Hero going into silent mode randomly

[stantheman1976]

I've had my Hero for less than 48 hours and twice no it goes into silent mode for no reason and when I turn silent mode off the sound still doesn't work unless I reboot. Is this a glitch that can be easily remedied or should I take it back. I still have 12 days to decide whether to keep it or not.

mm i haven't heard that before,
how do you know its going on silent, could it jsut be that you are accidently putting the volume down using the side buttons?

No. It is actually in silent mode because the phones says silent is on and I have to change it. Then the sound is still off after that.
