I'm unsure why you're unable to reply back to me, but I will engage you the best I can given the info posted.
The volume buttons on the remote are what adjust the sound first off. The remote you should have is at the link below (not sure if you have a different remote you're trying to use):
Secondly if you are getting no sound from any source on the Bose (CD, FM, etc.) then it sounds like the device is defective, or perhaps simply needs to be rebooted.
To reboot the Bose pull the power cord from the wall for 10 minutes, and then plug it back in. This reset its processor and can sometimes cure the issue you're having.
If there's still no sound or control via the remote, then you would want to unplug the unit for a full 60 minutes and then reconnect to drain all residual current from the unit.
Beyond that it would point to a hardware failure internally and this would require repairs made via Bose (since they are the only ones that repair their systems).
