Noise from my Delta 1010?

One Hit Wonder
I have a Delta 1010 that I've had for about 3 years. This last week all of a sudden when I turn on my computer, it has begun to make noise. Something like a low hum, but a bit more annoying than just a hum, and fairly loud. Almost like a loose ground connection or something.

The problem starts immediately when I turn on the computer, and then gets louder once it has fully booted into Windows. Then a few minutes later it starts to get softer and finally goes away completely. It stays away until I turn off the computer again.

I'm pretty sure it's the Delta. I have the outs going to a mixer, and with the mixer on and the speakers on, I don't get any noise. Only when I turn on the computer.

I tried moving the PCI slot the card is in, and no change.

Anyone run into this before? Is it a sign the card is starting to go bad? Any suggestions?

I am assuming that it goes away once the components have heated up a little. Does that make any sense?

Thanks
 
I have a dim memory that this is a power supply problem.
Have to admit I've never clapped eyes on a 1010 in the flesh. Does the rack get all its power from the pci card or does it have a direct supply?
 
FWIW, 3 years ago, I had a 1010. A similar prob came. I contact Midiman, and they told me that there were problems with a batch of produced 1010. So I sent them mine, only the breakout box, and they sent me a new one, witch was ok.

So I would email them and talk to them about the situation.

Maybe I'm wrong, because I dont exactely remember how/when/what kind of noise it was.

But hey...you can email and ask them anyway!
 
i bet its out 1-2 right?
there was a batch of 1010's that after time, the heat from the power supply would short out the 1-2 outputs... sometimes even mess up the 1-2inputs.. try out 3-4.. if you don't have the problem.. contact m-audio/midiman about getting a new breakout box
 
Actually I am running channels 1-8 out to the mixer, with 7/8 used as my main outs. However, this happens immediately upon turning on the computer, before Windows or any software is loaded. As I said, it gets louder once Windows is fully booted.

Couple of things I noticed.
- If I disconnect the power supply to the breakout box, the noise stops.

- If I disconnect the cable between the PCI card and the breakout box, the noise stops.

- If go into the Delta software mixer and choose any sample rate below 44.1, the noise stops. 44.1 and higher and the noise does NOT stop.

Guess I'll shoot off a message to M-Audio.
 
yep..

copy-paste all your posts in a email to Midiman :) ..and hope you'll get an awnser soon!
 
Hmm i would call them. Youll probably just get a email about checking your IRQs for conflicts.

Thanks for the help guys. I sent an e-mail to M-Audio this morning. If I don't hear back soon, I will call them.

Since the noise goes away after a few minutes, the system is usable, so that is a help.

BTW, scratch my commemt about changing the sample rate. I tried it again, and now it has no effect on the noise regardless of the sample rate. Wierd.

I also tried shutting down and rebooting while the system was warm, and I did not get the problem. So it definitely seems to be related to heat (or lack thereof) in some fashion.
 
UPDATE:

M-Aduio responded by saying it sounds like my computer's power supply. (Don't you hate the finger pointing? :) )

Anyway, I have a second sound card in the computer (integrated mother board type). It isn't currently in use (no speakers connected) and Windows points to the Delta as it's main sound card. Tonight I plan to connect some speakers and redirect Windows to use the second sound card as it's primary.

If M-Audio is correct, I should get a similar noise from that setup as well.

Any flaws in this plan? Any other suggestions on how to further narrow down the problem?
 
Hmm it doesnt sound very likely to me, but it could just be that its going out.

Have you added anything to the computer that has caused a power increase? Even though this wouldnt really make sense its still a good question.

If its the fact that theirs not enough power then it would probably be different with a different sound card, because that sound card wouldnt be using as much power. But if it does happen to the other soundcard then it is definately a computer problem.

But ive never heard of a power supply doing this when it is going out, normally just wont start the computer or it will just blow up.

Nothing's been added to the comp. lately (except a new software sampler).

I tried it with the integrated sound card last night, and it was dead silent. Was able to play sounds through it, but no rumble/hum noise. I only got that when the Delta 1010 was on.

I still feel it's the Delta 1010, and I also recall hearing some of the stories referred to earlier in this thread around the time I bought mine. However, never having any trouble with mine, I assume the issues had been fixed before my particular unit was built.

I guess the only way I will know for sure is to put the 1010 in another 'puter. Royal PIA if you ask me, cause that gonna mean also installing drivers for it, and also get ahold of cabling to allow me to go from the 1/4" outs on the Delta to 1/8" mini-plug on computer speakers.

Speaking of which, I guess I need to look at a way to remove my 20/20 BAS speakers from the mix. Although they do not emit any sound when turned on by themselves - only when the computer is turned on as well.
 
If anyone is interested in this ongoing saga...

I unplugged my Intenet computer and took it from my office down to my "studio" and installed the Delta 1010 in it. Then I replaced my DAW with it. The minute I hit the start button I got the same noise (and I hadn'e even installed the drivers yet).

Farted around with a little more, but needless to say the problem lies with the 1010. I'm waiting on further instructions from M-Audio.

Sure would be nice if Jim Y had it right at the start. Bum power supply. Figure that can't be tooooo expensive. :(
 
How long have you had it? Id expect it would still be under warranty but either way, it sounds like a factory default to me because they have had so many units go out like that.

You should pressure them into replacing it for free.

Thanks. We'll see what they have to say. It's about 3 years old. Unlikely that it's still under warranty, but still a little premature to be failing IMHO.
 
May sound stupid, but it'S not...

Do you have Wordclock in/out connectors in the back?
 
Didn't mean to scare you, but...

Hmmm... I still think it has something to do with power supply, Dachay. I mean, I know M-Audio produces such great card, but I think their PCI products were a little bit picky about power supply. Minor anomalies on the power supply will ever make the card unstable which further more becomes unusable :( I had my Delta-66 "fried out" this way back then. Sorry, not to scare you, mate...

Which power supply, James. The computer, or the the Delta 1010??

And why would the noise go away a few minutes after the system has been started (and stay away, until I power down and let the system cool back down)? And why would I see the same problem in two different computers? And why would it work OK for 3 years prior to this?

Doesn't make sense to me. I'm betting that either the power supply for the Delta is going bad, or the PCI card.

Kryogh - Not sure. I don't use a word clock, if that is what you are asking. As to whether there are connections or not, it is a standard Delta 1010. I think it has word clock capabilities, but I've never used them.
 
The wordclock thing

oh sorry, I just asked about the wordclock (I never used this too!!) to see if the problem may be what I mentioned.

The Delta 1010 I bought, the one witch fu*ked up and got a similar problem didn't have these wordclock in/out on the back. The one they sent me back had them.

So, maybe if it doesnt have it, it can be the same problem. Nothing to do with te fact you can use or not wordclock with a 1010, only the batch your 1010 come from.

Sorry if I'm not clear, I'm doing my best :)

Well, there *could* be electrical shock that affect the PCI card circuit. So, something is broken or damaged. Do you run voltage regulator on your A/C line in before computer ? Well, take it easy, but in my case, it was unstable voltage supply that messed my PC. If you're not sure about your A/C line stability in your home / area, then I suggest use one on every critical machine at home. Pull the PCI card out, and look for any anomalies on the card in detail (mark of burn, broken circuit, etc...). Hope everything is fine... *we* still need the card for the BPOM project, right ? :D
 
My 1010 did the EXACT same thing. It would start off humming and then get quiet after 10 or 15 minutes. It eventually started humming louder and never quit. I sent it back to M-Audio and they repaired it for free. The paperwork they sent back said they had to change some capacitors but they didn't say which ones.

From the time I mailed it until the time it was returned was about 5 weeks or so. They also gave me a new powersupply.

See Ya
