Audio fading up and down

When I am playing track through Itunes my audio is fading up and down while playing it through my house amp. It use to work perfect before but don't know what's up. I did a upgrade that that my computer alerted me to do. Really need my music.

Are you sure you are posting in the right Forum? This is the Soundtrack Forum. It sounds like an iTunes problem you're having… in which case, you will get more & better answers posting over there.
(For what it's worth, this sounds like a problem with your audio system rather than iTunes. Does it affect other applications or devices, e.g., CD players?)

  • Audio goes up and down

    I created my first DVD with iDVD. I added a slideshow with background music.
    When I play the DVD on my DVD player (a Goodmans connected to my TV) I realize that every time the player skips from one photo to another the background music volume goes down then up again.
    The audio is low when the previous photo fade in transition then goes loud again when the next photo is fully displayed on the TV.
    It's awful.
    When I play the same DVD right on my Mac everything is right. The photos flow separated by transitions and the audio volume is always on the same level.
    I think this strange audio problem is due to the poor technology of my external DVD player. Is there any step I can apply to remove this anomaly?
    PowerBook G4 15''   Mac OS X (10.4.2)  

    It's a DVD reader fault, not a Mac fault

  • IMac spakers shift audio volume up and down...

    I play a song through iTunes and through the iMac's speakers, the volume sort of cuts out and shifts between volumes. Almost like it's hitting its limit in terms of volume. This only happens when the iMac's volume is at its peak, same with iTunes' built-in volume. I've never had this problem before, but could it be possible the speakers may have been somewhat damaged before I bought it? It was a Refreshed (open box) item from an Apple Store in San Francisco, CA.

    Thanks.

  • Solved: Attention T510 owners: Audio / sound volume goes up and down

    Hi all,
    I am a new owner of a T510, and have discovered the audio goes up and down when listening to music through the speakers, running on battery. I would like to get in contact with other T510 owners, who can test if their unit has the same problem - try this:
    1. Check all the settings in the SmartAudio control panel (using the newest driver) - making sure no EQ is set, nor VOIP settings or anything like that.
    2. Check that no plugin was loaded in the sound control options (I am using Windows 7, 32 bit).
    Now try and play this youtube song, and listen to the volume at around 40 seconds when the lead singer begins - does your audio volume go up and then down again when he stops? If you listen to the complete song, it goes up and down some more times.

    Edit  #1:
    I can unfortunately now add, that the problem is also there when using the AC adapter. It is so **bleep** annoying the volume fluctuates, and it is VERY easy to hear on the above link. Hoping to hear from other T510 users what their findings is. For information I can tell I am using the power plan called "Maximum Performance", in the power manager from Lenovo. The T510 model is a 4349-4JG.

    Edit #2:
    I have now had time to test it some more, using another HDD (didnt want to reinstall windows on my SSD, hehe) - and can hereby say that it seems to be a bug in the audio driver / SmartAudio control panel. Clean Windows 7, 32 bit, has the problems - but when you disable the VOIP function in the Smart Audio control panel, the problem disappears (actually it was just the VOIP function that was active before). If you then try to enable the VOIP function again, the "problem" does not come back (hence the bug comes into action now). After this test, I put my SSD back into the laptop, and tried to mess with the VOIP functions (again, had already tried to mess with it), and it did not do anything (hence the bug is active now). Therefore I reinstalled the audio driver - tried to check if the problem was there, it was. Then I did the same procedure as on the other HDD, tried to disable the VOIP (before I installed anything else and such!), and the problem is now gone. And the result now is that when I try and enable the VOIP function again, the problem does not come back (hence the bug is now active) = me happy
    In short terms:
    The bug can either have the VOIP enabled and you can not disable it, or it can be the other way around - it cant be enabled. To "turn" the bug around, reinstall the audio driver :-)

    Hi,
    Ive been having this problem with my Compaq CQ60-615DX for almost a year now. When im listening to music I can hear the audio going up and down through it. One sec itll be loud and  the next its like the audio being turned down (but the volume bar does not move). I also have SmartAudio with the Conexant High Definition. So, I see that you have figured it out. Ive tried to understand what you said but im not very literate with computers. Could you explain how to stop it step by step? I would appreciate it. Thanks.

  • I have been editing my films and spent hours fixing the audio levels. Everytime I close and re-open final cut audio levels go back down.

    I have been busy editing my film and for the third time now, i have been correcting my audio levels with each clip  - this takes me hours - and everytime I go back to the project, the audio levels fall back down. So everything i did previously was a waste of time.
    Does anyone have the same issue? Is there anything I am doing wrong here?

    Gosh, that sounds aweful close to the same problem people are experiencing with the undo bug. They don't know their having a problme until they hit Command+Z to undo their last change, and they can't, the undo command is actually grayed out in the menu. I understand if this happens, X is not auto saving your changes either. So, the next time you make all of your changes, check to see if your undo command is grayed out from the menu. If it is, duplicate your project to force a manual save. Then Quit X and reopen it and insure you project is intact.

  • How come when I view flash videos my videos stop, but the audio plays  and I see rainbow colored lines up and down the video.

    How come when I view flash videos my videos stop, but the audio plays  and I see rainbow colored lines up and down the video. I attached a image below.

    ATR, just to make sure you understand me, all my video clips in my folders appear as the first frame of the video clip when I view my folders as (small, medium, large)icons instead of lists, when saved as .avi files but when saved as .mp4 files, those icons display as a graphic icon of filmstrip with a musical note on it. I do have various other methods to open with (quick time, windows media, winamp or real player) but prefer real player because I like it's quick and easy trimmer that comes along with it, since so many of my videos are just pet antics where you need to clip off the boring beginning and ends of the video.
    I did go on a few of the icons and right clicked, Open With, and tried quick time and also Windows Media and it did nothing as far as how the file was saved for display, and they opened the same no matter which player I used...the actual video opens and plays right at it's first frame... but it's the way it is visually displayed in STORAGE that bugs me because it isn't immediately apparent to me what it is a video of (weddings, outside the house, pet antics)... it makes me have to actually title things and read titles where before I let it just be dates because I had the visual of that first frame as a reference. Obviously, this is a problem for unedited videos only, as anything I actually work with, I do give a title along with the date of the video.
    I also just realized this seems to be the way ALL videos that are wrapped in .mp4 are displayed, as my bloggie camera's videos appear the same way. Now I know why! My other videos display as .avi's so I see the frame. Puzzle solved. Guess I'll just have to learn to live with it, as it seems to be how things display with the various formats.
    Now I need to watch some tutorials to learn how this Premiere program works! It's all new to me, since this is the first time I've been able load any of my videos onto it. I haven't even been able to figure out how to trim on it yet!

  • How do I stop beats audio compressing the sound up and down

    How do I stop beats audio compressing the sound up and down.

    Hi Strung,
    I see that you are having some issues with compression and Beats Audio. I have done some research into your issue and will be happy to help. Here are a couple of links to HP Support Forum threads where they talk about the settings in the Beats Audio.

  • Trouble with Premiere timeline moving up and down multiple audio tracks.

    I have a project that has multiple audio tracks, aver 40. Only a portion of them are visible even when I use the new side scroll, I don't know the official name but the scroll on the side that Increases or decrease the size of the track so you can see the waveform. Even when I hide the video tracks and the other preview panels I still can't see all my audio tracks. How do I scroll up and down so I can see the tracks that I want to work on. You know, like in every other program I have ever used. 

    I feel like there's a bit of egg on my face. Rereading your message and messing with the horizontal bar I realized for both horizontal and vertical bars I grab in the center and drag left or right, up or down. There's a short cut for scrolling up and down your timeline tracks, hold down ctrl/cmd and then use the scroll wheel on your mouse, and that's what I was doing for my project last night. Ah growing pains of learning a new workspace.

  • Audio cut out and midi miss sync

    Lately I have been getting audio cut out, and the missing, 'error while trying to sync audio and midi'.
    I thought it was that I had too many instances of virtual instruments. So I mixed the song down. Imported that into a NEW song, with only one audio track, and then proceeded to try to do an organ overdub...Well Logic still drops out and gives me the message, even though there is NO midi information in this file...
    Then I noticed that even AIF or mp3 files, didn't play properly from the desktop preview mode. They stop too. Activity monitor doesn't seem to be showing anything overworking..
    Disk Warrior fixed some volume errors,
    Anyone have any ideas to try?

    I'm using a motu828. I disconnected the firewire connection, and ran audio from the headphone jack to the motu, and VOILA, no problems... Last year, I went thru two motu units, not really sure if they are the issue.
    I think it might be LOGIC's firewire circuitry. Apple techs couldn't find the issue, I had the G5 motherboard replaced. Another factor was I had 3 Lacie firewire drives (2 firewire 800, 1 400) I have had 4 Lacie drives die on me in the last 3 years. They are the only firewire drives I have, so I don't know if the fault lies with them, or the again Apples firewire circuitry, stressing the drives out???
    I also put a firewire 800 card in my system.
    I have now switched to an external ESATA raid setup. No more firewire drives. So far so good. Since I had the whole motherboard replaced, I don't know what that means in terms of MOTU connected via firewire..
    For now, I'm running audio out of headphone jack, using all virtual instruments, so I know it will sound better when I get firewire audio up and running, but I got tired of it cutting out every 3 - 30 minutes. I'm thinking about the apogee duet unit. But again if it's connected via firewire, I don't know where that leaves me..
    My G5 is three and half years old, perhaps it's tired and wants to be retired....
    The dark part of me wonders, if Apple computers don't start crapping out after three years of heavy use, or is it that technology, software, updates, push the hardware beyond it's capacity after a few years.

    Hi ...
    If you have moved the Safari application from the Applications folder, move it back.
    As far as the cache goes, there's a work around for that when you can't empty the Safari cache from the menu bar.
    Go to    ~/Library/Caches/com.aple.Safari.Cache.db.  Move the Cache.db file to the Trash.
    Try Safari.
    Mac OS X (10.7.2)   <  from your profile
    If that is corrrect, you need to update your system software. Click your Apple menu icon top left in your screen. From the drop down menu click Software
    Update ...
    ~ (Tilde) character represents the Home folder.

  • No Sound from Mac Pro, however, volume icon moves up and down

    Hello, I was using my 12 month old Mac Pro last night and it worked fine with sound as normal. When I powered it up today there is no sound coming from my monitor, but the volume icon moves up and down when I press the keys? I've checked in the Preference sound file and everything is set ok? I googled this problem and some people have suggested that there should not be a 'red' light showing in the digital connection on the back? However, I can see a red light, I've tried using my headphones in the front mini-jack and nothing? I disconnected the monitor audio cables restarted the Mac, there was then sound as normal if I used the sound keys. I re-connected the audio cable and it continued to play sound for 5 minutes or so, then stopped working again?

    I have a problem with my Powerbook automatically muting. If you read the posts, there seem to be a lot of people having this problem and no one can explain or help.

  • Satellite A300 screen keeps jumping up and down

    Hi,
    What is on my screen keeps jumping up and down, any thoughts, is this a problem with video card in Satellite A300?

    I have tried to install the display driver from the European website. During uninstallation I got a messgae to say failures occurred during uninstallation, and then during installation I got the message of Install package failure!
    I have my external monitor now connected to laptop, but in personalising display settings, I cannot get my computer to recognise that I have two monitors now, as both keep coming up with number 1 (Multiple Monitors) on ATI Mobility Radeon HD 3650, and they both have that degraded view, a bit like in safe mode.
    So in checking of device manager under display adapters I have:
    ATI Mobility Radeon HD3650
    and under Sound, video and game controllers I have:
    High Definition Audio Device
    Realtek High Definition Audio
    In this whole process I deleted a file that was previously here called
    ATI HMD...
    should I resinstall this?
    So I'm not sure if the new display driver has been installed? help.

  • My ipad has just faded out and i need it for highschool what do i do

    my ipad has just faded out and i need it for highschool .

  • I have an Intel based iMac that has just developed two small spots on the screen. One 1/8" circle at bottom and a tiny circle at top.  The fading on and off light isn't working anymore either.  Does anyone know anything about this?

    I have an Intel based iMac that has just developed two small spots on the screen - they look light brighter spots on the screen. One 1/8" circle at bottom right and a tiny circle at top right.  The fading on and off light on area surrounding the screen isn't working anymore either.  Has anyone else had similar problems?  Any solutions?  Thanks!

    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • Volume in Spotify is jumping up and down

    I've been using Spotify for some time without any problems. But on my new MacBookPro when I listen to any track, the volume goes up and down. When I setup normal volume it goes down so that I can hardly hear anything, then after a while the volume again becomes normal, later everything repeats again, and so on and on. What is the problem here? Other audio players and web sites work fine.

    Nobody with the same prob? No help from spotify? Its a bit disapointing.
    I have to say this is not a problem I have ever come accross before, but I have never owned a Mac! 
    These support forums are mainly for community support, if you want to reach out to the Spotify technical support teams you can do so via the online contact form. If you get an automated reply telling you to check out the community, just reply directly to that email and someone will get back to you.
