+ *  2: 176.4-192.0 kHz then snd_efw_hwinfo.amdtp_XX_pcm_channels_4x applied
+ *
+ * The number of PCM channels for analog input and output are always fixed but
+ * the number of PCM channels for digital input and output are differed.
+ *
+ * Additionally, according to "AudioFire Owner's Manual Version 2.2", in some
+ * model, the number of PCM channels for digital input has more restriction
+ * depending on which digital interface is selected.
+ *  - S/PDIF coaxial and optical	: use input 1-2
+ *  - ADAT optical at 32.0-48.0 kHz	: use input 1-8
+ *  - ADAT optical at 88.2-96.0 kHz	: use input 1-4 (S/MUX format)
