Thread: Realtek ALC888 chips give a different sound. Why?

Just interesting. There are 2 motherboard. Both for the sound with the 888th. The difference in sound really felt at the hearing ... from the more expensive mother sound much cleaner. Even compared with an average hands (Creative Live 5.1) and the other sound is a much less ... interesting how so? Chips are identical. Acoustics is the same. Settings are not changed.

In the formation of sound is involved not only has the sound chipped. Of hinged elements around the chip assembled circuit binding, which forms the envelope and the filter frequency response (smooth) the output signal. Since the scheme can expect the developer of their choice (the filter can be a normal RC, and possibly third-order), as well as an analog signal is still dependent on the quality of installed components (even passive, such as resistors and capacitors) - the signal to output can greatly vary. And given the interference of food, resulting in checkmate. Board and the complexity of filtering - this is you, and very different sound on the same chip, but on different motherboards.


If that is so interesting - try to find the Datasheet for this chip, where even in the model will include several versions of varying complexity, even with different parameters. And that the developers of mat. Plat invent - and not had a horrible dream.
