Still looking for 3254 AEC Frameworks

Hi,
i downloaded the portable edition of pure path studio and i started to work with the TLV320AIC3254EVM-U board. After some simple test with success now i want to apply for AEC capability from the 3254, but i've only AIC3254 2x1x, AIC3254 4x2x, AIC3254 4x4x, AIC3254 8x4x, AIC3254_LD_1x1x from the Frameworks tree while the "AIC3254 Acoustic Echo Cancellation (AEC)" PDF shows that i have to choose an "AEC version" of the framework, shouldn't it? Where i can find these AEC version for the 3254?
 
I also tryed to download for the Pure path "Home Audio" software, i downloaded and installed it with success but i'm still not able to run it, when i double click on the GDE start icon software tell me: 
"Impossibile trovare una parte del percorso 'C:\Program Files\Texas Instruments Inc\PurePath Studio (Home Audio) MiniDSP 5.95\ComponentCache\Ntons\Singletons.xml'"
 
Hope you can give me the right direction.

    Hi, Vincenzo,

    Unfortunately, we are no longer supporting AEC on this (or any of our miniDSP) device.

    I am not sure what PDF you are reading. If you can post the title and/or literature number from it, I can get that fixed so as to not cause others confusion.

    Hi d2.

    Does this because miniDSP doesn't have enough resource to support AEC function?

    Does TI provide any substitute AEC solution for AIC3254?  Or recommend other similar TI product for AEC?

    Hi, HL,

    The AEC we used to support was specific to mobile phone applications. We saw too many people trying to make it work in applications where it could not be successful due to resource limitations of the IC (as you mentioned). So, we removed support from this from our tools so people do not end up thinking it will work in their application.

    Unfortunately, we do not have a replacement for this function in our group.
