Mac Pro :: Computer Noise / Hum In External Speakers
Dec 9, 2014
Just set up a new Mac Pro (8-core) and plugged in my old M-Audio powered speakers (about 10yrs old but still going strong!). I use a mini-jack splitter cable that outputs stereo RCA to the speakers, plugged into the speaker port on the nMP. There is a constant, low hum coming out of one of the speakers; it sounds a little like CPU noise and it is NOT affected by volume settings from the Mac or the speaker knob. It's the right-side speaker which is unpowered, connected to the left unit via speaker wire (the left unit has the power switch and audio inputs and is not affected.)
I've tried moving the speaker wire up and away from power cables (two Dell monitors directly next to the speakers) but that doesn't work; it doesn't sound quite like a DC hum anyway though. The speakers aren't heavily shielded (they usually pick up interference from an iPhone placed too close) so maybe it's always going to be an issue. I used to have them plugged into a 2006 Mac Pro via an analog mixer which I've removed from the chain.
I just bought a pair of the Rokit 5 external speakers. When I plug them into a Mac Pro (Tower) I get a high-pitched hum from the speakers each time I try to play a sound. So if I go into System Preferences/Audio, and I try to play a sound, the high-pitch is heard as the sound plays, and for a second or two after, then it goes away, and is heard again each time I try to play a sound. Same with when I play something thru iTunes or any of my audio apps.
If do the exact same thing playing from a Macbook, I do not have that problem at all, the sound is nice and clear with no high-pitch sound.
I have the speakers plugged in using 1/4 inch jacks to an external sound card (MBox), and this audio card is plugged USB into the Mac.
This may or may not be a stupid proposition, but here it goes: I have a Klipsch Promedia GMX 2.1a speaker system which I like very much. However, I was wondering if I could replace the existing satellite speakers with bookshelf speakers (like Klipsch RB-10 s). I'm hoping this will work because I want to increase the audio output of my system without spending money on an amplifier.
I noticed in the past week that when I scroll through a webpage I can hear a clicking sound (similar to the one from the MM) coming out of my speakers? This also seems to happen when I scroll through my iTunes library but in this case it's a humming sound, when the scrolling stops so does the noise. I've tried muting the speakers but the sound is still there, has anyone else experience this before?
I'm connecting my mbp to my new lcd sony bravia via dvi to hdmi lead and then connecting the sound via headphone jack to tv's 2 x phono, however i'm getting lots of audio noise bleeding through tv speakers underneath the main audio feed, i'm certain that its not a dodgy lead as iv'e tried 3 of them, however if i unplug the dvi lead the noise goes away, is it possible that the hdmi input is conflicting with the phono connection somehow.
I recently got a brand new 17' unibody MacBook Pro. Although it was brand new, there have been a flare ups. The last time I had the problem, (note: it is always while watching a YouTube video) this is what I captured before quickly closing the window. http://grab.by/1Gjt
That was New Years day. The first time I experienced this problem, I got nothing on the YouTube player and while skipping throughout the video to get it to stream, a noise that can't even be explained screamed out of the computers speakers. Today, I just had the same problem. I have no clue what it is except that I do know it comes from the speakers. Could anyone elaborate on if something similar has happened to you?
Yesterday my speakers stopped working. It's not software based, the audio drivers are working properly. Whenever a sound that is over a certain volume is played, you can hear a pop come from the speakers. For instance, if I play a song that has fluctuating volume, every time the volume goes up, there's a pop, and every time it goes back down, there's a pop. The volume the computer is set to doesn't effect this. Even if it's muted, there's still a pop that's the same volume as if the volume is turned up all the way. Any ideas what could be causing this?
I am trying to hook up the digital audio output on my cable box to the digital in on my dual 2.0 G5 running 10.4.9, 1 gig RAM. I have HDMI and component video out to monitor, but I use JBL creature speakers and sub for audio.
I have the propper cables and routing, sounds prefs set to digital in, and line out, to go to JBL creatures and first I get no sound at all. If I start AudioHijack and use same input and output settings all I can get is a hissing/clicking sort of sound. Same with using Soundsource and LineIn.
Audio MIDI Setup only shows or giveds me Built-in Audio for selections under system settings and properties for. Ausio Input and output show Master stream grayed out and I selected digital in and Line out for my sources and no change. Both ar set to 441000.0 Hz 2ch-24bit as well.
I have a Macbook Pro MC666ll/a. It is a core i7 15" with the AG screen. The issue I am experiencing is a random static noise coming from my speakers every now and then. If i have external speakers plugged in then the sound comes from the external speakers. Is this normal?
Occasionally I'll be listening to music or just changing the volume and a sharp popping sound will occur from the internal speakers and then they shut off. No sound can play it all. To fix the problem I just have to reboot and then the speakers work fine. Does anybody know why this happens?
This happens on my iMac sometimes and it just happened on my new MacBook Pro and I'm wondering if it's damaging the speakers in any way.
Edit: I don't remember what I was doing on my iMac to cause this, but I do know what caused it on my MacBook Pro. I was recording my canary singing (don't ask why) using Quicktime Pro, and then listened to it (it worked fine). I imported it into GarageBand to crop it and when I previewed it there to figure out where to crop the file, my speakers popped and GarageBand gave me a warning about the current track not being optimized or something. Note that never happened on my iMac.
so i love my new 27"; it's simply fantastic.... so far. i encountered a problem when i plugged in a 1/8 to RCA to go to my surround sound system. There is a loud humming sound coming from the speakers when i connect it. i tried to wiggle it and push it further to no avail. the sound was still there. i tried using another cable and the sound was still there. then i tried plugging in my headphones, and they WORK FINE! what the hell is going on and how do i fix this problem?
Today, my mac freaked out on me twice. I was watching something via Quicktime and all of the sudden the screen went black and green and started going crazy like it was twitching or something. And I got this loud noise coming out of my speakers. My MacBook is about 3-4 years old.
the external speakers (and the earphones) I use for my i-mac suddenly stopped playing sound from my imac. They do work though when I plug them to the i-pod. My imac speakers work perfectly. Any ideas what's happening?
i'm hoping someone can help me out on this little problemmy usual set up is a pair of speakers connected with jacks via an m-audio usb audio interface, with an external monitor connected via mini-dvi to dvi.now for some reason my audio interface has randomly broken (on a side note, could a power cut have somehow broken a usb peripheral connected to my macbook whilst it was asleep?) so i've hooked up my speakers to the line out to rca. Now for some reason, when i plug the mini dvi connector into my macbook i get an incredible amount of hum. not just a little, alot!
I have iTunes 10.6.1 (7) an Airport Extream Version 6.0 Airport Utility (600.92) That I use with two airport express stations, an Apple TV 2nd Generation with latest software up date. Also have Ipad 3rd Generation and two I phone 4's. Issue: After installing the latest Airport Utility software update I'm unable to connect to my remote speakers in iTunes. The speakers are visible in the pop up menu but iTunes times out when trying to connect. If I use remote to select Apple TV and then via Apple TV select my Computers Library I'm able to play music on the Apple TV / Home Speakers... but still not the Airport Express Stations.
When using remote on the iPhone or iPad the speakers are visible as well but I'm unable to select them... iTunes times out. I can steam music from that is on my iPhone or iPad to each individual speaker, but multiple speaker control is not available and the music from my library is not available. I believe the problem is in the Airplay feature of iTunes and I believe the problems arise when you install the latest version of Airport Utility. You can play on remote speakers, only one at a time, and only if you have the music on a stand alone device (iPhone or iPad)... in summary, bypass iTunes and you can be successful... marginally successful.
I'm currently in the market for some computer speakers for my aluminum macbook.Basically looking for the best pair of 2.1 speakers for under $200.I been eyeing up the Harmon Kardon Soundsticks II and Logitech Z-2300.One thing that kinda amazes me is that there have really been no updates to either of these sets of computer speakers.I really like the look of the soundsticks.What do you guys recommend?
One thing I love about the iPod Hi-Fi is that it has an optical audio input. It sounds incredible with the optical audio from a Mac, Apple TV, or sat TV receiver. I would love to have that for my Mac's connected speakers because Macs of course have digital optical out. However, are there any speakers out there, intended for computer use (size and whatnot) that have an digital optical input?
i have had my imac little under a week i been looking for any faults so can change soon as. I have 1 dead pixel, not yellow tinting, no buzz or hum noise but not sure about the hard drive it could be just me.
So how quiet should a imac be? i hear the hard drive working wen sometimes going through sites or doing program stuff nothing extremely loud though just quietish sounds that last few sec which different from the standard leave alone computer noise, which i think is normal with any computer but since i found at thread on hard drive noises i not sure now.
so question is really how quiet should a iMac be? i guess you should be able to hear it running but wen you are doing stuff should you hear the hard drive at all? just bit paranoid at moment since first mac.
I was just in my room minding my own business and I heard my iMac "shut down" but nothing happened, and I'm still able to use it like normal as I type this message.It seemed to quiet down my fans though, they are still running but much quieter so I guess in a way its a good thing.I'm just curious as to what happened here.
My girlfriend recently bought a 17" Unibody MacBook Pro (the one with the built-in battery). Yesterday, we noticed that the computer was making a noise from the left-hand side. It sounds like the hard-disk accessing information. Pretty much the sound all PC's make, however, we had never heard the machine make the noise before. She has had the computer for about 2 months. Our concern is primarily because my older 15" MBP Unibody is virtually silent and never makes a similar noise.
I have an aluminum macbook that is abou a year and a half old. It is making a weird scratching noise every few minutes. It sounds like I have DVD spinning in my disk drive and I am moving the laptop around. There is no disk in it so I am worried it's coming from my HD. Any ideas on what I should do?
ok, i installed 4gb (2x2)of ram in my alum macbook pro 2,4ghz 15" and in the 1 first time i didn't took off the battery but it went well and booted ok, after that i turned off the computer and the next time keeped making noises.
i tried put the old ram and it's everything ok, i tried both ram slots and memoryes and the 1rs booted ok alone but the second didn't, what is happening, it's the second ram damaged or have you another explanation?
My computer shows an upward facing arrow and makes a clicking noise when i hit the shift button, if i hold it down it switches into caps lock ... how can i get out of this mode?
