Noisy Audio Output

I seem to be getting a lot of what I would call "white noise interference" coming from my audio output. I also have an M-audio card installed which has the same type of sound but not as bad..anyone got any thoughts? many thanks

john, what m-audio card is it? and how is it connected?
any half decent card should really be (virtually) silent. if it's outputting noise when nothing's playing it's almost certainly faulty. make sure you've got the most recent driver.
can you try it with another mac? this would show if it's the card or the mac.

Noisy audio + audio output turns off / on - annoying

The audio out on a MBP (10.5.4) turns off after about 30 seconds, then turns back on when it makes any sound such as an alert sound, playing a song in iTunes / Quicktime, etc...
Case and point: Listen with headphones (or with your ear close to the laptop speaker) and do something that requires audio - e.g. just duplicate a file using Apple+D, you'll hear your alert sound. Then listen for 30 seconds - you will hear a faint hiss (with good headphones), then a click/pop as the audio turns off. WHY?
And this is really annoying: there is also a click/pop sound when you start to play something if the audio has turned off, i.e. the audio output has to turn itself ON again. Plus, in iTunes there is digital distortion and some very faint high-frequency hums.
I have my old PowerBook G4 sitting next to this MBP and it does NOT do this. So it begs the question: Why does Apple have to change things like this? Why change the audio output to turn off after 30 seconds? How is it that iTunes on a MBP creates digital distortion?
There is NO digital distortion within iTunes on the Powerbook G4. (I compared the same exact track from iTunes on the MBP to iTunes on the Powerbook G4.) There is NO digital distortion when playing audio through Quicktime on either laptop.
I don't get it. Apple/Mac should be improving their products. They bought Logic 8 from Emagic! That must mean they are interested in audio, yes? Then WHY cheapen the audio outs?
This is essentially a post to see if there has been any fixes for this problem, or to see if Apple/Mac really care or noticed. I hope it is the former.......

I have a brand new Macbook Pro Unibody 15'', which presents the same issues, but with some peculiarities. I have M-Audio reference speakers, connected with an analog cable minijack to RCA cable (note: they work perfectly when connected to the ext. firewire audio interface..) .
The weird thing is related to whether I have the power cord plugged in or not:
- with the magsafe power cord plugged in I only hear the intermittent "high pitched noises" described here: http://tech.kateva.org/2007/06/macintouch-review-audio-noise-in-new.html. They are apparently random .
- when I unplug the power cord I can hear all kind of sounds and noises: I can hear the harddrive spinning and seeking, a "fixed" background hum noise, more noises even when I type or move the mouse or use the trackpad.
UPDATE: When the external audio interface is not plugged in (it's a M-Audio firewire solo) I hear no more noises from the internal audio output ! Must be all related to some grounding issues of the audio interface.

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.

Default audio output has switched

having only recently upgraded to tiger (yeah yeah i know i'm late) i have noticed that my internet browsers and also realplayer defaults to playing audio out of "built in audio" output and when i switch it back to my firewire 410 output it doesnt work.
is there some OS related pref that i need to alter to get my browsers to recognise my audio interface? i dont know for sure that it is moving to Tiger that has done this but it seems likely as it never did anything like that prior to the upgrade...
any ideas?

thats the problem though, coz everytime i click it back to my firewire 410 in system prefs/sound/output i get no signal!
it only outputs from the default mac output, which means i either listen through that tiny speaker on the front, or have to run a mini jack out of that socket back into my desk.
the sound is awful though, really noisy and clipped. sounds like it was run through logics bitcrusher a couple of times..

Asrock ION330/Nvidia HDMI - No audio output

Machine was running archlinux and not been upgraded in over 6mths but HDMI audio worked fine. Decided to do a scratch build since all the changes in that time and have a nice clean system.
If it helps, this is what I install. Ssed this exact same install process for another Asrock ION330 and Acer Revo3610 (both same hardware) but neither use HDMI at all. Both VGA with either optical or analog audio. Both work with no additional config.

Get no sound output but also zero errors on any of the following commands. I should add that the receiver does not detect any audio coming in, ie it usually identifies how many channels of audio and type it is receiving.

Right click your volume icon in the notification area and select "volume control options". From there, you should be able to select the external speakers.
I hope that helps!

Is there a fix for Mountain Lion audio output settings after the laptop goes to sleep and wakes back up?

Mac Book Pro running Mountain Lion OS X 10.8.5 after the notebook sleeps audio and video does work (for example on YouTube). I have been able to temporarily work around this by toggling the settings on Built-in Output in Audio Midi Setup, Audio window between 2ch-20bit Integer and 2ch-24bit Integer. But this is a temporary fix until the laptop sleeps again.
When it's not working, all system sounds (emails "dings", delete file "swish", etc.) are silenced, and video playbacks on YouTube and elsewhere freeze and have no audio until the Audio Output settings are toggled then they all immediately start working.
Has anyone encountered the same? Have a long term fix for this annoyance?
I cannot upgrade the OS to 10.9 Mavericks yet because of a corporate policy - there is some conflict with 10.9 and our corporate VPN connection.

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:
http://allen-heath.helpserve.com/index.php?m=knowledgebase&a=viewarticle&kbarticleid=238
The ZED R16 is a great board but certainly not Plug' n Play.

Help! No Audio output In Logic Express 7

I have been running logic 7 Express with a MOTU Traveler for over a year now (with very few problems), and just this morning i have encountered a very puzzling problem. When i opened the song i was working on last night, i found that there was no audio output--just intermitant digital beeps at very high pitches (10-15k). i tried opening other songs; same problem. this problem does not occur when using the built in audio driver, so i was thinking it must be a hardware issue, but iTunes seems to output as per usual THROUGH THE MOTU so i'm really scratching my head here. hard drives etc seem to mount so the firewire port seems to be ok. i'm getting the same results (no audio playback and high digital pitches in Quicktime and Live as well...
has anyone with this setup ever experienced anything like this???!!!
thanks for reading,

Check you preferences in LE for what you have selected for output. Also, and I am not 100% sure, because for me this is always already set, make sure each track has Output 1-2 on the channel strip. On my setup, I have my Tascam US-122 set for both input and output, then my monitor system is connected to the US-122. Now I don't recall which, but I think it was Logic that wants both input and output to be the same device. I am pretty sure, because I know I have used both in GB. Also, on my US-122, there's a switch for mono, so my recording comes in both speakers, as well as a direct monitoring switch, with a separate volume control, so I can balance my recording with the tracks I am playing to, to my liking. I am not familiar with your unit, but I'd think it'd have some similar features. Hope this helps some, anyway.

Help, basic question, no audio output?

I have a Mac Pro running latest version of Logic Pro. I'm not new to audio software (come from a Cakewalk background on the Windows platform), but I'm relatively new to Mac Pro and Logic Pro.
I seem unable to get any audio output from my setup when using a Logic Midi Track (i.e. GM Device Piano).
My hardware:
Mac Pro
M-Audio Axiom 25 Keyboard/controller (connected via USB to Mac Pro)
MOTU UltraLite (connected via FireWire to Mac Pro)
M-Audio ProjectMix I/O (connected via FireWire to Mac Pro)
I can bring up the Loop Browser and play loops and place loops in the Arrange view but I can't seem to use my USB/MIDI M-Audio Keyboard to generate any Audio via the Motu.
Also, I can see the Midi events in the Logic Transport Window.
If I load up garageband the M-Audio & Motu Ultralite work just fine, so I'm confused as to what I'm not doing right in Logic Pro? It must be something really basic I'm missing.
Sorry for such a basic lame question, but I'm stumped!
Thanks, Rob.

well of course there is no official word on when an update to logic will arrive with a significant GUI overhaul. personally I hope that such a step is taken carefully.. this software is the backbone of many people's working life, so and big changes to the interface are hopefully being considered and integrated carefully.
I'd hope that a major overhaul to the logic UI won't just be cosmetic. there is a lot of legacy code left over from emagic days that do not make use of the latest OSX technology and so are not optimised. an example - look at how slow the screenset changes are. there is always a delay in response time to when you change a screenset, in some cases this can actually be slower than it was on older machines running OS9. as far as I can tell this is because it's all part of some custom graphics code in logic and doesn't make use of OSX quartz and probably not the graphics card effectively either. as a comparison, look at how incredibly responsive exposé is. it always seems to stay that responsive regardless of CPU load, so there has got to be a way to make the GUI features of logic perform just as snappily as the system ones.
same goes for the painful, annoying delay in mouse click response time, which is worse since OSX than it was under os9. a rewrite of logic's UI will hopefully sort this problem out too.
these things may seem like irrelevant nitpicks, but trust me, when you become a power user and you are cutting audio and throwing parts of your arrangement around like nobody's business, the sticky slow response of the GUI really penalises you.

Help Please!! no audio output device installed?

Hi. I have a satellite A215-S4757 last night I installed some windows updats went to bed because it was going to take awhile. When I got it had finished and was in sleep mode. When I turned it on I noticed the sound was on mute. Or I thought it was. When I attempted to turn the sound on I recieved the message "No audio output device installed". I updated BIOs 2.30 but that didnt work. If anyone could help me out I would greatly appreciate it!
Thanks

Try this! Looks like you have Realtek audio. I was having the same problem until I installed the updated Realtek driver directly from Realtek site.
As many users have posted, I was having this problem with my Satellite L505-S5990. I tried most of the suggestions I could find here and on the 'net to no avail. I was surprised to see that this problem affected many laptop brands - even as far back as Windows XP!!
Last week I think I finally found the answer (or at least Realtek did). My laptop has Realtek HD audio, and the drivers that came with laptop seemed to be the culprit. I checked the Realtek site last week, and they have an updated driver, dated 3/30/2010, for Windows 7 as well as other versions of Windows. It is Version 2.46.
I downloaded and installed these drivers, switched back to going into sleep mode rather than hibernate and - so far - the computer wakes from sleep with sound intact!!!
Hopefully these drivers will work for others.

I can't select "audio output stereo" on a track in the arrange window

When I create a new song, in the Arrange window I can
choose "audio output stereo" for a given track, and
access the mixer's output from there. Fab.
When I open a song that I oringally created using Logic 5,
"audio output stereo" does not appear.
Is this something about the file format?
(a) is there something simple to do to enable that for
older songs, or (b) is there a way to convert older song files to LE7?
thanks,
fred, san rafael.
[email protected]

Sorry, je suis un idiot.
FYI. I went into the Environment window and found "Output 1-2"
to be un-checked. Checking it now makes "audio output stero" an available option in that song.
Thanks for listening.
