No Sound Asus MX279 Monitor hooked up to MacBook Pro

Just purchased an Asus MX279H monitor to connect to my 2012 MacBook Pro (OS 10.9.4). I'm using a 10ft DisplayPort to HDMI cable from CableMatters. Picture display is working great, but I cannot get the sound from the monitor speakers to function. The audio output cable to headphone jack doesn't work either. I've even tried to configure the audio device via the Audio MIDI utility on the MacbookPro. I can test the monitor speakers via this utility on the computer, but still cannot get the computer output to communicate with the speakers. Is it the cable? Or something else? I thought a cable would be a better option than using the VGA to DisplayPort Adapter. Maybe I'm wrong?

Thanks for any suggestions!

MacBook Pro, Mac OS X (10.7.5), iTunes 11.1.3

Hello kmb1,

Thanks for using Apple Support Communities.

Your computer does have the capability to transmit audio from its Mini Display port to HDMI. Have you changed your audio output settings in your system preferences at all?

I think most of my problem might have been human user error. I finally turned everything off, unplugged everything and started over. It all seems to work now! I did change my audio output as well. Thanks.
