Rule in other stuff.
Spoke tension, or rather, difference in tension,
per se does not cause clicking. However, a spoke with no tension, or one with a cracked spoke hole, will lead to clicking.
To completely rule out the bearing, remove the wheel (I assume QR, not TA??) and hold the wheel by the skewer and spin it. The feedback through your hands from the bearing should be smooth and silent. Spin a few wheels to develop a reference feel for a good bearing. I don't expect someone, on their fist spin, to know what feels good and what not. However, once you've spun a bad wheel, you will know.
A bearing does not click once per revolution as one would expect. This is because balls and races don't spin perfectly in sync. A ball actually half-spins, half drags.
To inspect the spokes, pluck each spoke with a fingernail like you would a guitar string. Compare the tone. A very obvious, very dull tone indicates a loose spoke. That could be the culprit. Failing having found that, now carefully inspect the area around the spoke holes in the rim. Look for cracks. A crack is a tick, for sure.
