no sound from speaker, headphone with karaoke effect
just got my ipad2 for a week and need some help.
now when i turn on my ipad2 and play music or youtube clips, the sound comes from speaker for only about 5-20 seconds, and all of sudden it's gone. and when i use the side volume buttons it will tell me that it's adjsuting the volume of headphone, even though there's no headphone plugged in. so now if i do plug in a headphone, i can hear the music, but with karaoke sound effect (vocal track is digitally erased, with background music unchanged).
I realized that I had installed an app called "pocketsing", a free karaoke effect app. But i had deleted it. and after having this sound problem, i have tried reboot (holding home and power), erase all settings from ipad, restoring from itunes...
nothing worked. is it possible that this "pocketsing" app actually corrupted the ipad2 firmware somehow? can't imagine why even after restoring in itunes it still won't work.
any ideas or suggestions? thank you!
