On Ubuntu 12.04 why does TeamSpeak has everything is muted?

Hi TechyV buddies!
Can you help me configure the problem that I encounter in using Ubuntu 12.04?
When Ubuntu 12.04 was release, TeamSpeak disabled me from talking or hearing sounds.
I am not certain what have caused this kind of problem.
It tells something about my speakers and my Microphone being muted/disabled.
What about Pulse Audio?
Does it have anything do with the problem?
I am a bit new to Linux so I am still trying to know a lot of things on it.
So if there is anyone out there who knows something about my problem kindly help me please.
I would be very thankful of any help to this matter.
Thank you!
