If your ball joints and tie rods ends have no play, your alignment is good and you aren't noticing any abnormal tire wear, I would point you in the direction of your wheel bearings.
When all of the things listed above are ok. A constant humming/vibration sound that gets louder when you turn the wheel left or right is a good indicator that your wheel bearings are going.
