MacBook :: External Speakers Line Out When Using External Display?
Apr 5, 2010
i'm hoping someone can help me out on this little problemmy usual set up is a pair of speakers connected with jacks via an m-audio usb audio interface, with an external monitor connected via mini-dvi to dvi.now for some reason my audio interface has randomly broken (on a side note, could a power cut have somehow broken a usb peripheral connected to my macbook whilst it was asleep?) so i've hooked up my speakers to the line out to rca. Now for some reason, when i plug the mini dvi connector into my macbook i get an incredible amount of hum. not just a little, alot!

Line-in external tape recorder produces VU sound level fluctuations but the sound doesn't come out the internal speakers. iTunes and Internet sources play OK.

I have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.
I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

After upgrading to Lion, there seems to be very little sound coming from my external speakers. Speakers work with other devices but not so much with MacBook Pro. In iTunes, the volumn slider is maxed out with the speaker volumn on the keyboard maxed out too. Used to blast out the house, but not now.Â
Don't know if it's as a result of the upgrade or not. I did a PRAM reset but still nothing.Â
Info:
Mac OS X (10.7.3), external speakers are harmon/kardon

I've just purchased a new sr macbook pro 2.4 ghz. when i plug the macbook pro to external speakers, the quality is really bad, no bass, just high tones. I allready checked the equalizer in Itunes and I turned the bass all the way up, but the sound was still horrible...
When I connect my macbook pro to a tv (via dvi to video adaptor) The sound of the external speakers goes even worse. The adapter causes like a weird tone in the bass...
does anyone know how to fix this?

Okay, So i have my Unibody Macbook Pro (late 2009) hooked up to external speakers (RCA Home Theater system with a standard audio cable). Everything works fine and there is no buzz or sound except for the music of course until I plug my printer in. I know the obvious solution is to unplug the printer when listening to music but the printer is shared and other people print off of it etc. and I was wondering if anyone knew why this happens.

New MacBook Air...internal speakers work fine. Have Bose speakers that I just tested on my Dell laptop, so I know they work. When I plug them into the headphone jack I get no sound. Volume is up and mute is not on.Â

There is no sound coming out of my speakers- internal or external. This problem just recently happened (I didn't get my MacBook Pro with this problem). I have checked and double-checked the sound preferences. Nothing is muted or anything and the correct "device for output" is selected.

where the external speakers i am running through my Focusrite Saffire 6 USB interface have ceased producing any sound at all when linked in to the Macbook Pro . I have plugged them in elsewhere and they are working fine , so that is not the issue . Â
i had performed the software update on my Macbook pro to get OSX 10.9.3 . I have gone in to sound settings and made certain that both input and output are set to the Saffire interface . A signal is certainly coming through and sound can be recorded , so input is fine . I have also done this in both Garageband and Logic , to no avail . However this issue is effecting ALL sound in the sense that nothing is coming out at all from any source . No sound is coming out headphones when plugged in to the interface.Â
Thought it might be the interface but this literally happened as soon as i tried using my set up with the new OSX 10.9.3 software installed . Oh and i also get an error message whilst playing a track on garageband : "Error while trying to synchronize audio and midi...Sample rate 42212 recognized , check conflict between garage band and external device". Here's a reminder of gear used :Â
-Macbook Pro OSX 10.9.3
-Focusrite Saffire 6 USB Interface

I have a problem with the headphone jack of my macbook. When i plug in some headphones or external speakers, it wont get sound to them, just like the headphone jack isn't there and the sound come out from the macbook speakers. The only ones that seem to work are the ipod original ones, but not if insert them completely, they need to be strategically plug in, like half in and half out, and if i move it a bit more the sound goes back to the speakers again. Does anyone knows what this might be and how to fix it? I can't use the warranty, because the warranty time already passed.

The audio on my macbook suddenly stopped working. When I click on the audio adjuster, it won't even let me change the level (the little circle is white now, not blue).
But when I plug in headphones or an external speaker, everything works fine. I can once again adjust the audio and get sound
There was a red light eminating from the audio out jack for a while (last couple of days) but today, there is no longer a red light. Still no audio from the speakers.

I have owned my MacBook Pro since June 2010, and have always used a pair of independently powered (via adapter) external Dell speakers for audio output. Since upgrading to Lion about 1 month ago, I was having intermittent audio issues, which were resolved by re-starting my computer (not ideal but it worked). Today, the speakers just stopped working. The internal speakers work, but when I plug the externals into the headphone port, they don't produce sound. Earbuds in the same port also don't work (but the earbuds are good). The external speakers are being recognized by the sound panel in system preferences.

My external display (HP w2207) seems to conflict with my MacBook Pro (15 inch Retina display, early 2013) since I upgraded MacBook OS to 10.9.4.The external display works at initial boot of Mac but does not work after OS sleeps and I attempt to awaken, and while the external display is not waking, the Retina display flashes through different screen views, which only partially reflect my normal screen, or do not reflect my normal screen at all.Â

I searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.

I had audio coming out my external speakers.
Then I fiddled with both Soundflower and Audacity for some audio recording.
I have since then uninstalled both but I can't for the life of me figure out how to get audio coming out my external speakers again.
Everything is coming thru my imac speakers.
Apple>Sys Pref> Sound> give me no options to direct audio to external speakers.

While using Google Sketchup and several other prgrams concurrently my macbook air cpu heats up substantiall. I like keeping the air "open" to allow for maximum heat disipation but of course this keeps the air screen on while I only want to use my external monitor. Is the only way to turn of the air screen turning down the brightness and using the "Mirror Display" option or is there another setting which alows my to utilize only the external display while the screen is open on the air?

I have bought a set of external wireless speakers to listen to iTunes while outside. If I plug my iPod into the wireless transmitter jack they work great. The problem is getting the speakers to work using iTunes on my iMac. If I plug the wireless transmitter jack into the headphones socket of the iMac I get no sound.

I have Logitech Z4speakers which have worked just fine, but suddenly (after itunes 8.1.1 upgrade and 10.5.6 upgrade) they no longer show up in sys prefs. I see that this is not an unknown problem, but I can't find a solution anywhere!

Party tomorrow night. I can stream music from my Imac computer to Apple TV (attached to my hifi system).Â
I'd like to have the imac speakers (external speakers) playing at the same time as the applt TV speakers. Â Seems that's possible in itunes by simply selecting both speakers.... however....
There is a sync issue. Â
The Apple TV is probably 1/3 second out of sync with the imac. I'm going to hardwire the apple TV to the router (the Mac is already hardwired to a router) which should help.Â
I've tried wireless connection from Mac to router to Apple TV and it makes the delay worse. Seems I really need to somehow insert a delay the signal frmo the Mac to the Mac's external speakers.... Â
Is that even possible or am I wasting my time thinking about using both speaker systems concurrently?Â

Just set up a new Mac Pro (8-core) and plugged in my old M-Audio powered speakers (about 10yrs old but still going strong!). I use a mini-jack splitter cable that outputs stereo RCA to the speakers, plugged into the speaker port on the nMP. There is a constant, low hum coming out of one of the speakers; it sounds a little like CPU noise and it is NOT affected by volume settings from the Mac or the speaker knob. It's the right-side speaker which is unpowered, connected to the left unit via speaker wire (the left unit has the power switch and audio inputs and is not affected.)Â
I've tried moving the speaker wire up and away from power cables (two Dell monitors directly next to the speakers) but that doesn't work; it doesn't sound quite like a DC hum anyway though. The speakers aren't heavily shielded (they usually pick up interference from an iPhone placed too close) so maybe it's always going to be an issue. I used to have them plugged into a 2006 Mac Pro via an analog mixer which I've removed from the chain.

It started when I was using an external monitor. There is a white line in the center of my screen on the desktop wallpaper. However it does not show up on any other screen. It does not change when I change wallpapers. I has to be a software issue because it only affects the wallpaper. Enclosed a pic of the problem. White Macbook osx 10.6.2
