no sound - problem with motherboard

[MarcinR]

Hello

I have problem: there is no sound from my SB Audigy 2 Value.

Here I describe how it happened.
I was trying to install a new cooler on my Sapphire Radeon 9600 XT
(Pentagram Freezone XC-70 Al+). It wasn't easy, because it doesn't fit
exactly to my hardware (but the manual of that cooler says it does...
:|). (Maybe it's because my motherboard. The problem is that the
radiator touches the PCI bus, that is near AGP and Radeon can't be
inserted properly).

Ok, I've tried several times to insert Radeon in AGP slot, and finally I
took off that cooler and installed another one. Then I've spotted that
there is no sound, even noise in speakers when they are turned on. It
can't be a software problem because there is no sound under Windows XP
and Linux both since the same time.

Speakers work, I've checked on the other source. Sound card works, I've
checked it in another PC. PCI works because network card is working all
the time.

The question is: could I destroy something on the motherboard, that
doesn't interrupt network card's work, but make that problems with PCI
sound?
I've also tried to install my AC'97 sound card integrated with
motherboard but it seems to doesn't work too.

And at last, a small tip: there is a small cut (0.5 mm x 2 mm) on the
motherboard near the PCI bus, nearest the AGP. Probably I've made it
with screwdriver when I was trying to install that cooler
Can it be the source of the problem?

Sorry for my bad english :]

The question is: could I destroy something on the motherboard, that

sound?

No, unless it was something only loosely related such as
damanging the PCI slot it's in, or gouging the motherboard's
trace(s) to the slot, or bending or otherwise physically
stressing the sound card itself but that seems not the case
from what you write above, and below.

I've also tried to install my AC'97 sound card integrated with
motherboard but it seems to doesn't work too.

Had it ever worked? Does the OS, particularly windows, show
it as a viable sound device in Multimedia section of control
panel?

AC97 sound on your board is not going through the PCI bus,
it's southbridge integral then a serial line to the codec
chip on the left hand edge of the board. Damage to a PCI
trace should not interfere with this too. It might be a
silly question but are you sure you have the right audio
output jack, right driver(s) installed, and the motherboard
FPAudio header jumpers installed on the correct pins
(assuming you're taking the audio from the jacks on the rear
of the board, which I suggest doing, not trying to use a
case front panel audio output just yet to rule out this
variable).

And at last, a small tip: there is a small cut (0.5 mm x 2 mm) on the
motherboard near the PCI bus, nearest the AGP.

It is just a surface blemish in the PCB or does it look like
you've severed a surface trace?

Probably I've made it
with screwdriver when I was trying to install that cooler
Can it be the source of the problem?

It's certainly possible, but insufficient information to
know. You could try posting a very very high resolution
picture of the area and linking it here, or if you have
experience using a multimeter, attach needle tipped probes
to it and either trace back this trace to termination at
both ends and check the continuity, or find convenient spots
to pierce the coating and make direct electrical contact to
the trace with the needle probes, very very carefully, with
motherboard pulled out on a table, strong light, etc. Don't
push too hard else you may damage it doing the test, a
needle can easily reach the first copper layer.

If all else fails, clean the CMOS.

Hmm, in that case only one slot could be damaged. The sound card doesn't
work in any slot.

Yes, it was working long time ago, I just don't use it since I bought
Audigy. The problem is that I don't remember how it was configured
(although it must be quite simply and now I don't know if the problem
with configuring it is about that troubles with motherboard or something
else :]

Yea, i know it

Damage to a PCI trace should not interfere with this too.

If it's really PCI damaged...

It might be a silly question but are you sure you have the right
audio output jack, right driver(s) installed, and the motherboard
FPAudio header jumpers installed on the correct pins (assuming you're
taking the audio from the jacks on the rear of the board, which I
suggest doing, not trying to use a case front panel audio output just
yet to rule out this variable).

Hardware configuration wasn't changed since I've last used the
integrated sound card (if I accidentally don't move any jumper during
last time, but it doesn't seem to). It can be a software problem, but it
can concern only that card, the Audigy worked until that "accident"
happened. But ok, I'll check it.

It is just a surface blemish in the PCB or does it look like you've
severed a surface trace?

I'm afraid that the second one :| Something white is visible in that place.

It's certainly possible, but insufficient information to know. You
could try posting a very very high resolution picture of the area and
linking it here, or if you have experience using a multimeter,
attach needle tipped probes to it and either trace back this trace to

push too hard else you may damage it doing the test, a needle can
easily reach the first copper layer.

I don't have the camera that could made so high resolution pictures.

If all else fails, clean the CMOS.

You mean reset to defaults in BIOS or reset using jumper on motherboard ?

The jumper, while system is unplugged from AC.

Hmm, my mistake. The integrated sound card was disabled in BIOS. After
enabling it, it was detected and installed properly in Windows and Linux.
But effect is the same as with Audigy - absolutely no warnings or errors
form software, absolutely no sound from speakers :/
