noisy ASIO

nicked · Post by **nicked** » Thu Oct 04, 2001 1:31 am

my pulsar II works fine, except that asio source is very noisy. mid/high frequency jittery computer interference type noise. any ideas? perhaps a cubase 5 problem?

This is probaly due to a noisy fan. i had the same problem and solved it by buying a isolated fan

Is it since you upgraded to V3? I have noticed the ADAT IO is a little noisy after V3 upgrade.

TB

no i have always had this problem.

if it is a noisy fan, then why don't i get the noise from directsound? it is only asio. if asio source is not connected to analog dest, it's as quiet as a mouse.

ps the noise disappears when performing certain operations. suggests it can be got rid of. if it was interference from the fan i imagine the noise would be constant.

i posted about this problem a while back, but i didn't realise then it was only asio. i thought perhaps this new piece of information might help somebody figure it out.

creamware didn't have any answers either.

Do the following: In your sequencer prog. Ex. Cubase try to left click on the transport bar and move it around. Do the noise stop during this operation..?

not sure...i use the net at work, so i won't be able to tell you until monday whether this works. but you could be right. it is when clicking on certain things that the noise disappears.

I had this problem of noise and I solved it by switching from 44.1 to 48 khz. I don't know what causes the noise or why rasing the rate solved it. If anyone knows I would be interested to hear why.

1. i was wrong - it's not just asio - i musta been trippin. ? although i would swear it WAS just asio. maybe just that one time.

2. yes vince, the noise disappears when i drag the transport bar in cubase.

3. i will try upping the sample rate.

I have the same or equal problem with noise ( also not asio related )

my setup is:
asus p2b-vm ( onboard audio is jumped off )
pIII 500 mhz
320 mb ram
ati rage expert 2000 32mb
8.4 gb udma 5400 rpm
20 gb udma 7200 rpm
3com ethernet card
Usb disabled
Pulsar 1
pulsar 2 srb

I did all things suggested :
- Grounded hardware ( with out ground loop)
- I now have quatily cables on analog out ( that son't pick up interfirence )
- No cables are crossing each other
- no irq sharing ( both card on same irq)

Stil i have this =/- 800 hz tone and noise coming out.
It gets some kind of influence from my system, when hardisk is active or activation funtions in a software app. ( does not matter wich app. )

I also tryed the new sp/dif optical thru my mididisc and then to my amp and there was no noise at all. this means it is definately ad/da related. and for the reasons mentioned above it proves to my knowledge that the creamware hardware (ad/da)is picking up noise from insite the my computer.

This is the same in win98se with v2.04
as in win2000 with v3...
Same noise...!!!

The Creamware cards are sheilded they say so way is it pickup up this noise, could it mean that my card is broke and should be fixed or replaced by a new one ???
Cos this is intoleranble when i am monitoring my makings!!!

Thats all, Djody

buy the way i love the v3 update amazing improvements, hope the update wil solve all the little details....

it sounds like you are hearing exactly the same noise as me..

if you didn't hear it on a digital recording, then perhaps the noise comes only from the analog out.

if so then it will not be present in any recordings, and so is not really a major problem.

djody · Post by **djody** » Mon Oct 08, 2001 5:43 am

when i record internaly and write it to cd and check it on a my system downstaires there is no noise.

But i find it very annoiing while creating that i' constantly get hamered by the noise, espesialy while designing sound at high volume. Then i tweak and hit my keyboard and in between i hear the noise.
For a pro audio card this is not OK at all
i expect it to by noiseless.

An other point is that i can not use outboard hardware thru the analog outs cos then i get the noise in my mix!!! that's bad.

I think i tryed every suggested solusion. so if no one has a new thing to try i guess i have to be going thru the creamware support jungle to get rid of this Problem.

I,m goin to post this also at creamware forum, maybe ingo or somebody else from creamware can help me out on this one..

Cheers and good luck, Djody

I only use the sp/dif out for monitoring.

nicked · Post by **nicked** » Tue Oct 09, 2001 1:11 am

yep, the noise definitely disappears completely when you click and drag the transport bar in cubase. (!)

I have a strong guess that you have DirectX 8.something beta installed, right? That has issues with DirectDraw.

I use DirectX 7(latest final version), and do not have this problem.

Also update your video card BIOS, update your video card drivers, uninstall the version of directX you have, and use the latest version your video card mfg suggests/endorses.

where do i get direct-x 7 and how do i uninstall dx-8

Thanks

I now have a dual boot system. One OS for Music and another for graphics and games (including Directx

.

FWIW, i have my OS set up with no direct x whatsoever.

98lite micro on CUSL2 with GX450 video, PslrII, Luna, and Cubase, & misc utilities, goodies.

never had any problems due to lack of DirectX, but its a pure DAW box, with very few apps installed. nothing I use (at least for the moment) seems to have a problem with the lack of DXx.

I believe there are plenty of other hardware and software thingies around which do need it, so this may not be an option for everybody. My point is simply that depending on what you use its possible to live without DirectX and its attendant problems.

OK! The problem is 99% this: It is your grapichs card. Try deactivating bus mastering, preferably use a AGP card

actually i'm starting to suspect my old and very cheap scsi card.
