Audio sound distorted since 10.6.3 and Pro Apps 2010-01 - bug iTuneshelper

As of OS X 10.6.3 and Pro Apps Update 2010-01 (FPC 7.0.2) I was encountering in both video sound and music sound tracks odd and somewhat unpredictable audio distortion (wrong pitch and left and right stereo sound running out of sync).
This problem seemed to pop up around the end of March 2010.
I have determined that it is related to iTunes 9.0 which has placed in my startup items iTunesHelper which is a startup item, just after AdobeResourcesSynchronizer, iChat and Stickies. I am not certain if it is the order of the startup that introduces the problem or the version of iTunes (which currently is now 9.1).
If you have this item in your startup, just delete it and perhaps your audio problems will go away.

Had the same exact problem. Just got off the phone with Apple Support. The tech asked me to create a test administrator account under Accounts in Systems Preferences. Then log out of account you are currently using and log in to the test account. If you are like me then you will find Adobe Reader and Adobe Acrobat under Applications. Open Adobe Reader and choose to update it. I actually did not have to choose anything as the program began to update both itself and Acrobat Pro automatically. It will take about 10 minutes, depending on speed of internet and computer speed. Once completed, then logout and log back into your normal administrator account. Both programs should now be updated and you can use them. Delete the test administrator account you created. And, good luck on that school work.

    Why does music sound distorted since IOs7

    Reset the device:
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
    If you are using an iPad case, make sure the speakers are not blocked.

    I have a macbookpro 2009, core2duo, 8 Go Ram, SSD internal, sound cart external Motu UltraLight MK3 (Firewire connection).
    1) Before with OSX 10.8 Mountain Lion, I never have this problem.
    2) There is 1 year, I install Maverick and I have sometime (one time on 2 or 3 hour) a little crash sound (silence or crash sound since 2 seconds).
    3) There is 6 month, I add 4 Go Ram to have 8 Go Ram.
    No change, after that I have the same problem.
    4) All Driver are update.
    (On internet, I see it's a problem that many people know but without a good solution, apple don't give the solution, it's sad...)
    5) I see on internet that Yosemite resolve this problem.
    I Install Yosemite 10.10.1 on an external hard disk (USB connection)... and I boot on it
    no change :-/
    6) I change my external sound card with an RME Fireface UCX (a nice sound card, I like it)
    I think at a moment it's better because I haven't had crash sound since 5 day (5 x 5h use it)...
    but the 6 day, there is a big crash sound since 3 secondes.
    Why ?
    At this moment there is : Traktor + Live + TotalMix (RME) + Digicheck (RME)
    Too much prg run ?...
    But I see that No overload cpu and 3 Go memory free....
    Just for information :
    Before with Motu Ultralight MK3 the message error (on consol) with crash (1 on 2,3 hours) :
    kernel[0]: IOAudioStream[0xffffff8021ab3200]::clipIfNecessary() - Error: attempting to clip to a position more than one buffer ahead of last clip position (da55,e3c)->(da59,123c)
    Now with RME UCX the message error (on consol) when I have the crash (just one on 6 days) :
    (what is it the "XPC" ? and why this question "Please switch to XPC..." on logfile ?)
    who will have an idea to resolve that ?
    Thank you very much for your responds

    No difference. I closed FFox installed Flash apparently and then went to Adobe - Flash Player where no animation nor indication of what version of Flash I do have installed. Chrome on the other hand displays this information. FFox plugins page shows that Flash is installed and set to always activate.

  • Sound alerts not working in Mail and Ichat apps since upgrade to 10.4.9

    I just noticed my Sound alets not working in Mail and Ichat apps since upgrade to 10.4.9.
    I'm using soundsticks which is playing sounds thru quicktime, itunes, etc but my alert sounds for getting new emails and IM messages is not working. I get the quick "white flash" on the screen instead. I checked the prefs on both apps and it is set to give me the alert sound, I can even test it in the ichat pref when I change the new message alert sound it will play it thru my speakers but when I get a new message in either app it just gives me the white flash.
    I'm read that it can be an issue of not having the balance in the system sound pref set the middle, so I checked that, restarted, all that but still no luck.
    I really like the sound alert features because I can be in another part of my house, turn the sound way up and I'll know when one of my clients is trying to reach me but now I can't do that.
    Any ideas?
    Thanks in advance!

    Ok, weird, strange...did ONE more restart and now its working fine...who knows?

  • Need help with audio sound distortion

    Hi,
    I have a HP G60 Notebook PC with Windows 7 which I bought two years ago; recently I noticed when audio is being played, the sound distorts through my integrated speakers (no external speakers) in the laptop. I was wondering if this is a hardware issue or a software one and where would I be able to get it  fixed?

    having problems with sound distortion,very slow sound as well as the image being slowed down as well. What can be done about this without having to get computer repaired?

  • Flash CS6: Why does some audio sound distorted?

    When i publish my flash video, the audio sounds very distorted and it seems as if the bass is gone or something wrong. Here is the weird part; some audio that i used before this works perfectly. When i preview the audio in flash cs6 and in the library it also sounds normal. How do i fix this? I tried editing the audio settings via publish settings, no luck.

  • MacBook and Pro Apps

    I am considering the purchase of one of the brand new MacBooks that were released today and I am wondering if Pro Apps like Aperture and Final Cut run well on the MacBook? Is the Intel Graphics card alright to run those programs? How about Photoshop and Flash?
    Also, I would like to know someones thoughts on the MacBook display. Is it nice and bright? Clear?
    I have also heard that the MacBook gets noisy when viewing sites such as youtube or other flash sites? Is this true?

    Aperture 1.5 ran very well on my 2.0GHz Core Duo MacBook while I was using it. In the end, I was forced to move my 57GB Aperture library to my iMac, I couldn't afford the hard drive space on my portable. It should run just fine on one of the new MacBooks. Neither Color nor Motion will run at all on the MacBooks. They require a different video card. While DVD Studio Pro, SoundTrack Pro and Final Cut Pro will run on a MacBook, keep in mind that Apple does not support it. You won't be able to go to them for any technical help and the folks here might not be able to offer suggestions since they're not experienced with the same hardware.

  • Strange sound distortion since update (but only some files and Bluetooth)

    Hello Community!
    My Xperia Z1 compact got updated to Lollipop (14.5.A.0.242) this morning. Moreover, the Walkman got updated to 8.5.A.3.3. From then onwards, some music files are distorted when played with Walkman, but only when played via Bluetooth.
    This does not happen when played with another player (tested with VLC app). It seems to be also restricted to a special file type. Nearly all my music is stored with AAC. The files that have the problem are however only the AAC files that use the profile HE-AAC (AAC+ i.e. with SBR). If I remember it correctly, I created these files with Winamp.
    Could you please look into this problem? I like the Walkman player more than Google Music or VLC and don't want to convert all my HE-AAC music to something else.
    If you need any more information, do not hesitate to ask. Best regards and thanks in advance,
    Mattes

  • Audio sound distorted through headset

    Hi, I am having an irritating problem with audio distortion through headphones on my 2 month old Z2
    Sound quality is really tinny and unbalanced and is almost entirelly cancelling out any vocal. Imagine listening to a song being played in the next room.
    External speaker play back is fine.
    Headphones which are Marshall Monitors are working fine on other phones that I have and work fine on the Z2 for phone calls.
    When headphones are being used for music -
    It is happening via various streamed live radio and music players inc Deezer, youtube and BBC tv iplayer, cached music on Deezer, as well as mp3 format music on the SD card.
    There doesn't seem to be an issue with phone call quality.
    Software is all up to date following a factory reset.
    This all leads me to think its a software issue with audio playback rather than hardware.
    Help please!

    Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
    Have you added any sound effects via Settings > Sound > Sound effects? You could also try to change the audio accessories via Settings > Audio accessories > Other, to see if you experience the same behaviour.
    Otherwise, you can also try another pair of headphones/headset to see if same thing occurs. Prefer a Sony headset.

  • Sound distortion since OS upgrade?

    Am I imagining it, or has anyone else noticed a deterioration in sound quality during phone calls since the latest OS upgrade?
    I have a BB 9300 3G and the OS is 6.0 bundle 2949.
    The sound is fine on speaker and on headset, just a slight distortion on the handset which I am convinced started after the latest upgrade last week.

    Thanks for the suggestions - I had done them all except dropping back on QuickTimes - I was already at 16 bit and have backed it off to 8 bit. At least this morning Eric Clapton is stuttering c-c-c-c-cocaine. It does seem better.
    I am still having the problem with large applications impacting iTunes - but knowing this is a bug and not a problem I am having with my PC, I have stopped hyperventilating.
    Stay tuned (no pun intended)

  • Sound distortion since flash player update

    since the update a few months ago the flash on our site distorts sound quite badly. They are small sound files taken from the database. There were no problems before the update and it seems many people have had and still have a problem so I think the problem is with the player but Im wondering if there is anything that can be done in the flash to get around this?

    I had the same problem(I couldn´t see myself neither the other person, but the other person could see me).
    I have solved it doing this:
    Log into your Gmail account > Settings > Labs. Enable Video Chat Enhancement lab. Save change. Restart Gmail. Test video.
    And now I can see myself and the other person.

  • Audio sounds different since 8.1 update

    My concern is with a HP Envy Touchsmart m6-k015dx Sleekbook. I don't use this laptop for too much because I mainly do light schoolwork on this and leave most of my other tasks to my more powerful notebooks. I first noticed something different since i left this at a friends house and his little bro managed to update this to windows 8.1. Luckily, none of my work was affected but i immiediatly noticed a difference in sound( i am very "attuned" to sounds i guess) and it just did'nt sound the same. I checked the settings and equalizers and everything was set exactly how i had it. I know the built in speakers are already bad but when i hook it up to speakers, it also sounds different and my friend agrees with me. When i check for driver updates, there are none. And recently(like 2 days ago) ill hook my speakers up and the song will play wierdly and start stuttering whenever heavy bass starts playing. I hooked my speakers up to my Envy 15 and Razor and i do not encounter this problem. Im wondering if it's just a driver needing an update or if my audio card is shot somehow. Pls. tell me i can fix this, i mean it's not that big a deal but i hate when things dont work!

  • Keynote to Dropbox or SkyDrive (broken files since update to ML and latest app version)

    This is causing me real pain, and I don't know what it is that is broken.
    Since the update to Mountain Lion and updating to the latest versions of the iWork apps on both my iMac and my iPad,  when I try and copy a keynote file into either my Dropbox or SkyDrive account (there are reasons for using these, so don't say, use iCloud please) whereas before the file would copy across whole, what I now get is a folder with all my inserted media (video/photos) and a broken up template.  The file is not transferring across whole.
    Is anyone else experiencing this, is it a specific ML or updated Keynote bug.  It's a real issue as I need to share a presentation and can't as the two file repositories I use for collaboration are now not working with the updated application.

    It sounds like the "Package" bit isn't being set.  Suggestion (1) is just routine housekeeping, run disk utility and make sure the disk is good and the permissions are repaired.  Suggestion (2) is a workaround : zip the keynote file and put that in dropbox.  Take it out of Dropbox then unzip to use, zip and put back in dropbox to sync.   It's not as convenient but it should workaround the problem.

  • I'm having some Audio Issues involving my headphone jack (air and pro)?

    Ok, so, this is pretty weird.
    I have had two macbooks thus far (a 2011 macbook pro and a mid 2013 macbook air)
    I replaced my pro in 2013 due to a separate issue.
    Anyway, I have been consistently having an issue where any type of headphones I put into my computer eventually begin to lose sound in the left earphone - but still work fine on other devices.
    I.e, I'll get a new set of headphones, use them for a week, and a week later, no sound will come from the left port - but only when using my air. It is most definitely not the headphones.
    It's not the output balance - when I set the balance all the way to the left, no sound comes out, and the problem continually reoccurs with every new set of headphones I get - on TWO different computers.
    The same issue happened on my pro, and happens in my air.
    Am I like, inserting the headphone jack in "too roughly" or something? What's going on?

    some headphone jacks arent the exact right length and the contacts miss

  • How can I connect my new LG Sound Bar NB 3531A with my MacBook Pro Mid 2010 via Bluetooth

    Hey,
    bought a new sound bar and want to connect it to my MacBook Pro. When start pairing an error shows up telling me to check the Bluetooth range and so on. When I try to connect without a code (0000) there is a connection but it´s not possible to use the bar as a stereo headset in the bluetooth menue.
    The Sound Bar should be ready to play because I can use it with my iPhone and on Win-notebooks.B
    There are no system-updates availabe and I´m using OSX 10.8.4. Can someone help?
    Best wishes from Germany
    HolliHollsen

    It seems that my bluetooth driver crashed or anything. Tried it with an other MacBook and worked fine. Called the Apple- and LG-Support.
    The Apple-Supporter told my to reinstall my OS X. Crashed. I´ll start a complete new installation today.
