On Board Audio Output Noise...

After reading several posts, and making adjustments throughout Win2K, I have yet to get rid of the continual static noise which fluctuates in intensity depending on hard drive and general system activity.
I have no IRQ or resource conflicts to do with the sound card. I have the reproduction properties set to Full and Best.
Could the on board sound hardware be defective?
I haven't tried swapping in a PCI-style sound card to see if the problem goes away.
Any other ideas appreciated.

If you are using a cable from the cd player for audo, enable digital input instead.

890GXM-G65 on-board Audio white noise when shutting down ... Please Help

Just got this board on ebay. Runs great but when rebooting the following happens:
MSI 890GXM-G65 on-board Audio produces a second's worth of white noise (radio no-station-tuned static sound) when shutting down - about a second before the screen goes bank and the PC restarts
I don't mind the noise but is this normal or should I send the board back ?

I'm using the following hardware :
Athlon II x 3 440 AM3 (unlocked 4 cores @ 3.6GHz)
Thermaltake MaxOrb
MSI 890GXM-G65
2 x 2GB Kingston 1066 CAS 7 DDR3 KVR1066D3N7K2/4G
MSI N460GTX Cyclone 1GD5/OC
OCZ Fatal1ty 550W Modular (Dual Rails +12V@25A per rail)
WD 250GB 7200rpm SATA II
Thermaltake Gaming Cube VF6000BNS
Windows 7 x64 Home Premium
19" Sony Triniton CRT Monitor
All Windows Sounds are turned off except for Device Connect / Disconnect / Connect Failure. I have an Audigy 2 PCI card but I haven't tried it because the drivers always lock up the PC when I run MSI Afterbutner, eVGA Precision or almost any other hardware monitoring utility.
Since I flashed the BIOS to v1.B I feel I can't return it to the seller but I really like the board and it works well, except for this integrated audio issue. I won't return this board - it's a keeper.
Still, I'm hoping for a fix if possible.

Extreme audio output noise

This new MBP is extremely noisy in the external speakers. The noise I would call "Processor hash", with lots of squeals, chirps and hisses depending on what the computer is thinking about. Is this normal?
I do not hear the noise from the little built-in speakers. The noise is so intolerable I must turn off my sound system while not listening. It is impossible to listen to quiet ambient music. The noise stops while the computer is sleeping. Also, the noise is not responsive to volume settings. It is the same regardless of the volume from the computer.

This is a problem with all current Macbook Pros, as far as I know. It bothers some people, and not so much others.
A topic discussing the issue (mostly while using headphones) is here: http://discussions.apple.com/thread.jspa?messageID=5687014&#5687014
The quick answer is that higher impedance headphones or speakers can help, and Radio Shack sells a cheap little thingy that should fix the noise problem.
Hope that helps!

Help!! No AUDIO output from iMac through FW to mixing board (zed r16)

With my system stated below, I run an Allen-Heath ZED R16 board via FW. PROBLEM: I get NO Audio output to the R16 when I play iTunes or DVD/CDs in the iMac.
I DO get audio feed when I playback projects from Logic.
I have checked all System Prefs on the iMac (cahnged to the ZED); on Logic (changed to the ZED). I tried all different channels, routing, etc. NOTHING.
Can someone help?

Well, the Allen-Heath support site had the answer... quite surprised and pleased!!
Have to reconfigure the iMac speakers in the Audio/Midi preferences. The details are found in this URL:

The ZED R16 is a great board but certainly not Plug' n Play.

I recently downloaded the latest OS update and now I have a constant "humming" noise from my MBP and my audio output is no longer working. Any suggestions?

I recently downloaded the lastest OS update (Lion X 10.7.4) on my MBP that I purchased in November of 2011, and since downloading it my MBP has been making a constant "humming" noise from the right speaker/disc drive area. I also don't have any audio output for FaceTime or Skype. I attempted to use Photo Booth to record a video and it doesn't record any audio. I attempted to reset SMC and reinstall Lion with no resolution of the problems.

Click the Finder icon on the Dock.
Applications > Utilities > Audio MIDI Setup
Built-in-Output
Output tab
Move the Master volume slider to the right a bit.
Best.

Noise on audio output when using the power adapter

I'm a musician and use my mid-2007 MBP 15" in my live rig. When I use the power adapter, I hear a buzz, sometimes accompanied by a slightly louder buzz that cycles on & off about 1x/second. There are a few weird things going on here:
1. The buzz does not happen all the time. That leads me to think it may be noise in the AC line that the adapter is plugged into.
2. The noise is heard when I use both the built-in audio output AND an external USB audio interface.
In any case, when I disconnect the power adapter and run my MBP on battery, the noise goes away completely. I can probably do this on most gigs, but I'm a little nervous since I run a FW drive, an external USB audio interface, and my midi keyboard (powered by USB) so I am putting a little heavier than usual load on the MBP's battery.
As I said, this may be a noisy AC line. Another guess is that it's the PMU inducing noise into the audio circuitry. I'm hoping a simple AC line filter can help me but I thought I would ask here first in case anyone else has dealt with this. TIA for any help!

I had a similar problem and fixed it with a $5 universal travel adapter. Yours might be different but here's my situation. Try it for little cost and see if it works.
I'm also a muso with an iMac running external KRK speakers via USB Mbox2. Previously I had a Macbook Pro and the same audio problem. I've been putting up with a very low volume, high pitch noise until now. I simply plugged the Mac power cord into a universal travel adapter which then goes into the wall. For Aussie users there is an adapter on ebay that will allow a 3 pin Aussie plug to go into female side and has a two pin Aussie male on the other. For US users you can probably get the same although there is a 59c product that will do the trick called a ground lift adapter. Applecare actually agreed this was the best fix and confirmed there would be no problems with power supply or Mac performance. What a gem ! God knows I've looked into all kinds of alternatives that could have cost hundreds instead of $5.

Firewire drive noise appearing in audio output

Hi:
When I have a firewire drive plugged in, a lot of digital noise appears at the audio output jack. If I turn the drive off, I hear a whining-down noise in the audio output. I've tried two different drives, 3 different cables, same thing. Anyone have any ideas? It's a huge bummer; I bought my MacBook Pro to do music on...

Hey george,
i know this is not going to be any help, (i need some too!!!) but i have exactly the same problem. I first noticed it when using my ICY BOX external harddrive and thought it was just the noise from the external drive but the same thing happens when i attach my Motu traveler firewire soundcard to it. Its so annoying. the sound dissapears when i take out the mini jack from the output.
I am also having a problem of sound distortion over the output and recording input when i attach my Motu firewire unit
(this is seperate from the minijack problem i think as this happens when the minijack is plugged into the output AND when it is not).
This didnt happen to my powerbook 1.6 and never happens to my friends one either????
I am going to make a seperate thread about this problem now but if you could tell me if you have the same problem with your soundcard i would be grateful.
All the best and if you find out what the problem is please post your solutio up, vice versa.
Will.

Processor noise with audio output?

I attached my Mac book pro to my 40" LCD TV along with an audio output from the headphones out to the input on the TV.
What I noticed is that the "processor whine" that we all complain about that seems to cease when we are running things like photo booth, and intensify when we disconnect the AC adapter, is projected through the audio of my TV!!!!! When I mute the TV, away goes the whine. Strange huh?
I don't know if this is a new revelation, or a known reproduction of the problem.
So my question is, do you think there is a relationship between the poor output on the speakers (very little sound on bars 1 through 7) and this processor whine we complain about?
I was generally happy with my MBP and would ignore the whine until my TV set amplified it.
Do any of you also think that Apple would replace my MBP for this and the many other complaints? (Screen inverter defect, generally hot, and this noise output via cable)
Thanks for your input on my future with this computer, like I said, I've always been happy with it until this output problem.

My guess as to what causes the whine is this:
There are many small copper traces on the motherboard carrying signals. There are two traces in question. One carries the power for the processor in low power mode. One carries the power to the sound card (or from the card to the speakers). Those two traces are too close together. So when power flows through the proc trace it induces electric current in the other trace, which causes the sound we hear from the speaker.
It is a problem of the design of the MLB. So the fix would be to isolate the two traces.
Just my idea.

NOISE ON MY AUDIO OUTPUT

I have a 50 foot shielded audio output from my imac and I cannot even listen to the output because there is so much electronic noise. I thought it might be the long run but if I hook my IPOD up it works perfect. has anyone else had grounding issues with the imacs sound card or imac in general because even when I run video out there is video noise also in my second display. I can't decide whether or not I need to take this computer in to be serviced.

Do you have the same noise problem with a set of headphones pluged into the iMac? Some here have noticed audio noise issues related to there optical mouse, is yours wired or wireless? A wired mouse should be pluged into the back of the keyboard! Also it seems that some have had to return the mouse for a replacement because of this issue. To test setup the audio as you had earlier and unplug your mouse! And lastly it couldn't hurt to reset your SMC follow the instructions in this link: http://docs.info.apple.com/article.html?artnum=303446

W500 audio noise while using audio output

Hello,
Few months ago I've bought Lenovo W500. After some time realized that when I'm using an audio output in sometimes I can hear annoying noise. I've checked it with different headphones (also professional ones) and other audi equipment. Always the same.
In the beginning I've thought there are some problems with my Alsa configuration (I'm using mainly Linux) but havent time to check.
Now I've spent more time for that. I've couldn't find solution, decided to check on Windows also - there is the same problem (with exactly the same audio files/youtube videos etc.)
Checked with different quality audio files - mp3, flac, audio cd etc. Always the same.
I can hear it very good in this moovie:
http://www.youtube.com/watch?v=SaUL_7H7r40
first time noise appears at 00:02 - 00:03 and then I can hear it in almost whole time.
If I turn off all audio players etc. I can still hear annoing, quiet noise from headphones (on both OSes - Linux/Windows).
Has anyone simmilar problem?
Any solution? My W500 is ofcourse under warranty but I need it at the moment very hard, so I hope there is some solution different than sending it to service :/
Thanks a lot,
Regards.

If you discard any software related problem, your problem is over hardware.
The only solution is sending to service and the will repair it for free. Maybe the will change the entire motherboard.
Best regards.

Noise floor of audio output

I noticed that the noise floor of the audio output in my 15" MacBook Pro is quite noticable when using external speakers. Is it just the way the sounds cards in these machines are or is there a problem with my specific unit?

connecting an external display or anything on the firewire bus raises the noise floor of the audio interface significantly. if that is your case, you're in the same camp as all macbook users ever since the intel transition. hope this helps.

Lot of noise from laptop audio output

I'm getting a lot of noise from the audio output of my Macbook Pro (early 2008) OS 10.8.5 when I connect an external firewire 800 drive that uses a power cord. I get more of the same noise when I connect an external video monitor. The noise is a digital hashy and whiney sound that modulates sometimes as what on the screen changes. If I use my Focusrite Scarlett interface the noise is amplified to the point that I can't work. The noise starts when the drive's power cord is plugged in. If I work off a pocket USB drive there is no noise. This is my work around for now. I'm using a power strip that has noise filtering. I have 2 different studios and I get the same noise in both. I've done a lot of trouble shooting and have narrowed the problem down to connecting a drive with a power cord to the computer. I have tried different drives too with the same result. Is there any hope of fixing this?

Can't say I've ever had any noise when starting the unit up over optical - if your DAC is designed for stereo only then it may be causing noise by attempting to play the 5.1 startup video's audio bitstream which is dolby digital encoded not stereo.

No audio output from either board

I have two machines running MSI boards. The one I am on now is a 7640 ver. 3.1 with Win8, the other is 7597 ver 1.1 with Win7. Both worked properly for a long time. This one stopped outputting audio last week. There are no yellow flags in device manager on anything, the control panel shows the Realtek audio is working fine, but no sound comes out. It was obviously the speakers, right? Wrong. I took the speakers from my daughter's computer that were working fine, put them on mine and nothing. I put the speakers back on her machine and they are still fine. A week later, her Windows crashed. I reinstalled Win7 and now there is no audio output on that machine! Everything says it's fine from device manager to control panel, but there is only silence.
What can I be missing? Help would be appreciated.

Well, as you have problems with two machines add both machine's details following >>Posting Guide<< as already said.
Reinstall in any case realtek audio: http://www.msi.com/service/download/driver-2584.html

Media Live Diva - No audio from on board RCA audio outputs

I am using the Media Live Diva (MS-7411). I am unable to route the audio to the RCA audio outputs built into the system board. I do not see an option to select these outputs in the setup. Any help would be appreciated as the MSI support seems to know very little about this board.
thanks,
George

I have been able to get output from the RCA on my board, make sure you're plugging into the Line-Out ones. I found that I have to play with the settings in windows to get them to work (connecting to a surround sound amp). I cannot remember off the top of my head but theres options in windows for playback devices: HDMI Audio, D2 Audio, Speakers, Headphones. Try each of these in turn, you can right click each one and hit Test and it will play a chirpy little tune in each speaker L+R.
Not that this only outputs stereo and may be quiet on some systems as it is a line level output i.e. it needs to be amplified.
Hope that helps.

Satellite laptop: connecting video out to projector causes hum in (headset) audio output

Our church connects video output from the laptop to a projection system and audio out (via headset jack) to a sound board mono channel (line in). Stereo to mono adapter. We get a significant hum in the audio whenever the video cable is plugged in. Doesn't matter whether the attached projection equipment is on or off, it's all about plugging the video cable into the laptop. Unplug the video cable and the hum disappears. Obviously we have tried all sorts of things to isolate the problem but it all comes back to plugging in that video cable. We made sure there were no nearby power supplies or other equipment that might throw out interference. Has anyone ever encountered this problem and have any suggestions? Thanks in advance for any help you can offer.

Using a Satellite PSBY1U laptop. Video out is not HDMI but the other (VGA?) connector. We are connecting audio out from the headset jack direct to a mixer channel. No microphone is connected to the laptop. We looked at every sound and video-related menu we could find and could not see any settings that would seem to be relevant to the problem (we changed lots of settings anyway and nothing helped). Naturally we played with audio volumes, different auto cables, etc. Bottom line is we get clean audio until we plug the video cable into the laptop, then we get a very prominent hum from the audio output. Video cable goes straight to a projector, doesn't matter whether the projector is turned on or off. The audio and video cables are never closer than four inches from each other. It's weird.
