In call static / hissing problem...

[supercoe]

Hi everybody, long time lurker first time poster!

I've had my sprint diamond since release day and love it very much but I've come to an issue that my searching cannot find and answer for.
I started using the included headset today because I found time to play with the FM radio app (awesome!). So I decided to make some calls with the headset to see what it was like and I noticed a background hiss during the conversation.

After some testing it's hard to tell if the static noise is happening when using the phone normally but it is defiantly apparent when using the headset or speakerphone.

The hissing also briefly goes away (for about 2 sec) if you press a number on the keypad. This was tested by calling my land line with the headset on, I could hear the hissing, press a number on the keypad and hissing will go away for a few seconds.

It also does not matter whether the screen is on or if TF3d is enabled.

Currently my phone is setup as such:
Radio: Telus V1.04.05V
Rom: Mighty 4.6 (rocks!)


Curious if any of you are having the same problem or if there is a fix?

Thanks.
