Phone Vibrates for incoming call, but no ringtone

[cosmotion]

Phone: 8525
ROM: WM6
Problem history: Started 2 months after upgrade from WM5
Backed-up using SPB and did a hard reset and problem continues. (Perhaps I backed up and reinstalled the problem as I didn't check for ring before restoring.. doh!)

OK, I know what you are thinking and yes I have settings set for Vibrate AND Ring under sounds and whne I click play for the test sound it rings and vibrates, but when a call comes in it vibrates and a very low hiss comes from the speaker intermittently.
When set to ring only I get only the intermittent hiss.

Any ideas? Thanks in advance.

Had the same problem several times. Has something to do with a registry setting. I think it was a3pw0 and Setacousticparam. Which ROM do you use?
Try flashing updated WM6 ROM.

Double check the volume in the speaker icon at the top of the home screen. I was so used to using the HTC homescreen i fogot and had the same problem after i altered it. Just double check the right hand slider.

I know its obvious so sorry if you tried it

Good luck fella

Hello

Had the same Problem several times and the solution was always the volume slider which was down. I think the HTC Home makes this sometimes automatically when you have a date in your organizer. But I don't have the automatic Profile setting. I don't know how to solve this instead of setting the volume up again.
