Sound - high pitched sound, sudden loud noises. Things like motorbikes, kids shrieking, car brakes - these are literally painful. I have hyperacusis. Difficulty making out speech and coping with background noise/speech, being easily startled by sudden loud noises.
Touch - don't like social touchy-feely, don't like being poked. Need to wear soft fabrics, scratchy, coarse fabric, lace or labels and seams drive me mad.
Taste - no particular sensitivity, in fact I love spicy food! Texture can be a problem, though - if I don't like the texture, I can't eat the food, no matter how tasty it is.
Lights - not a huge issue for me, but I do have the following issues: if I'm out in the sun for a long time without sunglasses, if there is a lot to take in and a lot of activity, by the end of the day, I develop a headache and sometimes feel sick. Glare is painful and difficult to tolerate. I also feel tired and need to lie down indoors. Sunglasses definitely help, I feel less stressed, too. I'm not sure if this is a sensory issue or not - could also be a migraine.
Also, I have the following issue: Some TV shows are impossible to watch because of the special effects - flashes, white screens flashed at you between shots, or flickering. It's painful - makes me feel dizzy like I have vertigo, or kind of panicky and I need to turn away. It's not just the image that gets me, also the sound that accompanies it. Not sure if this is a sensory issue, or a problem with my eye muscles being slow to react and to adjust to the sudden light change, or the quality of the light emitted by the TV or computer screen. (I don't automatically assume that what I'm experiencing is an autism-related sensory issue, I look for other possible causes too, and then rule them out).
Contrast - bright lights, especially at night. Bulb or LED lights emitting white light - can't tolerate them and need to wear sunglasses. Awful things!
