OK, I know this isn't a real PC group but generally the people here are

I was given a PC with an abit IP35 Pro MB with Realtek Audio which works
in every respect expect there isn't any sound from any output. I'm running
XP with SP3 and, yes, all the volume controls are all the way up, nothing
is muted, and the speakers work fine on the PC sitting right next to it.
I installed the latest audio drivers (though no others since everything
else works) from the abit Web site at:

http://tinyurl.com/9sqrfn

The only anomoly is an unrecognized device in Device Manager, but it
isn't under Sound Devices. Of course with Windoze, anything is possible!

Google turns up a number of problems that sound (no pun...) similar.

There is one about XP SP3 causing a problem with the UAA (Universal
Audio Architecture?) but that seems to not recognize the audio hardware
at all. Here, everything is working but nothing coming out.

My fall back position is to buy a $7 sound card on eBay.

Any info appreciated!!

Have you checked the bios settings for the front panel audio?


If you need the motherboard manual:

http://www.abit.com.tw/page/en/download/download_manual_detail.php?pFILE_TYPE=Manual&pMAIN _TYPE=Motherboard&pTITLE_ON_SCREEN=IP35+Pro&pSOCKE T_TYPE=LGA775

Richt click on one of the mirror sites and save the link. It took
several tries to get a clean copy, but I finally got it from their Aisa
mirror.

ip35-pro.zip is the file you will be saving. It contains ip35-pro.pdf

The BIOS has the audio enabled. I've tried both HD Audio and AC97.

Does it go "ding" from the spkr during bootup?

Go unto:
Control Panel - Sound and Audio - Audio
and make sure the speaker output is coming from the Realtek chip.

Duz the Microphone/Audio input work or is it also kaput? Use the

Check the CMOS setup and see if there's a setting for redirecting the
sound from the rear to the front panel. There seems to be some kind
of automagic sound output redirection, depending on which 3.5mm jack
has the spkr attached, on the Abit board.

Also, make sure the audio settings are for commodity 2 channel stereo,
not 7.1 "HD" audio, which the board supports.

There seems to be a pin header on the board that goes to front panel

That might be wrong. Most PC's belch some kind of beep or ding during
bootup before Windoze loads. Check the speaker wiring. Better yet,
try different jacks among the multitude of 3.5mm audio connectors the
pollute the rear panel. (See manual below).

Hopefully, you're using amplified speakers, not the HP style where the
amplifier is in the PC.

Ok, let's play with some diagnostics.
Start - run - dxdiag - Sound
This will run the DirectX diagnostics which include some noises from
the speaker. If there are any driver issues, DxDiag will complain.

Try diagnostics that do NOT require Windoze. I vaguely recall that
there were some built in diags in the BIOS, but my memory might be
faulty. Most of my Dell and IBM machines have them. Dive and and see
if there's anything useful in there.

There are a bunch of diagnostics available that boot from a floppy or
CD. Of course, they're all sitting in my palatial office and I'm at
home. Google isn't being very helpful. I'm finding a zillion CPU RAM
and HD testers, but nothing for sound. Maybe a Linux Live-CD. Well,
try this:
1. Grab:
http://802.11junk.com/jeffl/crud/fonebell.com (12K)
2. Boot from an DOS floppy.
3. Run fonebell.com: It's suppose to sound like a phone ringing.
Well, it does on a 4.77MHz XP, but sounds more like a sick buzzer on
my 3.2Ghz Core2Duo. All I want it to do is make noise from the sound
chip without Windoze. If it works, you might have a driver problem in
Windoze.

When I find something better (for free), I'll post it (after I fix a
pile of trashed Apple G3 yo-yo laptop power supplies for the local
skool).

You must be desperate. I never read the manual until after I fix the

There *may* be a fix regarding something that installing service pack3
did (or didn't do), or it could indeed be something broken on the chipset.

Even if you boot from a linux boot CD (or install windows 7) and find
the sound working with that, I'd spring for a cheapie $7 soundcard -
it's not worth spending time if other more $$$ things are being
displaced from your interest.

Check the MB jumpers around the audio chipset & audio I/O
sockets. Some motherboards use jumpers to switch audio between the
internal sockets, or external sockets. Try looking up the MB model
number on the manufacturers website, & hopefully you'll be able to
find a diagram showing where all the jumpers go, & what they're
for. You might even find a jumper than enable/disables the internal
sound chipset.

No jumpers that I could find even in the manual.

On board sound chip failure is very very common. I wish I had a £($)

card added because of it !

I've seen chips fitted rotated 90 out on the mainboard.

Some of it is unnessary circuit complication though which causes
headaches installing the right driver, as there are /two/ of those to
install with either AC'97 or (the later) High Definition schemes in use.

The first for the motherboard chipset HUB controller (normally Intel,
but AMD and Nvidia as well) and the second for the Codec (Realtek,
Conexant, and Analog Devices). Then ye get the headache of Microsoft
stepping in and wreaking the compatability of everything.

http://en.wikipedia.org/wiki/AC'97
http://en.wikipedia.org/wiki/Intel_H...finition_Audio


I've seen chips fitted rotated 90 out on the mainboard.


Laterally or tombstoned?

I've got a cheapie Gigabyte AMD board here I'm scrapping. The board had
so warped on the wave soldering machine, that the DDR sockets only grab
memory modules by the edge contacts and bows away from the middle.

Complete junk.

That unrecognized device is the sensor for uGuru. Download uGuru
utility from Abit site and it will give you all the information about
your mobo, i.e. fan, heat, voltage etc. But not sound.

Before you buy sound card, check your L/Speakers on you TV or any
other device if its has audio output socket such as Head Phone socket.

Hope this help.

The only anomoly is an unrecognized device in Device Manager, but it
isn't under Sound Devices. Of course with Windoze, anything is possible!

Google turns up a number of problems that sound (no pun...) similar.

There is one about XP SP3 causing a problem with the UAA (Universal
Audio Architecture?) but that seems to not recognize the audio hardware
at all. Here, everything is working but nothing coming out.

My fall back position is to buy a $7 sound card on eBay.

Any info appreciated!!

Buy PCi sound card.

Ok, that means you have a working sound chip, but no connection
between the chip and the speaker. I can't tell where it's broken from
here. If you can identify the Realtek sound chip, perhaps you can
find the data sheet and identify the sound output pin. Then, use a
scope to see if it's putting out any sound at the chip. If there's
sound at the chip, but not at the output connector, you have a
motherboard with a possible broken trace, blown audio amp (if
present), or broken coupling cazapitor.

Fonebell Sounds like a busy signal through the PC speaker.

Ooops. I forgot that it default to the timer sound output instead of
the sound output. I wrote that in 1985 and my memory is becoming
rather ummm.... dynamic.

And note that there was no PC speaker installed before. So, there is
a BIOS/POST beep now from the speaker as well.

Some motherboard run the PC speaker audio through the sound card.
Apparently, this one does not. So much for that idea.

But nothing from the speaker in Windoze.

I'll keep looking for some DOS based diagnostics with a sound test. It
may have to wait until I drag myself to my palatial office sometime
next week.

You might find something useful under this review:

This might be a diversion but could be causing the sound to be muted:
Viiv support (i.e. support for Quick Resume technology, which
allows the PC to imitate the behavior of TV sets, where by
pressing the power button located on the remote control the
screen goes dark, the sound is muted and the keyboard and
mouse stop responding)"

Bingo. It's a Realtek ALC888 sound chip. Digging...

Data sheet link is at the bottom of the page. Section 6.2 shows front
audio outputs on pins 35 and 36. Dust off the oscilloscope and see if
there's any sound on those pins.

On board sound chip failure is very very common. I wish I had a £($)
for every new machine or mainboard I've seen that had to have sound
card added because of it !

Some of it is unnessary circuit complication though which causes
headaches installing the right driver, as there are /two/ of those to
install with either AC'97 or (the later) High Definition schemes in
use.

The first for the motherboard chipset HUB controller (normally Intel,
but AMD and Nvidia as well) and the second for the Codec (Realtek,
Conexant, and Analog Devices). Then ye get the headache of Microsoft
stepping in and wreaking the compatability of everything.

http://en.wikipedia.org/wiki/AC'97
http://en.wikipedia.org/wiki/Intel_H...finition_Audio


I've seen chips fitted rotated 90 out on the mainboard.


Laterally or tombstoned?

Laterally rotated. Instead of having the reference at bottom left it was
at the top left. The pcb was correctly marked.

I've got a cheapie Gigabyte AMD board here I'm scrapping. The board
had so warped on the wave soldering machine, that the DDR sockets only
grab memory modules by the edge contacts and bows away from the
middle.

Complete junk.

Mmm. I've only seen that kind of thing on counterfeit boards. Which as
it happens is where I saw the sound chips rotated.

I know that logic dictates using the motherboard maker's website for

sometimes work when the OEM driver doesn't. It might be worth a try,

Downloaded uGuru, works fine, still unrecognized device. But that

Before you buy sound card, check your L/Speakers on you TV or any
other device if its has audio output socket such as Head Phone socket.

Speakers run fine on PC next to it.

Sure. If I'm doing motheboard repair, I need access to the bottom of

a plywood fixture for doing that.

two broken traces?

Good point. However, if there's a common audio power amplifier or a
broken sweat solder job on the output connector, it's possible to
break both at the same time.

Incidentally, did you ever try the sound INPUTS to see if the chip is
alive and well? Plug in a microphone and use the Windoze sound
recorder for testing.

Also, this is kinda dumb and obvious, but might be the problem. The
chip has multiple outputs which can be switched in software. Go unto:
control panel - sound and audio - advanced
or just double click the speaker icon in the system tray.
That should display a list of "playback devices". Make sure nothing
is muted, none of the controls are set to zero, and that all the
outputs are correctly enabled (not muted).

Thanks for all your efforts!

No ! the sound never worked. Counterfeit Chinese mainboards. A sound
card was added, plugged into a PCI slot to get around the issue. A
case of scrap them or use them. Minimise the loss !

Sure, there may be some shining examples I haven't come across. The fact
that your chipset is HD must mean they took some care on that one ;-)

As much as possible, if I'm using an onboard sound chipset I try and
find an S/PDIF output and use an outboard DAC connected to that. I find
some sources of music that ye get via broadband really benefits from
that. Nice, non-flabby and crisp ;-)
