Bloody Marvelous

One of my first stages starts whistling when I go below 13m.
I tried breathing slow, that reduces the noise level, but prolongs the whistling.
I tried inhaling sharply, but that just makes it really loud.
It also whistles when I use the inflator.
As soon as I ascend above 13m, the regulator is dead quiet again. Drop below 13m and it starts whistling again.
I just certified for Sidemount, but I can't dive with a whistling 1st stage. It's annoying as all heck and it bothers the other divers.
Is there anything I can do in the field to fix the issue, outside of getting it serviced?
(Not that I think it matters, but the regulator in question is an Apeks MTX).
