There is no dedicated lfe track, cos it's in stereo (2.0, not 2.1). Your player has an internal crossover for low frequencies, and should send those low frequencies to the sub. Some players have very limited bass management, mine included. I had to go into my receiver's settings for multi channel input and increase the gain to the sub by 10 dB, and that's when the light on the sub would blink on and I'd get some deeper bass. Give that a try; hope that works.
