Comment:

 Alsa is already able to do stereo playback and capture out-of-the box
 without a alsa.conf file. The problem is that those cards are not stereo
 sound cards but audio cards with two or more independent input and output
 channels which can be flexibly mixed. Pulseaudio can't handle this while
 alsa can, even if envy24control from alsa-tools is needed for mixing and
 setting the volume. Of course these independent channels can be set to
 just play and capture plain stereo, but they can do a lot more.

 Setting such an alsa.conf which imitates a stereo sound card on those
 audio cards is just a dirty workaround for pulseaudio, but definitely not
 a fix for pulseaudio. This needs to be fixed in pulseaudio itself, not in
 alsa.

 Btw., this alsa.conf hack probably removes some of the features of those
 cards.
