What speakers are you using with your Codec Plus?  Are they capable of emitting the ultrasound signal that is required for Proximity to work?  Or is there any other DSP in your room that is perhaps removing the high frequency signals from the audio?

I'd also recommend that you update the software on your codec as the version version you have is over a year old.  The current software release at the date of this post is CE9.9.1.
