There is no audio from the speakers, but they will work if plugged
into the earphone jack. The system says that the speakers are not
plugged in. The computer is an HP, the sound is Realtec. Just cannot
enable speakers in Playback window.

plugged in. The computer is an HP, the sound is Realtec. Just cannot
enable speakers in Playback window.
The first thing I'd do is find out what Realtek sound chip is used.
Then, assuming a "standard" audio system, check for and download/install
updated audio drivers. Finally, since this is an OEM machine, HP may
have used an HP audio control module instead of the Realtek module.

I've had the no detect problem in the past. It turned out to be BIOS and
case configuration, in that the case audio wiring had two plugs
that either/or plugged into the MBD. Both the BIOS and the plugs needed
to agree as to which "standard" was activated.

At one time, on some systems, one bit in a registry entry would bi-pass
the no detect issue. Since that was several years, models, and audio
chip sets back, I have no idea if it still works, or even what the
current entry might be.

Hi Paul,
The model No. is P6774Y

OK, product page.

http://h10025.www1.hp.com/ewfrf/wc/...foCategory&lc=en&dlc=en&cc=us&product=5049534

Drivers page. Select 32 bit or 64 bit, depending on which is installed.
It's probably 64 bit, even if 64 bit isn't really needed as an OS choice.
(That's what my laptop came with.)

http://h10025.www1.hp.com/ewfrf/wc/...dlc=en&docname=bph07165&lc=en&product=5049534

This is their RealTek sound driver. 75MB covers just about every chip RealTek makes.
You can also get such a driver package from RealTek themselves, but sometimes,
HP pays extra for some Dolby software feature, in which case, try the
HP driver first. For any of my motherboards with RealTek, I'd just get the
driver from RealTek, because the motherboards hardly ever have special features.

http://h10025.www1.hp.com/ewfrf/wc/...dlc=en&lc=en&os=4063&product=5049534&sw_lang=

The product spec says the sound is "Audio CODEC: ALC888S-VD 8 channel".

The thing is, if you are getting sound from an earphone jack, then
lots of stuff must be working. That means you must have a working
HDAudio driver from Microsoft, as well as the sound driver for the
chip.

Have you checked the volume sliders in the control panel ?

Are any of the "mute" buttons clicked ?

Realtek also has a control panel with images of the jacks in it.

In looking for a picture of the control panel, I found this thread.
You can experiment with the front panel jack detection thingy.
Maybe your problem is related to jack detection.

The thing is, my laptop has Windows 7 and it has RealTek Audio,
but it only has two channels of output and many of the features
in the control panel are greyed out. So I can't even do any
decent experiments - my hardware is "neutered" :)

Hi Paul,
It turned out that the Stereo Mix was not enabled in recording
devices. That fixed it. Thanks for all of your effort.
