MacBook :: Why Will The Volume Only Work If Headphones Are Plugged In

Mar 26, 2012

The volume for my MacBook will only work if my headphones are plugged in. I've tried just about everything I could think of to fix the problem but it's still not working. I've tried blowing it out, wiggling the headphone jack, checking the sound settings from the system preferences. I've come to the conclusion that there is a problem with the sensor, but I wanted to find out if there is anything else I could try before taking it somewhere to get repaired.

MacBook Pro :: Lost Volume Control When Headphones Are Plugged In?

May 19, 2012

When I first bought my MBP (January 2012) I had this problem; plug in headphones, and I lose the ability to control the volume using the keyboard controls.Over the phone, Apple had me do a PRAM reset. After that it only happened sometimes, with a regular reboot solving the problem. It happened again today. I did a PRAM reset again because I'm sick to death of the little ******** issues I have with this MBP. (I've brought it into an Apple store, they kept it for a week and said nothing was wrong with it.)  

The PRAM reset got it working ... then I plugged in the headphones. They still worked while they were plugged in, but when I unplugged them. Gone.BUT, not only are they gone for the MBP's speakers, they're gone for the headphone as well this time. AND, not only are the keyboard volume controls not working now, but the little volume slider at the top of my desktop isn't working either. I did a regular roboot, it solved it, until I plugged in my headphones.  But it gets better, the keyboard buttons work if I'm using my headphones and listening to something on YouTube, but they don't work if I'm listening to iTunes. And that's only the headphones, MBP speakers non-responsive in either case. 

I do get the little pop-up interface that shows you the volume going up and down or if it's muted, it even gives me that little chime everytime I click the buttons, it's just not doing anything except looking pretty. I can control the volume either by using the volume slider in iTunes (or whatever application), as well as by going to System Prefrences, clicking on Sounds, and controlling it using the Output Volume slider.

MacBook Pro :: Why Won't Audio Work With Headphones Plugged In

Mar 8, 2012

I've had my mac for a couple months short of a year. A few weeks ago, I needed to record a quick idea for a melody my guitarist and I had. I was aware that the I/O jack were one and the same in the 2011 MBP model, so I changed my settings to allow me to use it as an input jack. No problem.The problem, though, is that I can't use it as an output jack anymore. Audio plays fine through the built in speakers but turns into static when I change the I/O setting to output and plug my headphones in.

MacBook Pro :: Volume Control Only Works With Headphones?

Feb 13, 2010

When my headphones are plugged in I can use the volume control keys on the keyboard to adjust the volume just fine. But when I unplug my headphones the volume display goes dim, my volume control keys no longer work, and my speakers will not play sound.

The problem started last week. The computer has never been dropped and I won't even bring liquid near it so I know neither of those caused this.

Has anyone else had this problem?

MacBook Pro :: Setting Initial Volume Level For Headphones?

Jul 9, 2010

The volume level for the built-in speakers is remembered across boots, but it is not remembered for headphones.

I.e. Whenever I plug in the headphones after a boot, the volume level sets itself to 50% - too loud for my ears and possibly damaging to the headphones.

Anybody know of a way to change this behavior? - To set an initial volume level for headphones?

I have OSX 10.5.6.

IMac :: Headphones Plugged In But Not Detected

Jan 21, 2009

I have a ~year old 24" iMac (2.8 GHz Core 2 Duo) that I just suddenly started having a problem with. I use headphones pretty regularly and they are almost always plugged into the headphone jack. Recently, I lent my headphones to someone and, when I plugged them back in, the machine doesn't detect them. The audio works just fine coming out of the internal speakers, it's just that it *always* comes out of the internal speakers, no matter if the headphones are plugged in or not.

I took a look at the Sound Preferences panel and, sure enough, it doesn't detect the headphones as plugged in (just the internal speakers). Does anyone have any suggestions on troubleshooting? I'm not sure it matters, but I did just recently upgraded to 10.5.6. The headphones worked after the upgrade, but it may be that this is the first time they were *re*plugged in after the upgrade.

Jan 7, 2010

I've recently started using headphones more and more and something that really bothers me is that I can't change the output source to the Mac's speakers unless I unplug the headphones entirely. Is there a way to do this without unplugging the headphones? I've looked through Audio MIDI Setup Utility as well as the Sound system preferences but found nothing.

OS X :: Macbook Wireless Doesn't Work When External Display Is Plugged In?

Nov 11, 2008

I have a white plastic macbook which appears not to be able to connect to my wireless network. All the other PCs and a Mac Mini in the house connect fine, but the macbook does not.It has connected since i got it, both to the home network and a network in school, but today it promted me for the wireless password, connected a few times but did not give me a IP address, and now will not connect at all! The network appears in the list, i click on it, enter the wireless password, then it says connecting before connection failed.

The network setup is a Cisco router connected to the modem and then connected to the wireless too. There are no computers connected via cable to the network.

MacBook Pro :: Microphone Will Not Work When Plugged Directly Into Line-in Jack

Jan 31, 2012

I am trying to get a Sony ECM-DS70P Condenser Stereo Microphone with a 3.5mm stereo male plug to work on my MacBook Pro with a Behringer UCA222 USB Audio Interface and I am having no joy at all.The Microphone will not work when plugged directly into the Line-in jack on the MacBook Pro because the Audio Line-In input on the MacBook is line level -10dB to+4dB and microphones are generally around -40dB. So, I need either a line level preamp or a usb audio interface.I decided on a USB Audio Interface (Behringer UCA222).The Microphone is plugged into a 3.5mm stereo to RCA L & R cable which is plugged into the L/R RCA inputs on the Behringer UCA222. The Behringer UCA222's USB Cable is plugged into a USB port on the MacBook Pro.

On the Macbook Pro in System Preferences > Sound > the output is set to Internal Speakers and the input is set to the USB Codec (Which showed up when the Behringer UCA222 was plugged in). [code]

MacBook Pro :: Won't Find Battery Life Info / Plugged Or Not Plugged

Oct 17, 2009

I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.

I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.

MacBook Pro :: The Sound Doesn't Work - Volume Is Muted And Can't Unmute

Nov 30, 2009

The volume is muted, but I can't un-mute it because I am unable to click on any of the sound options because they are all "grayed out". The little box next to mute is checked and I cannot un-check it because it's grayed out. Nothing works when I plug in headphones or speakers or anything, and there is no red light glowing where you plug the headphones or speakers in.

OS X :: Flash Drive Will Not Work When Plugged Into PC

Oct 6, 2009

I have/had a 16 GB Kingston Data Traveler flash drive with all of my work files on it. I travel a lot for work and I was just in Italy for 2 weeks. Anyway, I went to an internet cafe to print a document before a meeting. 20 minutes before I went to this place the drive worked fine. I got to the place, and it seemed to me that the guy didn't know what he was doing. He had machines running on XP and they were extremely slow, and he just kept clicking away. He finally turned to me and said that his machine wouldn't read my drive. I blanched and tried putting it back into my Macbook and felt sick when I saw that the drive was no longer recognizable on my Mac either.

I had backed up almost everything on the server before I left for Italy, and I had emailed most of the new documents I had created while away from the office. Unluckily, there was one folder of documents that I hadn't backed up on the server because there wasn't enough space there (grrr), so I had left them on the drive. A few lessons I learned:
-back up on the desktop or hard drive as well while traveling
-bring the portable printer next time
-don't let someone mess with my jump drive

Should I reformat the drive and attempt to use it again, or should I buy a new one that is a better brand? I definitely don't want a repeat of this. This is the first time I've ever had a problem like this--all the other drives I've ever used, from expensive to cheapies, all worked fine. Is there any way to recover any of these files or should I just accept that they're gone? My guess that being an internet cafe with PCs, the computers were full of viruses and the drive became infected corrupted. When I try to repair it or verify it, I get an error message.

MacBook Pro :: Display Won't Work Without A Second Display Plugged In?

Mar 31, 2012

I'm using a Dynex Mini DisplayPort to DVI Adaptor to use a second display (an older display, I'll admit). After I have unplugged the adaptor, my MacBook still tries to read the second display, and switches back-and-forth between a blue screen & my desktop. It stabilizes once I plug the adaptor back in. What is causing this problem, and how do I fix it so I can use my primary display without having the adaptor constantly plugged in?

So I clicked the volume up button, and it doesn't change the level (there's a small "no" sign, the circle with the line through it, under where the volume level should be). In the menu bar, the volume control is now a light grey and I can't use it. Same with in system preferences. Any ideas on how to get volume to start working again or why it stopped?
