Hmm. Sounds like there is something wrong with your phone. I can just about hear it if the TV is on loud.

I've got no idea what the latest firmware version is. I seem to remember there being a newer one but I'm not 100% sure. The only way to upgrade it is to take it to an official Nokia Service Centre. You can't upgrade it yourself even if you do have the correct cable as the firmware isn't available.
