Silly problem with 2g speaker.

This is an issue with the speaker on a 2G

The phone rings, the calls work.
The alarm rings.
Pretty much everything works except that ipod wont play music on the speaker. Games wont play any sound thru the speaker.

Hooking up my ear phones is the only way to get music out.
Stuff I have tried.

a. Reset all settings.
b. Plug and un plug the ear phones a few times.
c. Hard reboot.

sounds as if the iphone believes that there's an accessory plugged in which is why the ringers work, but not the sound from the iPod app or any other games

try restoring the iPhone as see what happens
