Under System-Sounds I show:
Under 'Playback' headphones is flagged green with 'High definition

If you're having trouble finding the (now non-existent)
spec page for the A630N, you could take the side
off the computer, look at the motherboard, and see if
it has any identifying marks.

http://support.hp.com/us-en/document/c00196251

For example, on that Asus PTGD1-LA made for HP, the label
between PCI slots identifies it as such. You can see
it in the picture. There are some white letters, between
the first and second PCI slots. Having a secondary
identifier like that, can help you in your search.

That example uses RealTek HDAudio.

If your sound was Realtek, that manufacturer happens to
offer very nice driver files for both AC'97 and HDAudio.
This is unlike other brands of audio (Sigmatel/IDT) where
you'd be better off using the HP site for the driver.
RealTek has their own nice website. Some other sound chip
makers, like Analog Devices, they make you go to your
computer manufacturer for actual driver distribution.
RealTek is one of the exceptions.

http://www.realtek.com.tw/downloads/...vel=3 &Conn=2

On modern OSes, it's possible for the OS in-box "generic"
HDAudio driver, to provide a working LineOut. What the RealTek
driver can provide, is additional support, such as a
software DSP equalizer, or provide support for certain
telephony options. You also get the surreal RealTek
control panel to play with :-) (It didn't always look
that goofy.)

Of the two impedance sensing methods, RealTek lacks actual
load sensing, and detects that you've plugged something in,
only if the motherboard jack has "side-contacts". It sometimes
happens, that the jacks on the front of the computer case,
are AC'97 type jacks, and don't have the side-contacts needed for
HDAudio. And then, when you plug in front panel headphones,
it takes some control panel work to enable it. Analog Devices
chips have actual analog sensing - the chip sends a 25KHz AC
waveform to the jack, and can measure current flow into the
headphones - and then it knows headphones are there. For patent
reasons, RealTek doesn't have that.

Your best test case with HDAudio, is to test with the green jack
on the back of the computer, after verifying (in the case of
computers with *two* sound chips), that the correct sound
chip is selected as the default in the Windows settings.
I think you've done all this, so why this isn't working
is a bit of a puzzle.

While you can disable audio in the BIOS, I doubt that's
it either, as the item would then have disappeared from
Device Manager too.

To rule out a hardware issue, you could always temporarily
boot another OS and verify the sound works. That's if you
thought the 5V regulator feeding the HDAudio chip was blown,
or the outputs on the chip were blown. When both channels
disappear (Left and Right), that generally suggests a
driver or software problem of some sort. And muting the
speakers is a common reason for no sound to be present - again,
I'm sure you'd notice the indicator in the panel if that
happened :-)

Good luck,
Paul

I wonder
Do I or don't I have 'hi definition' audio? What is that anyway?
'bout time I found out I think.
Dumb Q I know/

Sam
What does it say in Device Manager?

Realtek High Definition Audio
The device is working properly
Thank you
Sam

So that leaves a damaged LineOut, some
kind of incorrect assignment on the channels,
maybe you're plugged into the wrong jack
out of the set of jacks ?

If it says RealTek, you can go to the RealTek
website and get their HDAudio driver. When you
install that, there will be a RealTek control panel
to play with. After a new driver is loaded, re-check
the Windows controls too (default Playback setting).

Non HP sites recognize the HP number. Use Google.

Well - the only audio driver I found there was for


Realtek High Definition Audio

Driver Date 2013-03-29 File Size: 146.88M
Driver Version: 6.0.1.6873 Vendor: Realtek
Supported OS: Windows 10 32 & 64bit, Windows 8.1 32 & 64bit, Windows
7 32 & 64bit, Windows Vista 32 & 64bit


Realtek_HD_Audio_Win7_Win8_R271

which I downloaded and installed, but it did not help.

I am not sure I have high definition audio anyway, since I am
connecting to the simple mobo audio port.

What do you think?

Thanks

Sam

RealTec seems to call most of their drivers HiDef.
What does it say in Device Manager for Sound?

I know many people have second thoughts about using 3rd party driver
programs but I have had extremely good luck using the free version of
Driver Booster 4 from Iobit. www.iobit.com/en/db/

I get
'page not found'
??
Sam

Let it have a try to see what it can find for a working driver. You
have the option of not installing the driver they find for your box.
Sorry looks like I grabbed the wrong link.
This one should get you to Driver Booster 4.
http://www.iobit.com/en/index.php

I cuda shuda Googled IOBIT to find the site, but I was tired.

When I tried your URL, I got:

Your connection is not private
Attackers might be trying to steal your information from www.iobit.com
(for example, passwords, messages, or credit cards).

I quit immediately!

Thanks anyway.

Sam

Since I do not have much installed yet on the machine, I ran Driver
Booster 4 anyway. It found a few drivers that it said needed
updating, but that the High Definition Audio is fine. And so, back to
the question - why no audio? Just maybe the audio part of the mobo is
bad? Altho if that were true I think Device Manager would not show a
working driver?
Oh boy!
Sam

You know - I thot of that, I know I did - to no avail.
But I just tried that again, and now I have sound out of a different
'jack out'. Go figger.

My guess is that when I deleted the original Realtek hi def driver and
installed the new one (which looked to be the same), the problem was
corrected. I shud have re-checked the jacks.
Anyway thanks for helps - it hurts to eat crow.
I apologize for wasting ur times.
