Mac Pro to TV - No Audio

I have an early 2009 Mac Pro tower (specs: Mac Pro (Early 2009) - Technical Specifications) and I am trying to connect it to my Sharp Aquos (2008-ish). Currently, the picture is connected and displayed via DVI-to-HDMI cable. I know that DVI does not carry audio so I have tried, but with no success, 3.5" audio cable from tower-to-TV, stereo cable from tower-to-TV (left & right) and optical audio cable.

Does anyone have any possible solutions for me? Should I simply use the PC Input on the TV with a DVI to VGA cable and regular 3.5" audio cable? Has anyone had any success using the TV speakers for audio?

Please help! Thanks!!

PowerMac, OS X Yosemite (10.10.3), null

You could try this: Go to System Preferences —> Sound and click on "Output." You should see your TV as an option. Select it as the device to which you want to direct the audio, using the stereo cable with the 3.5mm plugs or the one with the L & R RCA-plugs.
