I have noticed strange noises/sounds in my CW-system. I have never noticed that before. As soon as I start my computer I can hear all access to harddrive and keypress:es in my monitor. I have even removed all ide-cables and all other PCI-cards, just having Graphic AGP and my Pulsar2 and still the same problem, but less I think.
I have even tried to move my Pulsar2 to other PCI-slot but with the same result.
I think something is burned on my Pulsar2-card, as I remember right now I've got a feedback loop this weekend, feeding the analog input and round, feeeedback!
Does anyone have the same problem? Or is it just me? Maybe I have hade all time but never noticed that before, or...?
Shall I try to move the in/output-board to my SRB-card and try? If it is the in/output-board which is broken it doesn't help anyway.
No new computer HW has been added, just rebuilt my computer in a new case. I think it does not have anything to do with this because the strange noises appears directly after turning the comp ON, even during bios-boot sequence.
Strange noises
Hi, I'm not enought expert/technician to give you an aswer, but you can do a little test to understand where the problem is located:
Make a project with only a wave source and wave dest connected togheter. Then play something (eg an mp3 on winamp) and record it using your favourite program. If the noises will be recorded, then the problem is "inside" the board and maybe you have to move it to another slot or you have to ask for CW support (for example). It could be a software error i belive; maybe related to the OS.
Else, if the noises will not be recorded, maybe is the final stage.
To understan if this is true, drag in the project window and connect the analog out to the wave source and hear the mp3. If you hear that noises maybe the problem is hardware.
If you don't hear any noises yet, maybe the problem is located in the inputs, so disconnect wave source and connect the analog input to the wave or audio dest and record or hear something you play to the device connected to the in. If the noises appears now, then you know they are in the analog inputs.
You writed you have changed the case, maybe you have put the board too near the video card. Check this and try to put the board in the pci slot more distant.
Hope it heps

Yupp, changed computer-case but placed the HW in the same positions as before. Graphic at AGP slot and P2 at the last PCI-slot (tried both 4 and 5). I have Abit IS7.
I don't think there's some OS or SFP-problem because I hear the strange noises directly when I start my computer even before win or SFP-drivers are loaded.
I have also disconnect all midi/spdif/analog in and so on, only analog out to my mixer to be sure that it is not any ground problem, but it does not sounds lika a ground problem, more like buzz/fuzz and I can even hear when I press a key on the keyboard...
Also disconnected all HD/USB things.
The only connected ones are:
- AGP graphics
- Pulsar2 with only analog out
- keyboard and mouse
- powercord to the computer
It's nearly that I hope that the motherboard is broken, it cheaper than a new Pulsar.
I will try to:
- remove graphic card also
- put the P2 in other computer
SAAAAD

This is hard to describe but I will try:
1. I had it all installed on one computer
2. bought a new case, all other is same, even the PSU.
3. the case went broke (glass-window)
4. I lift things back out into the old case because I had to sent the whole case back.
And now suddenly I have that problem...I also got the nasty feedback this weekend.
I also used antistatical-wrest when I built the system.
DOH!

it IS a ground problem (imho), though different from the usual 2-or-more-cases setup.
your Pulsar picks up noise from the PC, a P4 system emits significantly(!) more than a P3 or alikes.
I have 2 boxes under my desk: a P3 dual with the Pulsar and a P4 for programming.
both share keyboard, mouse and screen with a KVM switch.
As soon as I switch to the P4 (but leave SFP on the other machine running idle, there is a specific noise (noticeable) at high volumes.
the same noise was present when the card was right in the P4.
possibly your cable whip has bad ground contact at the back of the case, or something else in the PC - that's 10 times more likely than a broken card, heads up
cheers, Tom

I have now tried the following.
- disconnect all things in my PC, even removed AGP graphic card, keyboard and mouse
- moved P2 to my Abit BH6 P3 machine, with the same result (maybe a little lower though) It is not a humming noise more like hearing the disk access.
- connected my P2 digital out to my NAD T753 Amp and it seems that if I use the digital out all buzz (strange noises) is gone. Still on analog out though.
Wierd, or...?

not exactly - the analog circuitry of the Pulsar is catching the electrical noise from the environment.
you probably mean a replacement of the analog connection by a digital one, but if the noise drops whenever you connect (addionally) it digitally then it's because the latter connection provides a usable ground.
those cable whips have been reported a few times to break inside recently, have you checked that ?
cheers, Tom

So you mean that it could be the external cable assembly that has a ground problem?
It doesn't sounds like a ground problem, more like the card is catching all periphical noises and so on...
I tried to record it yesterday but nothing is recorded though (good!), but it seems that it is some kind of external problem, I will try to connect it differently this evening to catch the noise.
