Audio jack problem. PRAM reset has only temporary efficacy

Audio will not play through 3.5mm audio jack output unless I reset the PRAM with an audio cable plugged in. If the cable is unplugged, even for a second, then the sound output reverts to the internal speakers and I have to reset the PRAM settings once again.

Audio Jack Problems

Hello everyone, I have a 5th generation iPod that has a bad audio jack, are there any quick fixes for this? The audio works fine in the left ear but does not in the right, if i put heavy pressure on the male 3.5mm connector to an angle then it works but while left alone it will not work with both ears. I have owned the iPod for a long time but the audio jack dying happened a few weeks off warranty and I was quoted an obscene price for a repair. I had initially gone through 2 ipod videos while on warranty. For $250.00 I would expect much higher durability during this products short life. I have bought mp3 players for easily half that price and has lasted twice as long.
I am just so disappointed in my iPod it isn't even funny. To me, this isn't just buying an mp3 player, it's an investment, it's a product that will become a major part in my life. After this died, I ended up getting a 4gb nano and the same thing just happened to me today. I have taken good care of both iPods, keeping them out of extreme heat or cold, areas that could contain high amounts of ESD for fear of having a reaction because of the metal backing on the product. I don't know if I am ever going to be able to put any faith in an apple product again after having FOUR iPods with problems.

Unfortunately, it appears to a bad audio jack as you have determined. It will need to be replaced. Either you can purchase it [HERE|http://www.ipodparts.com/ipodpartscenter5g.htm] or from several other sites on the internet and then install it yourself using the instructions shown [HERE|http://www.ifixit.com/Guide/Repair/Installing-iPod-5th-Generation-Video-Headpho ne-Jack-Hold-Switch/604/1].
The other option is to send your iPod out for service to a site like [*_THIS ONE*|http://www.missionrepair.com/Mission_Repair_1st_Gen_iPod_Video_Diagnosiss/275.htm].
I recommend the latter option unless you are confident that you can do the repair yourself.

IPhone 5 audio jack problems

My iPhone 5 audio jack seems like it's broken or something. Every time I put my headphones in and I move them a little bit the music either pauses, changes into a different volume , only plays on one side ,or sounds like static. Is is broken? If so can it be fixed? Also it isn't the earbuds since it did the same thing when I use a brand new pair!

Bring your phone to Apple for evaluation. If defective, it will be replaced (free of charge if within the warranty period)

HP m7160n front audio jack problem

I am running Vista Home on my m7160n Media Center PC. I used to be able to plug in my headphones to the front audio jack and it would cut out the rear speaker output. Now it doesn't! I have gone into sound properties and is IS set to turn off rear jack, when the system detects a plug in the front jack. The headphones still work, but i need the speakers off when using the headphones. I hope thats enough information.
This question was solved.

Hi MrBassMan26,
That is odd and sounds like the jack-detect isn't working right. Did this issue just start happening? Did it occur after installing anything, even a Windows Update?
If it just started happening, you could try running a Windows System Restore to an earlier point when it worked properly. Or you could trying re-installing the sound driver or even installing an updated sound driver. That should take care of it, and if it doesn't you may need to make some configuration changes in one of the Sound properties (Windows or Realtek).
I see that you have Vista, did you by chance upgrade to Vista from XP?
Try installing the Vista sound driver from Realtek: http://www.realtek.com.tw/downloads/downloadsCheck.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&Down...
Let us know how it goes.

Yes but there's no point doing it here. As the Terms of Use make quite clear this is a User to User forum. It's Users like you talking to other Users. It's not a channel to communicate with Apple.

Yoga 2 Pro audio jack problem

Greetings,
Please know that I am not tech-savvy....at all! I have been researching this prpblem for about a week, and did find some posts here that are similar to my problem but the 'fix' didn't work I have owned my new Yoga 2 Pro 64 bit with Windows 8.1 (which I am not really enamored with) for two months. All was working fine until last week. I had been using the headset which had not given me any problems. But when, the next day, I plugged a larger speaker into the audiojack, as I'd done before with no problems, no sound came out. I realized that it was my laptop and not the speaker or the cable, and the speakers in the computer were workig fine.
Yesterday I plugged the headset jack in just to see if it would work, and suddenly it did--as did the larger speaker I plugged this Yoga 2 into. But there is no sound at all if there is nothing plugged into it, i.e. no headset or external speakers are plugged in and when I play something with sound, there is none.
Additionally, the screen warning comes on and goes off at random times, stating that I just unplugged an audio device, or that I just plugged in an audio device--neither of which I did at all..
What to do? I ran the test where I clicked on device manager, sound game etc, realtech etc, and it sai the driver is the correct one and does not need to be updated.
Thank you.
Judi

Two computers to one external hard drive problem, pram reset...

I have a Powerbook 15" 1.0 Ghz and recently I made the mistake of connecting one external hard drive to two computers. My OWC External hard drive was connected to my powerbook via firewire 800 and my PC via firewire 400 with both on. There is a tiny little blurb on the external hard drive's instructions that says do not connect to more than one computer at a time but of course I didn't see that until after the fact. My powerbook was painfully slow so I restarted but it wouldn't come back on. I was instructed to reset the pram, which I succesfully did but now the powerbook is so slow it is unuseable. The pc works fine. Did I do any permanent damage? Do I need to reinstall OSX or what? I will kill myself if I fried something on my powerbook. Please help!!

Disconnect all devices from your PowerBook as well as power and the battery for about 30 seconds. Put the battery and power back in/on and then reset both PRAM (3 consecutive times) and the PMU. Hopefull this'll bring it back to life.
Otherwise, create a new user account and see if things are better there. It is possible that you have damaged software rather than hardware so a clean instal may do the trick.

Speaker/headphone/audio jack problem

I've recently been having a problem with my headphones. The computer recognizes that I've plugged them in but it still uses the external speakers and there's no sound coming through the headphones. I've tried more than one pair of headphones and it still doesn't work. Restarting the computer worked once but not anymore.

Hi, there.
Newly purchased refurbished T430 Thinkpad with Windows 8.
Listening to music, I plugged in my headphones, everything worked just fine.
Unplugged the headphones to use on another device. Computer speakers worked fine continuing to play the music. So far so good.
But then when I went to plug the headphones back in, the computer did not switch to using the headphones to provide the sound. Just the main speakers.
The headphones make a chirping sound when plugged in (indicating the computer is recognizing the headphones).
The sound device area of the control panel indicates the headphones are working normally, but I can get no other sound from them except the "plug-in" sound.
Assistance is welcome.
EDIT: Oh, now the headphones work, but the computer speakers do not. No consistency as to which (headphone or speaker) is going to work and when; which is frustrating.

Migrated to ML from OS/X 10.6.8 on an iMAC 24'' (2009). Now system starts up in verbose mode and holds on the root(!) prompt. PRAM reset doesn't solve the problem

This is really buggy, because anybody could enter the system as "root" after switching on the system.
A PRAM reset works only for the actual boot; after a cold start the system holds again on root prompt.

If you've tried everything else there's always the SMC reset:

Laptop HP 14d-006La has only one audio jack (mic/headset)

Laptop HP 14d-006La has only one audio jack (mic/headset)
How can I solve this?
I need to use my headset built-in mic instead of the laptop intengrated mic but it has only 1 audio jack, Can I solve this by software? or at least can I choose wether use the jack as mic or use it as external speaker?
Thanks in advance for any help

Hi EdgarNaranjo,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP 14-d006la Notebook and having issues with connecting a microphone. Audio-out (headphone)/Audio-in (microphone) jack connects optional powered stereo speakers, headphones, earbuds, a headset, or a television audio cable. Also connects an optional headset microphone. This jack does not support optional microphone-only devices. Be sure that the device cable has a 4-conductor, a connector that supports both audio-out (headphone) and audio-in (microphone). Here is a document on connecting a microphone.
Hope this helps.
Thanks.

I was wondering where i can buy that spare part here in Saudi Arabia particularly in Jubail and if also apple has a service center here...
Thanks and Best Regards,

There are no legitimate sources for iPhone parts anywhere. Apple does not sell parts.

Help with BBOD! Can't seem to get to the bottom of it. Have tried SMC reset, PRAM reset, reinstall of Mavericks, Carbon copy clone, checked my CPU, Memory is 500GB and I'm only using 250GB thereabouts.

Here's what I've tried;
SMC reset
Pram reset
Looked at activity monitor - mostly seems OK aside from a kernel task taking up memory (approx 460MB) but CPU is around 96% idle.
Fan seems to be running constantly - heats up noticeably when I close the MBP
Despite a re-install of Mavericks, MBP is running frustratingly slow. Just typing is enough to bring on the beach ball.
Have backed up everything, reinstalled from a clone, checked through Apple Hardware test and carried out a Verify Disk Permission - nothing was reported, erased the drive and set up again - problem still stands.
Memory is running at 3.43 GB without anything really running bar Safari.
A little loath to install SMC fan control without knowing what's wrong.
Checked software updates.
Can anyone tell me what the matter is? Does this have a fix?
Have been reading up various posts but to no avail so have resorted to posting myself.
Does this sound familiar to anyone?
Many, many thanks
Roque

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
