| D | cmipci.rst | 113 The CM8x38 provides the excellent SPDIF capability with very cheap
116 The SPDIF playback and capture are done via the third PCM device
117 (hw:0,2). Usually this is assigned to the PCM device "spdif".
132 The playback and capture over SPDIF use normal DAC and ADC,
136 To enable SPDIF output, you need to turn on "IEC958 Output Switch"
140 The SPDIF input is always enabled, so you can hear SPDIF input data
144 You can play via SPDIF even with the first device (hw:0,0),
145 but SPDIF is enabled only when the proper format (S16LE), sample rate
154 output through SPDIF. This switch appears only on old chip
157 Note: without this control you can output PCM to SPDIF.
