I cross-associate sound with mouthfeel and motion, though I'm not sure it's synaesthesia as such. No idea if it's consistent or pervasive enough. (Bass flute is the texture of biting into soft dark chocolate; some singers with particularly nasal voices are the texture of running your teeth or tongue across the ridged plastic surface of a lenticular picture, and as such are almost always unpleasant to listen to; the word "bottle" is a small clockwise vertical spiral motion with a short tail.)

I'd love to be able to "see" the visuals with music, but I don't really feel I'm missing out, either; it's its own sensation.
