Please help: Omnia 2 won't ring at ALL!!!

[cenozoite]

Everything worked fine until I installed MS Voice command 1.6. At first incoming calls would still ring fine, but then I tried to enable the "announce incoming calls" option and instead the phone stopped ringing completely AND also did not announce incoming calls.

I've tried disabling that option, disabling Voice Command altogether, uninstalling Voice Command completely and rebooting, and all without success. Incoming calls produce no ring sound at all, under any circumstances. I've checked and double checked all sound & notification settings, ring volume, settings etc, and nothing makes any difference. Voice command must have changed some registry setting and I just cannot get it to change back, no matter what I do.

Can anyone help? Is there any way to restore the ring function? The little incoming call window pops up but there is just no ring sound, at all, ever. It works fine when i test/preview the ring under settings, but not when a call comes in!!
