DAC parameter setting introduction:
INI2S/DsD/SPDIF settings select DAC decoder board 12S, DSD, coaxial three input sources
I2S: 3-L4-L set 3-wire 2S (no MCK or 4-wire 2S with MCLK, Raspberry Pi 2B/3B/3B+ needs to be set to 3-L; Raspberry Pi 4B/4B+ is set to 4-L, which is also OK Set to 3-L
MCLK: aut/128/256/512 When the 2S setting item is 3, set the recovery system master clock (the multiple relationship between MCLK and sampling rate FS, aut is automatic multiple mode, 192K is 256FS, 192K is 128FS
BIT: 16R/24B/24R2432B When N is set to 12S, set the bit depth of 12S input and output, LR stands for left-justified/right-justified format, and B is standard 2S format. (Note that the input and output formats of 12S are the same)
1B When the IN setting item is DSD, the bit depth of DSD is 1B and cannot be changed
16R/24B/24R24L When IN setting item is SPDIF, set the bit depth and format of I2S output
FLT: 1/2/3/4/5 Set the filter type used internally by the PCM5122DAC decoder chip to switch between different tones
SPDIF: OUT/OFF turns on or off the coaxial output function
RCA: oUT/OFF turns on or off the analog audio output function
oPT: OUT/OFF turn on or off the optical fiber output function
I2S: OUT/OFF turns on or off the I2S or DSD output function
