HTC Legend :: Speaker Producing Static While Playing Audio

Just purchased the Legend and there appears to be an issue with the speaker. I want to identify if it is just my phone or if other users are experiencing this problem. The speaker on the phone is producing static whenever audio is being played. It can be heard clearly when doing the following: Click on the volume button on the side (either up or down) and place the phone to your ear. Open the phone application, click on a number and place the phone to your ear. The static lasts for 5 or 6 seconds and then dies off. Would appreciate if anybody with the phone coud check this out as I'm unsure if a return is required.
