Try this:

Navigate to the following registry key:
HKEY_LOCAL_MACHINE\Software\HTC\PHONE

Locate a registry entry named FaceDownMuteRing.

FaceDownMuteRing has the value of 1 by default (enabled). To turn off and disable the mute call on phone face flips down feature, set the value for FaceDownMuteRing to 0 (disabled). Soft-reset.

By the way, this tweak needs to be done if you want your phone to automatically switch to speaker when you place it face down. That was a feature on stock ROM but it does not work on R1 or R2 unless you do this change above.

Not true, speaker switch and red LED are working fine without a tweak, but I haven't installed any carrier cabs.
