hmm... may I ask what's wrong with Yamaha DAC in SGSII?

Ok I explored about everything. Clocks, Master/Slave, Effects. I now believe Yamaha messed up by designing a defective DAC for Samsung.

I'll finish writing my analysis so this won't be just words but proved facts, and don't plan to work more on the audio topic for #GalaxySII

Flawed, end of story. I'll still explore the external USB DAC option, but nothing related to the Yamaha MC1N2 unless they fixed themselves

If Yamaha manage to fix it, IMO it will be by the guy who designed the chip or an insider guru knowing everything about it.

To my limited comprehension there is a flaw in an internal resampling/oversampling algorithm. Cannot be modified via this driver.

Of course you need to relativize what I say here. #GalaxySII sound is probably better than most other Android phones. But not iPhone or SGS
