Audio/Mic Problems

Lately I have been having mic/audio problems with I am t-pain. It gives me a really loud buzzing sound, then isn't letting me record right. It sounds like a buzzing echo sound. With both my voice and the music. I have tried to reinstall. Any ideas?

It actually gets worse buzzing sound when I turn the volume up too... any ideas?

I have tried to turn off wifi and location too. It does not work neither.

hello there,
I am having the same issue w/ my app and i am using the iphone 4. i got a response saying it was due 2 the iOS firmware upgrade. wen i sing in2 the app it sound distorted and lowering the volume wont help. we need 2 wait till smule has a update on the app 2 fix this app.
