Headphone Audio History

I haven't yet tried to recreate this to figure out exactly what happend. The gist of the story is this

After several days of using my MacBook Air (mid 2011) with Mac os X 10.8 (Montain Lion) I decided to plug in a pair of Apple white In-Ear headphones with mic and suddenly I am listening to a stream of boing boing boing swoosh boing boing boing .... etc. As near as I can tell it was an alert sound for every email I had received in the past several days, and a swoosh for every email I had sent. All told it probably lasted 40 seconds. Very odd indeed.

Originally I thought something was going wrong with the audio, but I really think it was all the stored up audio alerts for the past several days.

I am going to try to recate over the day and see what happens.

MacBook Air, OS X Mountain Lion

While I have had no success in actually recreating this in headphones, I awoke my MacBook Air from sleep today, and off it went agian, this time through the built in spearkers.

"Boing, Boing, Boing Boing, swish, swish, Boing, Boing" etc. Probably only 10-15 seconds worth this time, still very odd.

Same problem here on a Macbook Pro Retina. The audio for alerts does not work at all (alerts only, other audio is fine) until I plug a pair of headphones in and then remove them. This starts 1-2 mins of alert sounds which seem to have been stored somewhere. I would like a permanent fix to this as I shouldnt have to plug a pair of headphones in every day to hear th alert audio!!!

I have the same problem - notification sounds only play with headphones, and they appear to be queued up so that they all play one after the other when the headphones are plugged in. So Monday morning, I get a nice ~60 second symphony of "bling, bling, swoosh, bling".


Considering Notification Center was one of the major features in ML I am surprised this made it to release.

Have the same problem with MBA13. Found a fix suggestion to change the audio inputs & outputs to 32bit float instead of 24 bit fixed from the Midi settings.


Did this myself the other day, and just making the change triggered the same thing, so it might be connected, haven't had the issue since, but not quite conclusive about if this actually solved the problem for good or not. I'll test it for another week to see if the problem persists...
