Same with digital audio input. It would be a great feature to choose from different audio inputs (line in, coax) for recording purposes or to use it as a preamp for analogue oder digital sound inputs.
I have manually installed the “Waveinput” Plugin for Squeezeboxserver. However, this did not work, since there is no option to change/choose different audio input. The waveinput plugin seems no more compatible with curent hard-/software, probably that’s why it is no more listed in the plugin list of Squeezboxserver.
Other question: does the curent Kernel work with the “old” original Wolfson audio card?
