You can assume all you like. But its a driver issue, audio-caf problems. TeamChopsticks has been committing like madmen, problems will be fixed before you know it.. Also this is built from source not ported from some other device.Just finished flashing. All I have to say is that it's excellent for a pre-beta/alpha release but the lack of sound kills it for me. (AOSPA 3.90 Linaro also had this problem so I'm assuming this is caused by some code missing in the current 4.3 builds ported to hercules that accesses the speakers and headphone port)
