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 -dsr-
