I've heard about that since the day it was announced. As someone who wanted GPU audio processing to happen since GPGPU designs burst onto the scene with the GeForce 8 Series, I say it's about time!
But I also don't want to find myself in the predicament of unable to max out the audio features in any given game because I don't have the TrueAudio DSP...or getting that DSP and then having to give up CUDA, PhysX, ShadowPlay and all those other NVIDIA-exclusive features, along with having to buy a video DAC for my GDM-FW900 because the only cards with TrueAudio support don't have RAMDACs and thus don't have VGA output at all.
That's why I'm hoping for a full-compatibility CPU-based codepath with GenAudio's AstoundSound plugin, even if it is slower and eats up a lot of CPU cycles. Nothing like PhysX, where the CPU codepath is deliberately unoptimized and the fancier effects outright require an NVIDIA GPU for games to let you enable them.
It's easy to give up on CUDA cus OpenCL performance on AMD cards are a few times faster than Nvidia's cards. That's why Apple's using it in its new Mac Pro, and why Litecoin miners are using them to mine coins. OpenCL is the way to go!
As for PhysX, only game significant that uses it is Batman. So easy to give up to.
As for ShadowPlay, that's a feature that matters to like 1% of the gamers. And with AMD card you just get some FPS drop. So not a big deal if you ask me.
What you get instead with the new AMD cards is Mantle(it's gonna matter since consoles are using it), amazing computer performance (a 7970 can kick Titan's ass and more!), and new audio technology. They are way more important than some last gen gimicky features.
CPU based 3d sound positioning is gonna be a watered down version for sure as CPU is just not great at doing DSP optimized tasks. That's why AMD put it in their graphic cards in the first place. Believe me they would totally push it on their multicore cpus if they can. Their octa cores are pretty unutilized most of the time.
But you can't get a high end AMD card right now anyway. Sold out everywhere.
