I think you need to go back and read and actually understand what they are talking about. Pay attention this time, during the press conference Cerney said nothing about sound processing. 

http://www.gamechup.com/mark-cerny-ps4-contains-a-dedicated-audio-processing-chip/

“There’s dedicated audio hardware,” he revealed. “The principal thing that it does is that it compresses and decompresses audio streams, various formats. So some of that is for the games – you’ll have many, many audio streams in MP3 or another format and the hardware will take care of that for you.

“Or, on the system side for example, audio chat – the compression and decompression of that.”

He also added that the GPU can be useful to do different types of audio processing.

“It really does come down though to the amount of parallelisation that is natural to perform for that algorithm, and that does vary greatly depending on what you are doing specifically in your audio processing. I think that as you go forward we will see a hybrid approach in a couple of years where certain aspects of the audio are being done on GPU.”

Earlier he revealed that PS4 GDDR5 RAM latency was not much of a factor since the GPU could handle it.

Again, it's right there in yet another article, He's saying the GPU can be useful in some types of audio processing like ray casting. Not that Devs  need to use the GPU for sound processing.

So before you respond with another "good luck with that" comment, you should provide a source, cause right now it seems you don't know what you're talking about.

Baha! Thanks, someone was asking for the GPU sound reference.  I think they thought I was making it up to make Sony look marginally competent.

So the one advantage is has, a more powerful GPU, they ruin that as well! 

Good job, Sony, Cell 2.0 here we go.

Sigh, thinking of my story about the cousin that boast about doing great, then somehow, always messes up.

Here is an interpretive dance using the football medium to interpret my statement.

WTF do you want to day? I can't understand.

PS4 have a audio processor too... it was reveled in February... what the Cerny said that can be done on GPU is Ray Casting Audio but that's even the audio processo in Xbone can't do.

You really don't understand do you?

You really don't have a sing bit of understanding what cerney is talking about. And it clearly shows. Not only do you not understand you have yet to post a source that back up your claim. I'm done with you till you can have a resonable converstation about the topic. 

What exactly is the problem?
