Why do headphones work, but not inline mic and controls?
Headphones work great, no issues. The in-line mic and volume/skip buttons do not respond at all. When a call comes in when I have headphones w/ mic in, it comes through the headphone but I must speak into the mic on the phone.
I understand there's a contact in the headphone jack that the phone registers when you plug a supported headset in...as far as I can tell, this is not obstructed by lint or anything.
I've tried several different pairs of headphones...the stock iPhone 4 don't work, I tried my friend's stock iPhone 4 headphones, and a 2 different 3rd party pairs...I've ruled out the headphones as the issue.
I replaced the Headphone Jack & Volume Control Cable. This was no easy task, so I was very happy to have everything turn back on and work perfectly, but terribly frustrated when the inline mic and controls still does not work.
What else can I possibly try?
Thanks in advance for any assistance.
