I've had a look at the manual for your machine and that's awkward as the only HDMI connector on your device is an HDMI Output.
This pretty much a standalone Blu-ray system as you've no video inputs at all but you do have two optical inputs for sound.
Do you have an optical out connection on your TV?
Bear in mind some TVs allow you to change whether the connections are inputs or outputs via the TV's menus.
My own TV is like this and prior to getting an HDMI A/V Receiver I had the Xbox 360 connected to the TV via HDMI and the optical connection from the TV to the A/V Receiver.
If your set up works like this then you can connect all your devices to the TV and send the sound via the optical link.
If you haven'y got enough inputs on your TV then you can buy either a manual (with buttons) or autosensing HDMI switching unit that connects multiple HDMI inputs to one output
Something like this for example which is a pretty small autosensing one but there are plenty of other types that offer more inputs if required.
