Stuttering sound with noisy clicks

[theRhino]

Im having the exact same problems as Serria has described in an earlyer mail.

Thumping, stuttering sound with random clicking and cracking noise.

My setup:
Motherboard ASUS P4B533 (Intel 845E Very common)
P4 2.4 GHz
1 Gb DDR ram
Raid with 2 120Gb stribed disks
OS Win2K

Im being told that this might be a problem with my chipset (=problem with VT).
Im spending all my time screwing around with my bios settup to get this working.
It took me a day to figure out that a frame buffer overrun was caused by plug&play being enabled in my bios.

Now i have spend 2 days trying to get the sound working.
Im already running out of time.

Newtek:

If my observations are caused by a wrong hardware settup. I would recommend a rewrite of your hardware requirments.
You need to explicitly tell US what chipset works and what doesent. I dont have time to "play" with my bios setup.
I have to go live in 5 days.
Before that i need to test the system.

Now with a different Motherboard:


Motherboard ASUS P4G8X (Intel E7205)
P4 2.4 GHz
1 Gb DDR ram
Raid with 2 120Gb stribed disks
OS Win2K

Result:

Slower stuttering.

NEWTEK:

At the same time i spend on trying different hardware (which is not free) with the Video Toaster.
Your product becommes less and less atractive.

The 7205 is a chipset that is known to work fine with Video Toaster, Rhino. The problem is likely elswhere.

The sound problem stopped when i removed my Adaptec 2400A controller.

Now im just using to disk. One as system disk and one as video disk.
Im thinking about using the onboard controller instead.
Does anybody have experince using the onboard controller on the
Asus P4G8X board?

Customers are having great success with the 3Ware Escalade (http://www.3ware.com/products/parallel_ata.asp) controller.

I made a new raid with two segate serial ATA disks

Result:

Same as before,
click crack pop.. stutter!!

BTW:

I tried with a new board from my retailer today.
Same problem occured.

[inquisitive]

hmm in my case i hear the crackle pop noises .. even if the vt toaster software is not running.. but it is not loud.. its low volume. and not continuous.

I guess if i didnt have headphones i would probably not hear it. unless it was amplified.

As soon as i logon hell brakes lose.
I can play any audio at all. It sounds like machinegun fire.

Have you tried an external fan pointed directly on the board? Other folks have reported heat related issues.....:(

[theRhino]

I was just about to do something like that.
Im a bit dumbfounded that i need to cool the card.
The temperature inside the chassis is pretty cold

Any way. Thanks for the tip. I will give it a try

[theRhino]

Placing a heatsink on the VT main processor did help.
But only for about 15 minutes.

I guess the VT is extremely sensitive to heat.
The chassy feels like room temperature when i touch it.

[Jim Capillo]

Try a fan and see if that helps. There are other chips that may be heating up causing your problems, not just the main processor. My box has more than 6 fans.

Do you have the card mounted near anything that throws off heat? If the heatsink fixed your problems, even for 15 minutes, you may be narrowing it down......

Good Luck!

[theRhino]

I have added thermo paste to the heat sink that is placed on the VT card and added an extra fan to the box.

It has now been playing for almost 2 hours without the noise and stuttering.

>My box has more than 6 fans
Thats a lot :)

Im pretty confident that this is a heat issue.

Tomorrow i will replace the chassy fan with one of those we use on our Intel servers (small jet engine) and also put a fan on the heat sink.

I am a brand new user here... not too much experience with VT2 but I did have this same exact problem and had to find a solution. The root of the problem for me was a bad audio cord... I was using 1/8" out to XLR into my DVCPRO deck... the cord was bad...

...also had loopthrough problems with the deck... was using the deck as player and recorder with the in/out of the toaster going through the deck. Once I replaced the cord and eliminated the loop through I was good.

One last thing... I'm having an extreme conflict with norton Anti-Virus software. I have a similar audio problem if I don't disable the norton before launching VT. With norton's running under the VT the same type crunch audio problem manifests itself 10-15 minutes into editing...

Hope this helps...

I tried a lot of tings too.
And most of the times it seemed to work.
What i forgot was that every time i stop the PC and made som adjustments the PC cooled down.
Then after some minutes after startup the problem would reorccur when it heated up again.

Now after i added an extra fan plus some termopaste, it works continuously.

Since my department is full of hardware engineers, we started stress testing the board and found out that it is very sensitive to heat. At about 60 deg. C. and above the card started get problems with the sound.
60 deg. C. is a relatively low temperature, that normally shouldnt cause any problems.

How many fans does you pc have?
Does it have an internal raid?

[Army dude]

I'm working with an IBM M-Pro Intellistation 6850-21U running dual 1.6g zeons. The chassy has only one fan... though it is large. My RAID is external....

I saw alot of talk of this issue previously when researching my problem.

My dealer looked at the PC and mentioned the same temp problems... especially with the dual zeons... but so far I've not been able to attribute the audio problem to heat. Basically, at this point, if I remember to disengage Norton before I start editing I'm good...
