In my experience, problems like this are nearly always problems
in software selection of output and/or mixer volumes.
The card that you are selecting there is an HDMI audio
controller, which means that it is a sound card which only
outputs through the HDMI connection going to a TV or video
monitor. Is that what you are expecting?
If, as is more usual, you are expecting to output through 1/8"
stereo jacks to self-powered speakers or 1/8" line-level stereo
to an amplifier, you need to select that sound card and use it.
aplay -L should give you a list of possible outputs, one of
which you can then feed to speaker-test via -D to test.
Then you can set this in /etc/asound.conf as a default. Mine
says
defaults.pcm.card 0
defaults.pcm.device 3
defaults.ctl.card 0
