I am trying to use an external cable for sound to a TV. I have a
cable that plugs directly into the computer on one end and a splitter
that goes from the stereo type plug on the computer to a red white
plug for the TV end.

Shouldn't this TV work using an HDMI cable and bring the sound over on
a separate cable. The computer I am using has an HDMI sound driver
problem. I have 3 motherboards and all 3 have the HDMI sound disabled
because the drivers fail to load properly.

The manual pages you've copied, seem to be indicating the two HDMI plugs
have an option.

If the HDMI connection is "all digit", then both digital video and digital
audio will be on the HDMI cable. An example of something that could drive
a signal like that, might be some kind of DVD player with HDMI output.

In addition, the TV optionally supports digital video with analog audio.
You plug in the HDMI cable and get the digital video. But the audio comes
from the red/white plug set just below the HDMI.

There may be something in the TV OSD (on-screen display) to select
either digital audio or analog audio. Sure, the TV could "auto-switch" and
look for the necessary signal, but that might not be very reliable. It
would be better if the OSD has an option to change the configuration.

On a computer, the HDMI comes from a video card or from integrated video.
Most modern video devices, should be able to do digital video and digital audio
across the HDMI. A few years back, some Nvidia cards had a passthru mode that
converted SPDIF from the motherboard, into digital audio across HDMI, saving
Nvidia from having to put digital audio on the video card. The driver situation
was also a bit strange back then, with a RealTek driver being used for the
digital sound on the ATI video cards. As far as I know, both Nvidia and ATI have
their own branded solutions now, and there shouldn't be any goofy details
to contend with. It should "just work" by now. In years past, they had to
scramble to put a solution together (like the "HDCP Ready" fiasco that
preceded the digital audio thing).

If your equipment is more ancient than that, then the HDMI will carry
digital video only. And you will have to use a 1/8" stereo adapter
from Line_Out (green) on the computer analog audio, to
a red/white RCA (Cinch) connector pair on the TV end.
The regular analog audio driver should be good enough in
that case. And then, using the OSD on the TV and selecting
analog audio with HDMI digital video, should finish the job.

In Windows, there should be a Sound control panel, that selects
either the digital audio device, or the analog audio device, for
Line_Out. So you should be looking in there as well, for the right
option. The computer is just as flexible as the TV. The computer
can do HDMI digital video + HDMI digital audio. Or the computer
can do HDMI digital video + analog audio from the regular sound
output. The Windows Sound control panel, allows you to select
how that works.

Sounds nice.

First I'd wonder if HDMI video bandwidth is advantageous over a 15-pin
VGA for source material limitations respective to both standards, and
how that figures as to the panel's specifications. HDMI carrying
multiplexed sound might be convenient if cabling is an issue for other
than a straight shot in, or should alternative source sound generator
piping, elsewhere out, be of dubious properties. Obviously if then
I'm running a sound source synchronized for later, dedicated boxes -
amps, preamps, i.e. - Digital Signal Processors - HDMI television
circuitry isn't going to cut it unless there's provisions for loop-
back audio-out into an additional mix and source receiver. Something
I wouldn't personally care to engage, as I process encoded sound
through a soundboard with nothing more than a dedicated 2-channel
laser optical feed out, aside, I suspect at industrial impediances, of
course, an included array of conventional RCA jacks for the various
"theatre amps," which to my knowledge, on laser carriers, has little
if anything to do with other than sourced stereo imagining audio
conventions. Apart from listening to each wheel on a car discretely
driving off on disjointed speakers from a point of motion picture
renditions, which I have to defer to actually having experienced. In
fact, I couldn't begin to tell how HDMI relates to engineering and
sound channel carriers in Motion Picture 7.1 "Stereo" when applicable
to the greater picture of vehicular undercarriages.

What I do know about sound processors is that once a chip
manufacturer, say C-Media, fails to follow through in coding for firm
and hardware support, their customer support base leave their cards
like hordes of locusts;- conversely, a popularly written and chipped,
once when done and tweaked in right, droves people might buy in
multiples, literally, before they get a chance to screw it up beyond
all belief, say in the latter instance, like anything that rhymes with
SoundBlaster's suite.

The sky is ultimately the known limit to subject an ear capable of
discerning what unfolding wallets lack to conceal;- of course, I
suspect no one famous actually said it.
