FM Radio without Internet?

Is it possible to use FM radio WITHOUT internet connection or special devices ?

No. Best option is to get a FM-radio tuner. There are USB versions of such tuners though most are TV tuners with an added FM radio tuner.

And gnomeradio is a piece of software for that:

Oh I know of 1 notebook with a 3.0 x FM antenna: Toshiba Satellite A305-S6863.

The FM-Radio works because there is FM receiver (hardware). So you need a FM receiver first in notebook. Most of notebooks doesn't come with FM receiver.

It is just not the software part.

You can get a USB FM receiver and use it. After that can have a look here - Is there any good software for Linux for FM radio listening?
