did you run alsamixer and toggle the mute button on and off ? unless
you do that, the output is muted by default for some reasons.

BTW, if your motherboard has both HDMI and DVI output, usually, you
can get audio from the DVI output too as it pass exactly the same
signal as the hdmi port, only the physical connector is different.

you don't need to modify /etc/asound.conf
