I have a iPhone 4 and i am having an issue with my sound not working when i plug my phone into a universal dock from Apple. It affects the alarms, ringer, unlock noises and ringtone noises. So more or less everything. I am trying to figure out why. It is not the new year bug because it has been doing this for a few weeks now. Could it be the dock? I need some help with this issue because i use my iphone for all my alarms and it not going off is not good for my work and personnel life. Thanks in advance.
