There are many ways to do this. If you have a VCR / DVR / Cable box, you can 'split' the signal - cable goes into the VCR/DVR/Cable box, then the video out from this device goes to the TV, and the audio out goes to a audio receiver. Whether it is HDMI, optical, component, or plain old RCA, it shouldn't be a problem to do this. Many modern TV's even have an 'audio out' capability.

For your application, you can use any radio which has "audio in" ability - like a Bose Wave radio or any mid-range bookshelf system. Connect it to the TV and/or cable box, and you should be good to go.

Post up either the model number of the TV you're working on, or a picture/diagram of the connections available in the back of the set.

BTW: Home theature setup 101: when connecting a 5.1 or 7.1 audio system to a home theature system, it is best to turn off the speakers built into the TV - otherwise it distorts the full 5.1 or 7.1 dolby digital audio.
