Yes but what's is function in the CPU and the I2s design in how it relates to the frequency in the signal being transmitted into the DAC. I believe that’s what it’s doing. The I2S is all encompassing with clocks and signals, data. It gets decoded but the I2S the only way to decode DSD without a HDMI cable in SACD because Sony has copyrighted its use. If for instance you get a SACD player it can only transmit the digital signal over HDMI but that’s not the case with I2S It doesn’t convert DSD only PCM.
