Motorola Droid Bionic Lapdock Teadown: Unknown chip with markings PJ1196 SX34H

I appreciate the teardown pics!
I recently obtained one of these, and the volume is not controllable under Android ICS.
A speaker plugged into the Bionic's headphone jack is controlled normally from the keyboard controls, however.

One of the things I have considered is replacing the USB audio setup with a standard powered amp that simply plugs into the Bionic's headphone jack instead, so getting a look at how much/little room I have to work with is extremely helpful!

Thanks!

The Atrix Lapdock, the 100 and now the 500 are all different versions.

The 100 caters to multiple devices, while the other 2 are specifically intended for single devices.
