The microphone and speakers on Apple laptops are located in the lower case, not in the display. What you are noticing are the permanent magnets installed in the display to keep the lid closed without a mechanical latch.

If you look in your headphones jack, is there a red light on? If yes, then you have Digital Out on, and this messes with the speaker configuration. There is a thread here, which has some possible fixes. Update Taking a toothpick and fiddling around inside the jack has solved the problem for some, you should try this. (Don't break the toothpick inside :) ) ...

Did you check the settings in the app "Audio MIDI Setup"? It's in /Applications/Utilities. Sometimes the settings there can get out of whack.

Loudspeakers use permanent magnets, unaffected by electricity. If you pass an alternating current through a coil of wire, it will induce a magnetic field in the coil. If you put 2 magnets in close proximity, opposite poles will attract, similar poles will repel. Conversely, if you move a coil of wire near to a magnet, it will generate electricity. This is ...

Sometimes changing the sound output from your system preferences > sound panel will reinitialize the connection to your hardware. If you only have one output device available, try installing soundflower, just to have a second output in your list that you can cycle through. an image is here: http://i.stack.imgur.com/h8GfV.jpg Also: setting things back up ...

Try the Boom system-wide volume booster tool. While it's not free, it is cheap: $6.99. See reviews here, here, and here. Below is the description from the product page, and a screenshot: Boom is a simple volume booster and system-wide equalizer that lets you boost the volume of your Mac and your music files. Using Boom is simple. You know the ...

Pretty sure it can't be done with the built-in headphone jack. What you could try is getting a USB soundcard (one example, but there are lots out there for $20 or so) to plug your headphones into. That should give you two options in the sound preferences. PS, if you option-click the speaker icon in the menu bar, you get a quicker way to swap inputs/outputs ...

According to Wikipedia: The AirTunes part of the AirPlay protocol stack uses UDP for streaming audio and is based on the RTSP network control protocol.[12] The streams are encrypted with AES, requiring the receiver to have access to the appropriate private key to decrypt the streams.[13] The AirPort Express' streaming media capabilities use ...

There are several bluetooth solutions, that should be useful: Phone Amego ($29) - This should do the trick. Works and has interesting features. I recommend it. BluePhoneElite 2 - No longer developed and supported. I see almost everything vanished, but I think you should be able to locate a working copy somehow. Edit: As of OS X 10.10 Yosemite and iOS8 ...

You generally shouldn't bring any electronics into an area with that much water vapor on a regular basis unless they are labeled for such use. If you search for waterproof speakers on Amazon you'll find many affordable options, including several that are designed specifically for iPods.

Gently pluginng the headphones in and out of the jack solved the issue.

Output statistics such are usually reported as Watts. This sounds like what you are looking for. This is, unfortunately, a totally worthless data point, and the reasons why are beyond the scope of an answer on this forum. Your best bet for measuring output, such as decibels/watt/meter, is an SPL (sound pressure level) meter. This would give you the best data ...

When a USB device is hot-plugged while VMware is running, I often see a dialog from the VM instance asking if the device should be attached to the VM or to the host OS. It's quite easy to miss this dialog if you have other applications running or if the VM is in a separate workspace. And until the dialog gets its answer, the device isn't attached to either ...

Try switching back to your internal speakers with [alt]-clicking on the speaker icon in menubar. Many interfaces don't support volume adjustment and thus the control becomes greyed out.

Yep this is a new feature included in OS X Yosemite which will be public in Fall 2014.

Try quitting CoreAudio from activity monitor, forcing it to relaunch itself.

My speakers are now on my wifi. A bloke called Jason from Pioneer called me this morning and told me to ignore the manual and instead to do the following: Turn the unit off and unplug it from Ethernet and power. Plug the power back in and turn the unit back on — wait for it to power up again. Plug your iOS device (assumes you have one, and that it is ...

No you can't. And as far as I can tell (searching the App Store) there are no apps that can help you. Even if there was one you wouldn't be able to open the audio file in Mail without using QuickTime, and that will always lead to the audio file playing through speaker. Best you can do is have a pair of headphones with you and hope something changes in ...

Audio MIDI Setup to the rescue! Open Audio MIDI Setup which is located in Applications > Utilities. Click the + icon in the bottom-left hand side and choose Create Multi-Output Device. When the multi-output device is selected, click the Built-In Output, and the Cinema Display's output audio devices. After this is done, open System Preferences and ...

I had this problem and solved it by plugging in (and then unplugging) my iPod headphones.

Samething here, I plugged in my headphones and jiggled them a little bit while inside and then pulled them out halfway. Once I did that I could see the volume slider appear and the volume could be adjusted up and down. I pulled them out all the way and they volume went grey again. Pushed the headphones back in and then pulled them out and now everything ...

Balancing changes the volume of both speakers at the same time. Since it only changes the volume, there is not manipulation of the stereo effect (sound shifting). For example: If you play a track that plays on the left speaker and then shift the balance to the very right - you will not hear anything. If you play a stereo track, you will only hear the right ...

If your stereo does not register that it supports the A2DP profile, then it likely will also not handle A2DP communication. It is not as simple as finding an app that will "fix the problem", because the problem is likely that your Stereo does not support audio playback. The level of difference between A2DP for audio playback and HSP for maintaining calls is ...

No - the iPhone will only send audio to one of the two, with the physical speaker it is attached to being the preference. You could possibly have the physical speaker output sound and send it to the Bose wireless but that's the only thing I can think of.

It might think that you have connected an optical cable (is the port glowing red?) or that you are sending the sound through HDMI instead. If it's the former, try connecting your speaker/headphone cable and wiggle it a little. If it's the latter, check the sound settings in System preferences.

This answer is based on a comment on @morphos' answer. Headphones work, but it doesn't work when I take them out. The prefpane changes to "Digital Out" of type "Optical digital out port" and doesn't let me even change the volume. (the volume controls faded and hitting volume keys shows a crossed out sign) That means that it thinks you have an ...

1) I think it's dependand on the speaker set you're using, but I don't think so. 2) No, you can change your audio output in a simpler way: Hit Alt resp. Option Click on the volume icon Select your input/output sources

The simple answer is - not many. The iFixit teardown of an earlier model (mid-2010) suggests 1-2 watts. The teardown of the 2011 model says nothing has changed since then.

Airport Express + Waterproof speakers (mounted). Use AirPlay to play from your iOS device or Mac (iTunes). That way you can keep your Mac out of the bathroom if you want to play from iTunes.

it a little bit odd, but the Sound preferences in System Preferences only shows the controls for the currently selected device. If you plug in headphones for example, it only allows you select and alter the sound preferences for the headphones (and doesn't even show the internal speakers) It maintains different sets of preferences for each output type. ...
