Select the track in Tracks View by clicking on the number at the left.

Then loop straight up to the top of the track list, in the area above, locate the button with the big S in it and hit it.

If you select any track, it will be the Solo'd track.

Click the same S button to return to all track playback, don't forget what you did or you will be back here asking why you can't here tracks anymore...
