What is your Bluray player, just a normal set top box for a TV? How is it connected to the computer?

OK, your monitor has no speakers, that is why you don't have sound. The computer does not know what you have connected to the monitor, it only plays sounds through the computer. It's like trying to make eggs, but instead of putting them in a pan on the stove, you just put them on a pan on the counter and then turned the stove on. The stove has no way of heating the eggs unless they are connected.
Some monitors with HDMI but no speakers have an audio output you can connect speakers to, see if yours does. If not, you need a monitor with speakers, or as in the post above, a capture card or some way of getting the sound from the player to the computer which can then play the sound.
