DAC parameter setting introduction:
IN: I2S/DSD/SPDIF settings select DAC decoding board I2S, DSD, coaxial (coaxial) three input sources
I2S: 3-L/4-L setting 3-wire I2S (without MCLK) or 4-wire I2S (with MCLK), Raspberry Pi 2B/3B/3B+needs to be set to 3-L; The Raspberry Pi 4B can be set to 3-L or 4-L (with MCLK master clock required)
MCLK: aut/128/256/512. When the I2S setting is set to 3-L, set the multiple relationship between the recovery system master clock (MCLK) and the sampling rate FS. Aut is in automatic multiple mode, with 256FS below 192K and 128FS
BIT above 192K: 16R/24B/24R/24L/32B. When the IN setting is I2S, set the bit depth of I2S input/output, where L/R represents left aligned/right aligned format and B is the standard I2S format. (Note: The input and output formats of I2S are consistent.)
1B:When the IN setting is set to DSD, the bit depth of DSD is set to 1B and cannot be changed
16R/24B/24R/24L:When the IN setting is SPDIF, set the bit depth and format of I2S output for 16R/24B/24R/24L
FLT: 1/2/3/4/5 Set the filter type used internally in the PCM5122 DAC decoding chip to switch between different timbres
SPDF: turn on/off coaxial interface output function
RCA: Turn on/off the analog audio interface output function
OPT: out/off Enable or disable fiber optic interface output function
I2S: turn on or off HDMI interface I2S or DSD output function
