Q: Sending mail always produces bluetooth error message. Anyone having same problem?

I have this same issue.  Warren, do you have Boom installed by any chance? I notice that I don't get the error when Boom isn't running.

Also, what application are you using to send mail?

I have the same problem whenever mail comes in.  I don't use Boom; I don't even know what it is.

Same problem. I don't use Boom. I do use a bluetooth audio device on occasion. No surprise, the issue disappears when I disable bluetooth, which isn't a good solution.

MacBook Air 13'' 2010

OS 10.7.1

I got the same problem.

Any one know have to fix this problem.

Mac Book Pro 2011 13"

OS 10.7.1

I use my headphones and the "A Bluetooth audio error occured." dialog box was getting annoying. My current workaround is to go into Apple mail preferences and set "New messages sound" to None and uncheck "Play sounds for other mail actions". With these settings I no longer get the annoying dialog box message.

I'm hoping to have a permanent solution that allows me to keep my headphones paired and sound with my new mail within a day or so.. or at least be able to explain the problem to Apple.

Solved! It was right in front of my eyes...

Go to System preferences->Sound->Sound Effects and make sure the "Play sound effects through" has "Internal Speakers" or something else besides your bluetooth device.

Evidently when you first pair your bluetooth headphones, OS X sets all the audio outputs to it. Since I made this change I am no longer getting the error messages while my bluetooth headset is turned off and still paired.

I am using Rocket Fish RF-MAB2 stereo headphones just in case this is relevant to you issue.

Replying directly since the real solution may not be seen further down the list.

Go to System Preferences->Sound->Sound Effects and change "Play sound effects through" to something other than your Bluetooth headset preferably "Internal Speakers".

Since making this change I have no problems with my bluetooth headset and Apple mail. Even if it's turned off and still paired.

Edit: Evidently the forums don't work this way. So sorry for the duplicate post.

Awsome.  @SpaceCoder's trick fixed the problem for me, too.  I chose "Selected sound output device" so that when I do have the Blutetooth headphones paired, the alert sounds will go through th headphones instead of the speakers.  It seems like "Selected sound output device" ought to be the default.

Yes! Thank you SpaceCoder, that is the real key change to make to truly address the issue, more effctive than disabling the device

Thanks @SpaceCoder. This was the solution to my problem, too. I had recently added a Bose Soundlink system to my older 2007 MacBook Pro running 10.7.2 and all Apple Mail sounds would cause this alert message to appear, even if I had deselected "Use as Audio Device" from the bluetooth menu and other sounds (music, etc) were going through my internal speakers.

Going into the "Sound" system preference pane under "Sound Effects" and setting that to "Selected sound output device" fixed it.

I can't say the solution was in front of my eyes, but I did find when I checked the 'sound effects' tab as per your suggestion that my system was indeed trying to play the 'whoosh' that Mail generates as a mail message is being sent through my headphones, so obviously would have a little difficulty doing this if the headphones were switched off.  I had been searching various web pages for a solution, and while it seems some people were blaming Mail for it no-one else seems to have zeroed in on the cause.
