    I'm experiencing the same problem.

     

    Thunderbolt display with a 2012 Air produces static audio after 5 minutes approx.

     

    Doesn't appear to be any fix or acknowldegment from Apple to date.

    I have the same issue too, Apple have offered to replace the MBA, but I would rather go for a software fix! I have tried unplugging all USBs etc and still no joy. Hopefully there will be a firmware update soon that will sort it.

    Now with a second MacBook air 11" I am experiencing the same issue. Return the first display and on to the second display. Also now using a 11 vs the 13.  Both are 2012. Sound is slowly distorting and finally ends up with no sound from display at all with both MacBook Air 2012.

    IMO, not worth your time and hope in exchanging in the 2012 macbook air or the thunderbolt display.

     

    I bought the macbook air 2012 and the thunderbolt display the same day.

     

    static.

     

    exchanged just the thunderbolt display.

     

    static.

     

    exchanged the macbook air 2012

     

    static.

     

    went through two of each in 48 hours.  static LIVES.

     

    its clearly a software update that needs to happen.

     

    someone needs to go to an apple store.  grab a 2012 macbook air.  plug it into a thunderbolt display.  stream pandora (or whatever).  Drink a cup of coffee for 20 minutes.  guess what...

     

    STATIC.

    I'm wondering whether each time you got a new MacBook whether you ran the migration assistant to set it up?

     

    I did, and perhaps there is something transferring between MacBooks that causes the issue. The idea of using pristine apple store technology is a good one.

     

    Also if someone is brave enough, a clean format of a MBA would e a great test also.

  • robgough Calculating status...

    I didn't to a transfer when I got my new MBA, started it from fresh - using the factory install - and still have the issue.

     

    Note that I've tested with Maya44 (USB Audio) plugged into the Thunderbolt display and that seems to play fine, so it seems isolated to the USB audio within the thunderbolt display.

     

    (Though that's a "pro" external sound card, so may not be using the same type of drivers?)

    @sc0ttdav3y Pretty sure Migration Assistant is not relevant. I didn't use it (or transfer anything from an old Mac) and have the static issue also.

  • daz369 Level 1 Level 1 (0 points)

    same issue here. I upgraded from 2011 MBA (which has never had the issue).

    Within an hour of watching EyeTV on the 2012 MBA the Thunderbolt speakers are distorted.

    Changing back to the internal/onboard speakers and then back to Thunderbolt display audio, temporarily fixes it.

     

    I also called Apple Support who are wanting me to perform SMC reset and various other things, I hope to get some time later today to go through it with them on the phone.

     

    Not at all keen to go through the exchange with new MBA (and/or TBolt Display) as I dont want to have to migrate all over again, wipe the SSD, travel back and forth to Apple Store. So if not solved within 14 day return period, guess I will go back to 2011 machine.

    I have exactly the same issues.  Brand new Macbook Air and Thunderbolt.  Terrible static after 10 minutes of playing. Pausing audio or restarting iTunes gets it working again.  Ridiculous.

  • gouns Calculating status...

    I've contacted AppleCare, they had me go to an Apple Store with my MBA to test issue on T-Bolt display onsite.

     

    Haven't managed to reproduce the issue with my MBA plugged into Sydney's Apple Store T-Bolt display after 5mins and 2 HDD plugged at the back of it. The display had the exact same system info details than mine.

     

    Have called AppleCare again, they escalated and forwarded the issue to engineering for further investigation.

    I've pointed them to this thread for reference and am waiting for them to get back to me, will keep you posted.

    UPDATE:

     

    I've now tried three 2012 MBAs (all identical configuration) and two thunderbolt displays and the crackle exists in all cases.

    EDIT: note that when starting a new MBA-TDB combination for the first time it can take a long while for the issue to appear. My suspicion is that it'll not show up in-store.

     

    On the plus side my replacement TBD has a vastly better display and - when not crackling - better audio. So assuming Apple fix the audio issues, that's a win.

    wouldnt you think that of the thousands of employees apple has at corporate, somwhere someone is working on a new 2012 macbook air and hooked it up to their thunderbolt display at their desk and then streamed some sort of music while working at lovley apple....

     

    they would hear static!

  • rolandofromperu Calculating status...

    Hey everyone,

     

    Good and bad news. Heard back from the technician and he said Apple doesn't have a hardware fix for this particular issue yet. But they are investigating this problem and are likely to be releasing a software update.

     

    This is just a personal experience, I don't represent Apple and please don't take this as an official response. This is just what I heard from the technician who has been talking with the Apple advisors.

  • cseal Level 1 Level 1 (0 points)

    Thank you.  I notice that some people earlier seem to have attributed to being somehow USB related.  Static happens with mmy MBA 2012 when plugged in to Thunderbolt display WITHOUT anything plugged in to a USB slot.  I am trying to escalate this within Apple as high as possible.  My advice to anyone is don't waste your time swapping Thunderbolt displays or MacBook Air computers.  Best to spend time escalating this issue.

  • Marco Meneses 11 Level 1 Level 1 (55 points)

    Yup.  swapping anything out (MBA or TB) is useless.  Its the same thing.

     

    At least we seem to be getting somwhere.  Still amazes me how I have not seen something posted by someone on like MacWord, MacRumors, or MacHash, etc.  Doesnt some writer somwhere connect to a TB and stream music while they work?
