Changes needed for AMD64

This is awfully unpleasant. There's no guarantee the value of this variable is a package in this recipe, though it does seem likely, it's not guaranteed. If necessary we can merge this as is as a temporary solution, but this is far from ideal. A better bet would be to separate the asound.conf package from the rest and include both alsa-states and the config package in the virtual-runtime, or explicitly pull the config in via another means.
