Audio and HDMI?

I ask out of ignorance mostly -

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.

I thought the HDMI would carry the sound to the TV. Shouldn't it?
I am not surprised that the sound does not convey to my surround
sound, but I want to be able to increase the sound volume beyond the
limit of the laptop. If I could get the sound to come from the TV, I
figure I could do that. As it is, I cannot.

Am I missing something here?

Anyone?

Thanks

The key to using audio on Windows 7, starts with the icon in the lower
right corner. Right-clicking it, offers things like "Playback" or
"Record" as sub-panels.

In there, you can select HDMI as the output path. In this example, you
want the top item, and want it to be the default.

http://www.reviversoft.com/blog/wp-c...trol_Panel.png

In that diagram, there are a grand total of two audio chips.

video card --- "AMD HDMI Output"

HDaudio chip --- (analog Front port) --- Speakers
--- (analog Headphone port) --- Headphones on front
--- (digital audio S/PDIF) --- 75 ohm RCA connector, to AV receiver
--- (digital audio S/PDIF) --- TOSLink red LED output, fiber cable to AV Recvr

On some laptops, the analog headphone connector, is "coaxial" with
the TOSLink red LED output. Looking in the barrel of the headphone
jack, for a glowing red color, tells you that you have TOSLink.
This is only of use to you, if you have an AV Receiver with
a TOSLink input.

So those are the five items in the example. A driver like
RealTek HDAudio, would handle the bottom four. The AMD/ATI
video driver, would have an HDAudio driver for the video
card over HDMI path.

The controls for the audio, start with that icon in the
bottom right. And you can continue drilling down in
there, until you find the control you need.

If you install a proprietary driver, like install RealTek
driver, that gives yet another control panel to look at.
A more "traditional" looking control panel. Sometimes
there are more settings in there, such as swapping
Center/Sub wiring and so on. Or enabling Microphone boost.
The trick in that case, is figuring out which EXE in
the installed software, is the one for the control panel.
As Microsoft is on a mission to use "generic" drivers
where possible. While users will still try installing
the driver off the hardware web sites.

I don't see any HDMI under sound. Maybe that's my problem.
I have a Toshiba Satellite L775D with W7 Home Premium SP1.
and Realtek HD audio.

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.

They sure make it easy to find :-)

have fun,

Is it just when watching DVDs, or is it all AV? For example, what
happens when you're streaming video from the internet - does the sound
for that get to the telly?

I've got a Samsung laptop running W7 Pro, and when I connect that via
HDMI to a TV, the TV shows the video *and* plays the audio without my
having to change any settings.

Could the cable be duff? Have you tried a different one?

On my system running W7 Home Pre. I have both the Realtek onboard sound
and AMD HDMI output from my video card. I don't have anything HDMI to
connect it to so I've not tried and it displays "No Connection" so it
won't switch even if I try. I assume that if I did connect it to
something suitable I'd have the option to select it rather than the
Realtek for sound and I'd no longer hear sound out of my speakers but
rather the tv (or whatever). That's certainly how it works doing
recording as I often switch between an analog mic and a usb mic.

You can select output device by right clicking on sound icon on taskbar.
I get "Open Volume Control", "Playback Device", "Recording Device",
"Sounds" and "Volume Control Options" as selections.

If that doesn't work have you perchance insured it's not just a cheap
cable doesn't have the cabling for sound, e.g. check using a known
working cable. And for that matter does your tv have sound using some
other device connected via HDMI?

Try driver updating with your TV connected.
Device Manager, Display Adaptor.

What works on my Acer is to hook up the laptop to the TV (via HDMI, of
course). Right-click on your volume control, select Playback devices, and
you'll see another device other than your "normal" speakers. Click on it.
then "Set as default." You may have to restart the laptop, but leave it
connected to the TV, and leave the TV on. Then the sound will play through
the TV only until you disconnect the HDMI cable. Then the sound will revert
back to the laptop speakers, but will play through the TV automatically*
when you reconnect the TV.

*On my Acer, I sometimes have to reboot it to get it to play again through
the TV, but I don't have to mess with the settings any. That may be a Win8.1
thing since it did it automatically when I had Win7HP x64 installed on it,
and it also changes automatically on my old Gateway with Vista.

Anyhow, that's what worked for me.

I'll take a look. I never looked at those options AFTER I connected
to the TV. Maybe then, unlike before, HDMI will show up. That wud be
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

No. Streaming produces no sound either.

My TV remote allows me to select the HDMI source (of which I have
three, counting HDMI1 FIOS broadcast).

Could the cable be duff? Have you tried a different one?

It is a new HDMI cable - I have now tried two cables with same result.

Thanks anyway.

It is a cheap HDMI cable. Only one I have right now that I can try.
If I buy another on the web (Ebay or whatever), it will take at least
a week or so to get. I do have a VGA/HDMI adapter cable I could try,
but I didn't do that because I figured the laptop's VGA wudn't carry
sound anyway. I guess it is possible the laptop's HDMI has to have
something special to carry audio. Also, I have a secondTV with HDMI
inputs. I think I will try connecting the laptop to it next on the
chance that it would work.

Monoprice.com is usually the go-to source for Cables.

Are you an Amazon prime member? When I priced HDMI cables there, they
were not much higher than Monoprice, and with Prime there's free two-
day shipping.

I can confirm that HDMI cables are supposed to carry sound. An HDMI
cable is the only connection between my DVD player and my TV, and the
sound is fine.

BTW, "cheap cable" is not necessarily a bad thing. While it's
possible your cable is bad, the general run of cheap cables are just
fine. Don't believe the hype about gold connectors from companies
like Monster.

If the cable works for video, there's no need for a new cable. with HDMI
the sound isn't carried over dedicated audio pins, the sound data is
interleaved with the video data on a common set of pins.

I tried the second TV, with the same result - no sound, and no HDMI
presence under the laptop's W7 sound. Still could mean that the HDMI
cable is bad or at least does not carry audio. Hate to buy another
just to test that.

Thanks
