Depending on the design here,
I made a ALS100 pc104 sound card.
(Respect to the original author for opening up the design data.)
It works well.
But there's some noise in it.
Please give me an idea to reduce the noise.
It doesn't look like you're generating a new power rail for the analog side and it doesn't seem there are layout considerations to separate analog and digital sides. Linear regulator on 12V to make an analog 5V rail should help a lot already but any other stuff will come from physical aspects and control of ground currents etc.
