

If not, back up the contact grid and try to eliminate the software problem.

Finally, it can only be a hardware problem. Send it for repair.
