I'll take a look. I never looked at those options AFTER I connected

a break. Let ya know.

I was disappointed. What you suggested sounded reasonable. But, I
still see no 'HDMI' as a choice under Playback Devices. I even
rebooted the laptop twice whilest connected to the TV's HDMI2 slot (My
TV remote allows me to choose the input HDMI). Have to try something
else I guess.

Thanks

Mine doesn't say HDMI either. The bold title is "Samsung" (which is my TV
brand), and the description says "Intel® Display Audio" and under that
"Default Device." I just hooked it up to see.

If you have no other playback device showing, connect to the TV, then go to
Control Panel . . Sound. Right-click anywhere in the Playback window and
check 'Show Disabled Devices' and 'Show Disconnected Devices' and see if
that helps. If no other devices are showing, then you have a missing driver
somewhere. Did you install Toshiba's ATI HDMI audio driver that Paul
provided a link to? If not, I think that would be the next step.

Did I mention I hate sound problems? Grrrr :-(

Sound over HDMI is not in the BIOS.

*Motherboard* sound is in the BIOS.

The motherboard BIOS does not control internal
operations on third-party GPUs.

And the audio *will* show up, when

"ATI HDMI Audio Driver"

is installed. I'm waiting for feedback from the OP,
that this has been done.

And as Andy Burns says, audio over HDMI is "in-band".
If the cable can carry video without making "colored snow"
on the TV set, then interleaved audio can travel there
just as easily.

There might be no audio, if somehow you managed to put
an exotic format on the source end, which the TV could
not decode. But at the best of times, about all you've
got on these machines, is LPCM, and nothing else.
So that is less likely to be the problem here. The
source end just doesn't have that many "free" options,
and exotic formats cost money in the form of licensing
fees. Which is why they aren't more common.

https://en.wikipedia.org/wiki/Lpcm

"LPCM is used by HDMI (defined in 2002), a single-cable
digital audio/video connector interface for transmitting
uncompressed digital data."

I think that can cover as many as eight audio channels.

Mine's the same, with the addition of "Intel(R) Display Audio" written
underneath "Samsung".
I recall having exactly the same problem that the OP is having several
years ago, and I solved it with a driver update.

I'm not too sure how I ended up with the Intel ones; I suspect I simply
clicked driver update for the Display Adaptor in Device Manager. In fact
I'm pretty certain that's what I did.

I have a laptop connected to my TV via HDMI 2 on the latter.
I am playing a video DVD on my laptop. The video displays just fine
on my TV.

The audio, however, is another matter. I have two selections on the
TV for sound, one for TV speakers, the other for my audio surround
sound. Works fine for TV broadcasts. The only sound I can hear from
the DVD in the laptop is from the laptop, not the TV.

Our TVs have a configuration button for "Source"
(e.g. antenna/cable/HDMI). It sounds as if the
arrangement above did not set the TV Source
to HDMI.

Highly unlikely, otherwise how did the video get through?
The OP said it was on HDMI2 channel, so he must have passed that hurdle.

Some TVs have all sorts of options to mix and match.
On some, you can combine video from HDMI, with analog
audio. Such a combination would be useful for older
kit, which does not have audio over HDMI.

Let's hope the OP has read the TV manual.

The thing that caught my attention, is the
missing entry in the Playback control panel,
which makes it kinda hard to play audio over HDMI.
The audio over HDMI driver has to go in first,
then the icon will appear in the Playback
dialog, then we can dream up other excuses for
why it doesn't work.

He says the video is fine, so the TV's Source is set correctly.

Some TVs use the same source for audio that they're using for video,
others allow overriding the audio source.

What a maze of incompatibilities!
I was getting something of a feel for it, though, reading this thread;
http://www.tomsguide.com/answers/id-...dmi-cable.html

I'll go along with your rationale; the audio over HDMI driver.
I suppose that when it gets working and the audio comes out of the TV,
then the laptop audio will be shut off.
I certainly hope so. I spent some time some years ago getting audio from
both TV and PC, and, as you've said, it wasn't worthwhile. In fact it
was a cacophonous mess.

You could try the "ATI HDMI Audio Driver"

http://support.toshiba.com/support/m...eeText=3025646

http://cdgenp01.csd.toshiba.com/cont...ca0083900g.exe

Packages\Drivers\WDM\HDMI\W864a\

%AMD%=AMD,NTamd64.6.2,NTamd64.6.0 Windows8, Vista ???

If you go to the support page for the laptop, you have
to scroll down far enough to see that one.

On the information page, there are other versions of drivers.
The one I picked above, seems to be for Windows 8, judging by
the labeling.

They have a list of previous drivers as well. Maybe this one
will be Win7.

http://cdgenp01.csd.toshiba.com/cont...ca0077200b.exe

Packages\Drivers\WDM\HDMI\W764a\
AtihdW76.inf
%AMD%=AMD,NTamd64.6.1,NTamd64.6.0 Windows7,Vista ???

They sure make it easy to find :-)

have fun,
Paul


I am pleased to report that I have solved the HDMI problem. I have
had an ongoing medical 'caregiver' (me) situation here with my
sweetie, and have not been able to get back to all this until a bit
ago. I looked at your suggested sites, and decided instead to look at
a site to which I subscribe, called 'Driver Agent' to see what audio
drivers were flagged as needing upgrading. Lo there were two, one for
the Realtek, the other for the HDMI. I downloaded and installed both,
then checked the playback devices. HDMI is now there! I set it as
default and connected the laptop to the TV via HDMI2, and now the
sound is getting to the TV from the Laptop. Isn't that great?

Again I thank you for your interests. All of you.

I hope to one day get an answer, as to why
DVD audio tracks must have the volume of the
track recorded so low. There must be a reason,
but I haven't been able to discover it.

So rip it and reburn it cranking up the audio some

I have noticed they're not consistent but seeing as I actually watch
most of them as ripped avi files straight off a pc to the tv using VCL
it's not a problem to adjust the volume on the fly.

I thought he said his graphics card was buggered.
I assumed he'd be using on board graphics instead.
