Cant join voice chat/mic muted bug

Okay i am going to give you the run down of what has happened.
I have recently moved out of home and into my university dorms in which i am using the designated ethernet port to connect to wifi.
When i load up overwatch every other sound is working loud and clear but then when i go to join groups it puts me into one with everyone but my mic is muted.
Even when right clicking the mic there is no unmute option.
I have the right default devices selected as well as all drivers updated.
Please if anyone knows a fix to this problem anything is appreciated.

Hello Lucifer,

To sort try all the steps in this guide here

As of seeing this post i have tried the solutions above and it doesn’t seem to sort out the problem, considering I’m at university could it be down to the ethernet i am using?
