The lowpass filter DOES exist and it is enabled by default but the SMD cap is so small (250pF) that it has no effect on sound.
I soldered a 100nF cap for the quick test and it was too much and the sound was completely muffled from the right channel, but it proved my theory.
The SBPro mixer can disable it just like on a normal SBPro card, this works too.
Now the fun part begins, what Cap value will sound exactly the same as the SBPro?
Anyone familiar with the SBPro design especially the components of the lowpass filter part?
Can anyone tech/electronics savvy help me solve this mystery and make the YMF71x card the best card around for dos gaming.
I'll start by soldering some aligators or sockets so I can quickly switch the caps.
