That looked promising: Supercurio, French developer of famous Voodoo Sound bought a GP 4.2:
After receiving a lot of request to support Galaxy Player lines I decided to buy a Galaxy S Wi-Fi 4.2 in order to provide a quality Voodoo Sound support for this device.
Unfortunately it seems the 4.2 is not good enough for that project
Eww just noticed, a required kernel config option (KALLSYMS_ALL) is missing which make the port hazardous.
Maybe it will not be possible eventually.
So to be clear, its possible it won't happen. I don't know yet.
Listening tests gave me the impression it doesn't sound as good as I expected from this codec so I didn't wait and measured the output.
THD and IMD+Noise levels are the highest I found on any WM8994 / WM1811 device so far, jitter is present too.
0.017% THD instead of 0.011%
0.019% IMD+Noise instead of 0.012%
.. and that's enough to sound off to my ears.. f*ck my life.
Moreover he got a faulty device with only one speaker working so:
I'll ask the seller a return & refund, sorry guys − project canceled so far: FAIL on each most important requirements with this device, I'm disappointed
Thus the GP 4.0 (YP-G1) remains the only voodoo-compatible Galaxy Player. Too bad
