Kinda of awkward in Linux but givin it a try. Using Mint 16 , use it for paying bills and such and I use XP for Netflix and Amazon Prime viewing. Managed to get Mint to recognize my ATI HDMI and load it at boot but haven't gotten sound over to my TV. When I toggle "Builtin Audio Analog Stereo " videos play in utube but with no sound to my TV via HDMI cable and thats expected . When I toggle HDMI Audio , in output device , videos play really fast with no sound . Seen variations of this theme on the net , tried uninstalling and installing Flashplayer still the same . Any insight appreciated .

Hi & Welcome to Linux Questions-

So...you don't have any sound to your T.V.

Is the T.V. what you are using for your monitor?
Does you pc have speakers?

If your running Ubuntu try raising the Master, PCM, volume and raise up all of the column's in 'alsamixer' and see if that gives you sound.

To find out what sound card you have you can run the above cmd that EDDY1 posted for you. You can run this too and it will work as well.
