"FIXED", with the understanding that I tricked the X server with the xrandr
command, then kill and restart an X session:

X & xrandr -d :0 --output HDMI-0 --set audio auto
kill $(pidof X)
xinit xbmc-standalone ...


Though, it would be great if audio would automatically work without the need of
the xrandr command.
