Sound Card Problem

For some reason, the onboard sound card in my IBM 6579 computer (Intel
motherboard) clips the audio input at -5db. There's nothing I can do to
drive the input signal to 100%, although it is 100% clipped at -5db. I
installed the latest driver, but that did not make any difference.

The problem is not in the application, because it shows the same
behavior with FastEdit, CoolEdit, and TotalRecorder. When the input
audio is being monitored, it is clean. When I monitor the input with one
of the applications above, the flatlining at -5db is plainly visible.

The system is Windows XP Pro SP2. I have two other identical systems
that do not show the problem. The problem could obviously be a bad sound
card, but I thought I would ask before trashing it. Does anyone have a
suggestion for where to look? I have checked every input level setting
that I can find in Mixer, in the applications, and directly on the driver.

This sounds like an issue with the sound card, or something is not
calibrated properly. Personally I would get a really good sound card,
disable the one on the mother board, and install the good one. I like the
higher end of the SoundBlaster cards. The Turtle
http://www.turtlebeach.com/site/ is also supposed to be very good.

Any of these sound cards will be superior and offer a lot more options than
the built in one on your mother board.

Good call.

On the circuit card.

According to:
http://developer.novell.com/yes/62602.htm

This is a Intel 815E chipset-based system.

According to

http://www.intel.com/design/chipsets/815E/

The AC97 audio function is integrated into the chipset.

According to

ftp://download.intel.com/design/chipsets/designex/27363...

page 52 (of the pdf) there is a separate AC97 chip. It has probably
become damaged or defective.

The big clue was the fact that 2 other identical systems lack this
fault.

Have you checked the Recording Volmume setting in the Windows mixer
applet? If that's low, you could be clipping the analog stage before
you reach full scale record level. It's hidden under the
Properties/Options menu when you click on the loudspeaker icon.

Sounds like a bad card to me. I'd chuck it.

I can't imagine why you'd need to record right up to 100%, but that's
another issue entirely.
