If you're hearing audio while playing the sequence, then the track is there.
I'd say it's time to read the Help file, learn the interface and how the program works.
Use the scroll bar on the right to scroll down to your audio.
Its probably mono and the tracks above are stereo.
You can delete all unused tracks and this will put the audio next to your video.
Here is a screen shot I found online:
You can see audio 1 has two speakers to the right of the # 1 meaning stereo, and on audio 4 there is just one speaker meaning mono audio.
