Add the capture pcm only if there is at least one ADC configured in the SYSCONF register.

1 : 0;Are you sure that this is correct? I thought the value 0 means 1 ADC, 1 is two ADCS, etc.
I think it is correct. This is what the datasheet says:
CCS04: System Configuration Register
bits 3:2
00: one stereo ADC connected 01: two stereo ADCs connected 10: one stereo ADC and a S/PDIF receiver connected 11: No physical inputs
I have two soundcards, one with 10 (ADC + SPDIF in), another with 11 (no ADC), the code seems to work fine.
Thanks,
Pavel.
