Indicates S/PDIF source number.
Refer to S/PDIF specification IEC60958-3 for
details.
Channel number for sub-frame 1.
00 = Take no account of channel number
(channel 1 defaults to left DAC)
01 = channel 1 to left channel
10 = channel 1 to right channel
Channel number for sub-frame 2.
00 = Take no account of channel number
(channel 2 defaults to left DAC)
01 = channel 2 to left channel
10 = channel 2 to right channel
Sampling Frequency Indicated.
Refer to S/PDIF specification IEC60958-3 for
details.
