I use the spdif out from my recent ASUS motherboard to a Beresford
Caiman DAC and I get static pops something like every 30 seconds. I
use Windows XP, and I have a 25 feet coaxial cable to feed the Caiman.
It is ok when I use the spdif signal from my cd player, so I know the
problem is related to the computer.

Has anybody experienced this problem?

What makes you think it's a static issue and not a data overrun issue?

Is both the DAC and the motherboard set up with pulse transformers or are
they violating the S-PDIF specs by not ground isolating (like sadly most
cheap interfaces do)?

Is the clock input on the DAC set up correctly?

Right, I should have said that is *sounds* like a static issue.

I don't know. All I can say is that it's a ASUS P6T SE motherboard. It
runs with a i7 920 processor. If it's a ground isolation problem, is
it something that can be solved easily?

As far as I know, there is no setting for the clock on the DAC.

Look at the interface and see if you see a transformer there.

If it's a ground isolation problem it may or may not be a big deal. Do you
hear it even with just a headphone plugged into the DAC output and the DAC
floated from system ground?

Is the clock input on the DAC set up correctly?

As far as I know, there is no setting for the clock on the DAC.

If it has no other clock inputs, then it always gets clock from the
S-PDIF in and so you have that much less to worry about.

Windows. I tried with Reaper, Winamp, Foobar2000 and it does not seem
to make a difference.

I will check that. Thanks for your help!

Okay... WHICH windows? And what drivers for the interface? And are you
using the video card on the motherboard or an external video card?

So what happens on your computer every 30 seconds or so?

Your problem is probably not static.

Your problem is that something is interrupting the flow of data to your DAC
every now and then.

Too much software? On the web or other network? Not enough RAM? Bus
contention?

use Windows XP, and I have a 25 feet coaxial cable to feed the Caiman.

So far so good.

It is ok when I use the spdif signal from my cd player, so I know the

Probably.

Has anybody experienced this problem?

In one context or another.

Simplify, simplify!

[Martin Chicoine]

Ok, I will try to summarize all relevant details.

The DAC is a Beresford Caiman (http://www.homehifi.co.uk/products/
Caiman.html). I don't think it is the culprit because it runs just
fine when I use it as an external DAC for my cd player.

The processor is a Intel i7 920, which is a quad-core. It has 4 GB of
RAM. My OS is Windows XP, and it has the most recent updates.

The motherboard is a Asus P6T SE. It has onboard SPDIF I/O. The audio
chip is a Realtek ALC1200. I installed the latest driver, which is
from late 2009. The video card is a NVidia PCI-E external card (I
don't remember the model).

I tried mp3, FLAC, and WAV files played through Winamp, Foobar2000,
and Reaper. I tried to play the files through Kernel Streaming, ASIO,
and Direct Sound output plugins. No matter what, I always hear clicks
(which sound like static clicks) something like every 30 seconds. I am
not touching the computer at the same time and no other program is
running.

So I suppose the problem is either Windows XP, which for some reason
may not work that well with my hardware, or either the onboard audio
chip.

Thanks for your kind help!

Martin.

The statement "no other program is running" was probably not made with
reference to the Windows Task Manager. Particularly check the "Processes"
tab.

Also, take a look at the startup tab of Msconfig. To run Msconfig, click
Start, run, and type Msconfig, and press the IK button.

So I suppose the problem is either Windows XP, which for some reason
may not work that well with my hardware, or either the onboard audio
chip.

Unlikely.

But, also check to see if there aren't updated drivers for your audio
interface, and the rest of the computer as far as that goes.

Just a first cut, but try to click Start, Control Panel, Display, Settings,
Advanced, Troubleshoot, and unclick "Enable Write Combining" and also move
the "Hardware Acessleration" slider fully to the left. Click OK and agree
with everything as you back out of the menus.

Martin, it is the DAC. The DAC is not defective, but it cannot handle the
clock instability of the Asus motherboard. I offer these observations
having dealt with the specific problem.

Good point.

I might have been skeptical about this possibility had I not read of similar
problems related to audio interfaces with ADAT ports.

Do you know this specific DAC? If you are right, I can change either
the DAC or the motherboard. What do you suggest?

Under socialism it's all high fidelity by definition. All
audio is done according to plan, and is therefore correct.

** Update **

Strangely, after doing some tests, the problem disapeared. The only
reason I can find to explain this is that I displaced the cable. It
was passing near some AC wires. Is it possible that the 25 feet
coaxial cable is not well shielded, so that there is some static
accumulation or something like that?

That's unlikely but you might not have had a good connection on both
ends. That will cause crackling noises in digital connections as well as
analog.

Too bad. Bose stuff is overpriced junk. I went to a Bose demonstration once
where the demonstrator was playing a huge pair of floor-standing speakers. He
was telling everyone how great they sounded. All I heard was lots of
distortion. Then, after pumping these huge speakers as the best thing since
sliced bread, he took the grills off the speakers revealing that they weren't
speakers at all, just frames around some small stands holding a pair of those
tiny Bose cubes. They were still distorted. I have a friend who has a "Wave
Radio" in her kitchen. The "amazing bass" is boomy and mostly one note, and
above a whisper, it too is distorted.

Bose is a prime example of success through hype, obfuscation by advertising,
snob appeal by high price. No thanks.
