In my case, alsamixer shows Intel 82801DB-ICH4 uses Analog Devices AD1981B as AC'97 Codec. Chip spec may serve as a reference. http://www.analog.com/en/prod/0,2877,AD1981B,00.html It uses two ADC circits , which can be shown as ADC and ADC2 in the '/proc/asound/pcm' And have one SPDIF port.
What is the port of SPDIF connected to in your board of PC ?
