I'm so glad I read your reply. I have been SO frustrated. I have a mac mini (my third in a couple years because they keep malfunctioning and Apple ends up replacing them). I use it with a bluetooth speaker, and it's been great because I could declutter my desk and set the little Sony speaker on a nearby shelf. But when trying to Facetime or make a call on the computer, I get garbled Mickey Mouse sounds. Called support. Dreadful woman, nasty, insisted it was internet. NOT! Called back, got a nice guy, who said gee he had no idea why but had the same problem. No kidding! Skype audio was just fine, but not Facetime. So I tried using a headset plugged into the jack in the computer. That worked fine, but is annoying as the cord is rather short. Then I ordered an audio cable, plugged it into the computer AND into the speaker. Worked fine until the speaker decided to turn itself off. It had to be connected to Bluetooth on the computer, but I was able to select headset to have the sound come from the jack. Audio was find on Facetime. One day later, the sound started going nuts, and more annoying, a little speaker icon popped up on the bottom of the monitor, blocking stuff. Frustrated. Then I read your reply. Well I don't have a can of air, but can get one. Meanwhile I just cursed, unplugged the jack, and the sound icon disappeared. I set the speaker back to Bluetooth and do have sound. Now when I make a call, back to Mickey Mouse. But hey I can see the screen. In the middle of a writing job now but when it's done I'll take this Mac Mini into the store and complain. My impression is that Apple computers only work for about 7 or 8 months and then they start messing up. This last time I bought an extended warranty but frankly I wonder daily why I switched from PC. Of course they don't have Facetime, but apparently neither do I. Thanks for your help. I'll get the canned air and give it a try.
