Galaxy S will no longer play songs through ear buds. With ear buds plugged in, will only play using the built in speaker. Have tried two different sets of buds, both worked on Nano fine. I looked in the Settings section and the only things in the Sound section were putting the phone into silent mode or selecting ringtones and the like. I've shut off the phone, removed and replaced the battery all without effect. I have not added any software since I last used the earbuds to listen to music. The plug in the phone is clear of debris and the earbud plug appears to be fully seated when pushed in. Ideas anyone?
