Dear aphiffer and ALL PEOPLE HAVING "SOUND" ISSUES WITH MAIL!!!!:
in answer to your question, YES, but the problem is multifactoral....myself, and several others, some who have mountain lion, and others who do not, have been having various "sound" issues with mail, specifically: sometimes, they don't get any sound for outgoing mail, sometimes none for incoming, sometimes none for both, and sometimes, like you, they get too much sound, even when they are not doing anything. if you look to the right you will see several, under "more like this", all related to sound issues on mail. I personally have called apple tech support at least 3 times, and taken my computer in at least 4 times, regarding this issue (for me, it was either a complete absence of sound, either incoming or outgoing, or just no incoming sound, but to me, all of our issues, either excessive sound or no sound, are obviously related somehow, and a glich within the mail (and/or cloud???) system....one time, i was told by apple tech support that the techs were "aware of the issue, but it was a "low priority"!!!! this was one of times i called...the last time i took my computer in, the genius bar guy said it had to do with having to reset the "permissions", which he did, and my sounds came back. He showed me how to do it, and i also posted on one of the other discussion groups re: absence of sound...the other times, they tested it, and of course, it worked while i was there, and stopped working when i got home...i am thinking it has something to do with their connection at the apple store vs. home (i have wireless connection)...maybe they are directly connected to apple somehow..don't know. here is what he told me to do:
go to the spotlight (looks like a spyglass in the upper right hand corner of the screen)...click on it, and type in utilities, then go to disk utilities, then highlight (upper left of box that comes up) the words "Macintosh HD"...then click the "reset permissions"...it will take a while...this worked for me, but didn't for some others....someone else posted another fix, having to do with the audio midi settings...type in "audio midi" in the spotlight window (as i described above for "utlilies"...then highlight "built-in output", then click the down arrow next to the "format", change the setting to anything, other than what it was originally set on (mine was set on 44100.0 Hz). they said you will hear a cacophany of sounds...when the sounds are finished playing, you can set it back to the first choice that it was originally set on. this worked for lots of people, especially those with Mountain Lion, but not for me...someone else said the only thing that worked for him was doing a reboot of the entire computer.
even though some have excessive sounds, like you, and some have no sounds, either partially or completely, it is all still "sound" related, which tells me the problems are all related within the apple mail system. totally frustrating...i have been fighting with this problem for 8 months plus now, and many others have too...APPLE NEEDS TO FIX THIS NOW!!! LOW PRIORITY, my BEHIND!!! Not for all of us!!! This "sound" issue should be working properly, and if it isn't, they should fix it, period!!! the last technician i spoke with at apple assured me she would make a report on all of our behalf, as i told her there are lots of us out there, ready to throw the computers out the window, due to sound issues....
i suggest you track some of these discussions, and look at some of the other discussions related to sound issues, as i mentioned...maybe if we all share info, we will find something that will work. looks like they are not going to do anything about it, any time soon!!!!
hope one of the above "fixes" works for your problem!
joyce (joyceji)
