Intel Mac :: External Speaker Port Not Working?

May 11, 2012

I have a pare of powered KRK Rokit speakers which I connect to my iMac via the headphone port. Never had a problem with this connection, but today the port doesn't seem to be working. 

In normal circumstances, as soon as I plug the speaker cable in the port, the internal speaker of the Mac would disabled itself (even if the KRKs are not powered). However, now I plug the cable it and the internal Mac speaker keeps running. It seems as if the port does not recognise that there is an external source connected.

iMac, Mac OS X (10.7.3)

IMac :: External Speaker Sound Only Coming Out Of One Speaker?

Dec 21, 2009

I have a 2.1 Logitech Z4 setup, and the sound is only coming out of the left speaker. I have checked the wires, they are fine, and both speakers do work - but it could be the socket that's the problem. It's plugged into the line-in socket, I have put the output in System Preferences to Headphones, and everything is inserted correctly.

What do I do?

EDIT: My sound system is plugged into the headphones jack. I have tried putting headphones into the headphone jack and the sound also only comes out of the left earbud.

OS X :: External Monitor / Mini Display Port Stopped Working On MBP?

Jul 1, 2009

I have a 15" unibody MBP bought in Nov '08.

Had been using the Mini Displayport > DVI adapter just fine with both HDTV and Dell monitor, BUT then all output has stopped completely!

No monitor is detected by the laptop (although the display does blink blue, as if it had detected it), tried different cables, different displays, using the Displayport firmware update, speaking to Apple, deleting the com.apple..plist files, etc

Edit: it also doesn't work in XP on Bootcamp

Intel Mac :: Firewire 800 Port Not Working?

Feb 28, 2012

It WAS working. I'd bought an iomega fw drive with usb and fw800 ports.  I hooked up the drive and it worked and then suddenly I got the message that a drive had been ejected improperly. The fw800 port never worked again -- with any drive or any cable. My apple care has run out.  (I've tried these cables and drives on another computer.

Intel Mac :: Use Firewire 800 Port To Connect To External Hard-drive Using A USB Micro-B Input?

Jun 9, 2012

I have a late 2009 iMac with Firewire 800 input on the back.  I have a Western Digital Passport external hard drive with USB Micro-B input that I would like to connect to the Firewire (4 USB inputs aren't nearly enough on the iMac). I can't find an adapter to do this. As an alternative, is there an adapter that will convert the Firewire 800 to standard USB2.0?

MacBook Pro :: One Speaker Not Working For Certain Programs?

Dec 3, 2014

When I either receive or place a FaceTime call on my MacBook Pro, the left speaker cuts out audio and produces high static.  The right speaker is fine.  The receiving end can also hear the static feedback, but their two speakers work fine.  I have all my iOS devices setup to receive and place FaceTime calls (iPhone 5s, iPad, and MacBook Pro 15 inch late 2011).  If I place or receive the FaceTime calls on my iPhone or iPad, there is no problem.   I've tested the speakers, youtube, iTunes audio, streaming websites, netflix, etc... and all works fine on the MacBook Pro.  Just FaceTime.  I also went into system preferences and the speaker setup is correct (audio in and out - internal speakers). I've also restarted, reinstalled Yosemite...still FaceTime left speaker problem.

MacBook Pro :: Speaker - Volume Controll Not Working

Aug 9, 2009

I just got the new 15" Macbook Pro a few days ago. My first Mac

Anyway, when I plugged my external speakers into the headphone jack of the MBP, the volume control (both in the Apple bar thing on the top of the screen and the F10/F11 buttons) switched so it would control the external speakers, as it should. The problem started when I unplugged the speakers and went to use the internal speakers again.

And the volume control doesn't work. If I push F11 for volume up, the little screen appears and it looks like the volume is going up, complete with the little water drop sounds, but it doesn't actually adjust the volume. If I plug the speakers back in, it will control the speakers properly, but I can't figure out how to make it control the internal speakers again

I'm sure that if I restarted it would fix itself (probably), but that's a real pain as I am frequently plugging in and unplugging speakers to my laptop.

I have a 15 inch Early 2011 MacBook Pro w 16GB RAM

Hardware :: External Speaker System For New IMac

Nov 5, 2010

A few months ago I bought :
iMac 27"
2.8 GHz Quad Core i7
8GB DDR3 SDRAM 2x4
2TB Serial ATA Drive
ATI Radeon HD 4850

Actually, still moving into it from the old one, haven't spent allot of time on it, hard to get out of the old one with my photoshop work. Anyhow, whats a good external speaker system for it? I find myself with the volume maxed out on the internal iMac speakers now, don't think it's too good to keep doing that. Is the amp in the iMac my only control over volume? Can I buy a speaker system of very good quality that may have amps within them so I can get more volume to them? I have a real top end stand alone stereo system, but doubt the iMac iTunes can be run through that.

OS X V10.7 Lion :: External Bluetooth Speaker Volume Too Low?

Jun 14, 2012

I have an external bluetooth speaker from jawbone called jambox. From the start on I had the normal speaker volume like I also stil have it if I connected the bluetooth speaker with my iPod touch. But some day ago, the volume from my whole Mac (not just from iTunes) dropped through my Jawbone. It is not just about 40% of that, what I know of, that the Jawbone Jambox is able to bring. This problem exists through all audio / video programs on my Macbook Pro. So like in iTunes, also in VLC or MplayerX. Everywhere. The software sound of MacOS Lion is on maximum. Also the sound control of the jambox itself is reached. It seems like there is a protection against to high volume anywhere turned on which just do not allow me to turn up the volume beyond a specifc point of db. But, I can only repeat: The speaker is in a good shape. I am able to play music much more louder with my iPod paired. But just not with my macbook. I am looking for a "hidden" option to disable the maximum volume limitation of my Mac to the speaker.

MacBook Pro :: External Speaker Buzz When Charger Plugged In

Apr 19, 2009

I've noticed a faint buzzing sound through my external speakers when a charger is plugged in to the laptop. Removing the charge kills the noise and makes the sound crystal clear again. Doesn't bother me to much, but as my uni-macbook pro is plugged in most of the time I can see this near constant buzz getting on my nerves a bit in the future. Any ideas, looking back I experienced the same thing with my macbook.

IMac (Intel) :: External CD / DVD RW Not Working On Older One

Jun 21, 2014

The SuperDrive in a oldish iMac ca 2007 (Intel Core 2 Dual Processor Speed: 2.4 GHz; Mac OS 10.6.8) refuses to allow me to burn DVD's all of a sudden; the disc just gets rejected.  Used to work fine.

Anyway, I've a new external drive which I use with a MacBookAir but this doesn't seem to work on the iMac.  No power to it.. zilch.  Works OK on the MBA, etc.Am I right in assuming there's no way the external drive will work with older Macs?

Intel Mac :: 21.5" Speaker Damage Due To Feedback?

May 1, 2012

I transferred some Garageband files from my old iMac to my new one. I opened up a song to listen (it had been about 4 months) to it and I forgot that the monitor was on. I am assuming that feedback protection was on, as there was nasty and extremely loud feedback for about 2.5 seconds before the "feedback detected" message popped up. The volume on the Mac was at between 60 and 75 percent up. 

I am slightly concerned about damage to the speakers. Everything sounds ok, but I noticed a slight tinny, feedback sound (on the highs) on certain songs. It could have easily just been part of the songs I listened to, as some were self-recordings of not great quality. Others (acoustic) did not seem to have that problem. 

I understand feedback can be dangerous, but the fact that Garageband caught it fairly quickly, there was no pop or buzz, and I still have working speakers makes me feel a bit better. In short: am I just being paranoid, or does this warrant a trip to the Apple Store to have them take a look?
