Audio Systems: Audio system connection to tv, antenna cable, screen menus

Question
QUESTION: We're trying to hook up a TV for our kids to use for their gaming systems and
home sound system.  We had a different TV hooked up before.  This one's newer
but doesn't seem to have audio out - as the previous TV did.  It only has video
and audio in.  Is there any way to hook up a sound system to this TV?

ANSWER: I need more information about the TV if I'm to give you an educated answer. I will say that if the TV is fairly new then there is a good chance that it has a 3.5mm mini jack somewhere on it. If you have the manual you should check it.

QUESTION: Thanks for your quick reply.  I've checked the tv and we don't have any other
input/output options.  I found this answer from a fellow expert, and can
make this work, except for the gaming system.  Not quite sure how that can
fit into this configuration:

The solution to your problem involves purchasing two pieces of equipment:
an audio/visual receiver and a DVD player. You connect your TV's incoming
signal, which will be coaxial cable feed from an antenna, cable or satellite, to
the ANTENNA IN connection on the rear panel of the DVD player. You connect
the ANTENNA OUT of the DVD player to the ANTENNA IN on the TV. You
simply direct the audio and video throughput of the DVD player to a discreet
source (VIDEO 1, VIDEO 2) on your receiver (the user's manual will walk you
through the set-up and designation process, generally through on-screen
menus), and every time you have the receiver on and the correct source
selected, you'll hear the TV's output over the receiver's speakers.

Now, very few TV broadcasts are in surround sound, and you generally need a
cable or satellite connection to receive them. Check with your cable or
satellite provider to find out if you need anything special to accept broadcast
surround sound. I would think not, but it's worth a phone call.

However, any DVD will play in surround sound, and every A/V receiver made
these days has at least 5.1 capability (two front channels, a center channel,
two surround channels and a subwoofer) and can handle virtually all the
standard surround decoding algorithms (DTS, Dolby, and their variants).

Thanks so much -  

Answer
Sounds to me to be a little presumptuous, unless he knows that you don't have any of the peripheral equipment he is recommending. Any sound system, be it surround or an older amplifier and speakers will work if you just want to get sound and not have the surround bells and whistles. It's really for you to decide how much you want to spend and what is your criteria. Professional audio is my expertise. I need to know all available options to get a system to work even if it's temporarily. The best way you can achieve what your looking for is to decide what your expectations are. The more information you give an expert the more educated his response will be.
