I could have sworn that the volume sliders tend to be at zero by default
but I do not remember channels being not muted. You had already
mentioned increasing the volume levels, therefore I initially focused on
(re-)checking the order of your cards, which is the other common cause
for "no sound" even though the relevant modules are loaded.

The commonly-cited reason for having zero volume by default is to avoid
accidental damage to the audio equipment and the ears of the user. The
idea is that you can start something like speaker-test and then
gradually increase the volume levels until they fit your equipment and
personal preferences, without running the risk of having too high a
volume at any point. This default behavior causes a lot of confusion,
unfortunately.
