snd-aloop creates a virtual sound card; it is not used with a real sound
card.

To allow a capture device to be shared, you need to use dsnoop. Your
asound.conf already does this.
To allow a playback device to be shared, you need to use dshare or dmix.
(dshare allows to use _different_ channels; dmix allows mixing multiple
sources into the same channels.) Your asound.conf does not do this; it
uses "hw" instead.
