[ALSA] Enable capture from line-in and CD on Revolution 5.1
Enable capture from line-in and CD on the Revolution 5.1 card. This patch adds support for switching between the 5 input channels of the AK5365 ADC and modifies the Revolution 5.1 driver to make use of this facility. Previously the capture channel was fixed to channel 0 (microphone on the Revolution 5.1 card).
