TV SIF = Sound Intermediate Frequency stage.
TVs receive a broadcast signal, which is a different RadioFrequency for each numbered channel. The tuner takes the signal and changes it (demodulates) to an Intermediate Frequency, so that the rest of the TV's circuitry can deal with it. The intermediate frequency is always the same for any given channel. After the tuner is a stage where the intermediate frequency is split into Sound IF and Video IF, which are then sent on to their respective circuits. If I have to type any more you need to pay up.

SIF and VIF are the product of the tuner unit which simply put , the TV station is selected and tuned and then converted to a much lower frequency called IF or intermediate frequency ( not demodulated Jimbob ) the sound IF is then separated from the VIF and then the two signals go there separate ways, VIF end up at the pic tube and the one your question relates to ends up at the speaker, of course before it can drive a speaker it gets amplified then the sound is separated or detected ( or demodulated Jimbob ) from the radio frequency component and after which it is known as audio it gets more amplification as audio and then is applied to the loud speaker. After all this asker I hope you have the gen idea , the better answer to your original question covers a few chapters in a text book so my explanation is like the condensed version but still accurate .
