which playback device is analog or digital

you need to add the device number of digital device into 
USB-Audio.pcm.iec958_device if device 0 is not the digital device

# If a device does not use the first PCM device for digital data, the device
# number for the iec958 device can be changed here.
USB-Audio.pcm.iec958_device {



there are two capture devices

you have to ask alsa devel how to fix this if device 1 is not digital since the
above changed the digital input device
