Does the Eee Pad Transformer TF101 support the APT-X audio codec? I am considering buying a Bluetooth speaker for use with my Asus Transformer (amongst other devices) but I am unable to find out whether the Transformer supports the APT-X codec, or find any information as to whether this question is actually appropriate as I may be mixing my terms/getting confused.

I am considering a device such as this:

Creative ZiiSound D5

What I am wondering is whether the Transformer will be outputting the sound using the APT-X codec or not? Is there any way to determine this?

From the specifications of the Transformer here the Bluetooth is Bluetooth V2.1+EDR.
I doubt it, since it's proprietary; Android by default only supports these codecs.  It's not required for the speakers to work though, as far as I can tell.
