What audio chip is the new HTC ONE using?

I heard that the sound quality on the one x was lacking compared to the gsIII becase the SIII went with the wolfson dac, what about the new HTC ONE?

Don't say it has beats, that's just branding, it's meaningless. We have reports on speaker quality being quite good, but what about headphone jack quality?

What DAC are they using? How does it compare to the wolfson dac?
