Audio ground & digital ground should be connected at one point, either at power connector or underneath Audio DAC. 2. For EMC consideration, all power supply lines should have serial ferrite beads, laid as close to the chip as possible. 3. All the clock signals should have contain 33 ohm serial resistors, as close to the source as possible.
