IPod Line Out Problem

I have my iPod connected to my car stereo to play music via the line out signals. It is powered / charged via USB connections on pins 23 (USB power), 16 (USB Ground), 25 (USB Data -) and 27 (USB Data +). It sends line out audio to my stereo via pins 2 (Common), 3 (Line Out Audio Right), 4 (Line Out Audio Left). Pin 11 is connected to Pins 15 and 16 to send the audio to Line Out rather than the onboard speakers. Pin 21 is connected to Pin 15 and 16 via a 68K ohm resistor to avoid error messages. When docked the charging works correctly but the audio signal will switch between Line Out and the onboard speakers. It will start by sending music via Line Out but after 20 seconds it may switch to the onboard speakers. After another 20 seconds it may switch back to Line Out or it may continue to play via the onboard speakers. Eventually it will usually switch back to Line Out but it may take a long time. The fact that it repeatably switches back and forth after 20 seconds is interesting. It's like it is checking to see what mode it is in and it's not seeing what it should see. I've checked and reworked all of my connections several times. I still can't eliminate this problem. Any idea how to correct this? I would really appreciate some help!

EDIT: I just tried headphones instead of my home dock and had the same problem...is my headphone jack bad?

Macbook pro 13' 2010 line out problem

My problem is:
When i use the line out on my Macbook pro (13' 2010), before the sound or music start i hear a "click" (or pop, i don't know how to call) noise on the headphones (or a connected speaker).
If i stop playing, and after a while (about 20 seconds), i hear a "click" again.
I think this is because it turns on and off the line out port on the macbook. (turn on the line out when i start to play, and turn off when i stop to play).
This is normal? This is irritating me, because it's annoying.
Is there a fix for this?
Please help me.

I just tried it on my wifes 13" and it does have a slight pop, very low in level at the beginning of a track, and while in pause. I did a pram reset and it seemed to reduce hoe often it happens, especially in pause mode and it now seems to not do it on every song. It was VERY low in level and has not popped at all in pause while I typed this response. It might be a part of Apple cheaping out the audio section on the 13', I have a 15" and never had this issue. She never mentioned it to me, but she usuallly listens to her music very quiet. Still no pops, where as before the pram reset there was one about every 1/2 minute or so in pause mode. You might want to give it a try and see if it helps. But it still does it at the start of the first song but I did not here it going into the next. Pram reset: disconnect all peripherals, power offthe MBP,power it back on and hold the following keys. Option,comand,P,R(no commas) Press these keys before the start chime and continue to hold them till you hear the start chime 3 times then release. Maybe it will help. All the best

AUDIO Line Out Problem

Something weird happened today. I had the audio from my 2.1 system plugged into an iogear DVI switcher. I no longer need the switch anymore, so I then plugged the audio cable from my 2.1 system directly into the audio in port on the back of my Mac Pro. And I get no sound. I tried everything I can think of. The "line out" option is selected under the "Sound" in preferences. I tried plugging in headphones to the headphone jack and get no sound either. When I change it to "internal speakers", I do hear the sound. Just for the heck of it, I also plugged the 2.1 audio cable to the front headphone jack and still no audio from the speakers.
I am pulling my hair out here...can anyone offer any advice??
THANKS SO MUCH!

OMG, I'm so stupid!
I had plugged in my iPhone earlier to the Aux input of the speaker control on the desk and left the plug adapter in it! When it's plugged in, it doesn't allow anything to come through except the Iphone. Unplugged it and all is well again. I can't believe I didn't figure that out on my own earlier!!
Well I hope this helps someone else out in the future who makes this same stupid mistake!

Ipod line out volume far too low

Sorry if this has been dealt with many times before but why is the volume limit so low on the headphone jack on the iPod 120GB classic? It makes it vidtually impossible to hear music with a lot of dynamic range and you might as well forget about listening to any Classical music outside of a sound-proofed room.
I also want to connect the iPod to my HiFi and Car Stereo via the jack but I have to turn the HiFi so far up to get any volume that distortions etc. become apparent. Again, it makes a £179 purchase pretty pointless for the use I have of the player. I wish I had noticed the limitations before the 14 day statutory rights return policy expired. Can this be resolved by firmware upgrade or is the iPod destined to eBay??

Hi Syex,
I'm sorry about your negative experience with this volume issue in Firefox OS, as well as the update time for your your ZTE Open C.
I understand your frustration about the volume, and this is something that I also experience regularly when connecting my device to an external source. You have my complete empathy on this, and I will continue to push for investigation and a resolution of this issue.
I also understand that you are experiencing a long time for the download of updates on your device. ZTE is responsible for releasing updates, including hosting the update files. This slow download speed may be caused by a slowness on their servers. This is the first time that I hear of this issue, but I will forward this report to our Technical Account Managers if I see other reports around update speeds for ZTE.
Regarding the [http://firefoxosbuilds.org/install/] page, it was created and maintained by the community of Mozilla contributors. Since this is an unofficial update process that can brick the devices, it's recommended that only advanced users attempt it. If you have Windows, you should also be able to just double-click the '''flash_windows.bat''' file inside the Unzipped folder.
Here is a Youtube video I just found with instructions of how to open a Terminal on Windows, as well as simple basic commands, in case double-clicking the '''flash_windows.bat''' does not work:

Again, I'm sorry about your negative experience with Firefox OS. We will continue to fight for an Open Web and to improve the system, and hopefully you will give us another try in the future.
Thanks,

MOVED: Exasperating Realtek line out problem

This topic has been moved to MSI Notebook.
https://forum-en.msi.com/index.php?topic=138403.0

OK, here's a new development. When I plugged headphones in for the first time recently I saw this pop up saying an audio connection had been made. That inspired me to plug and unplug the audio out in the back a couple of times until the same message appeared again. I then had audio to my desk top speakers. That lasted for about a week. Then today back to no desk top speakers and internal audio only. I plugged and unplugged the rear out jack a few times to no avail. Just a reminder, I have not had trouble getting audio out on the Mac side, just the bootcamp side. Also, I would describe the output jack as a little loose. Any ideas?

Line out and headphone problems

Just recently I have started to have a problem where if I use the line-out funtion of my iPod audio will not come out of the headphones afterwards. I use the Belkin auto-kit so I just connect my iPod whenever I drive somewhere, and it annoys me that I have to reset my iPod every time I want to listen through my headphones. I have tried unplugging and plugging back in, increasing and decreasing the volume, pausing/resuming, and changing songs but to no avail. The only solution is resetting the iPod. I was just wondering if anyone out there has had this problem, or knew if there was a more practical solution than just resetting the iPod every time.
5g iPod 30GB Windows XP Pro

Went to the genius bar earlier today to have my Mac Pro looked at. They said that front board and backplane failure is fairly common. In fact, the genius mentioned that his own 12-core suffered the same issues insofar as audio crackling and eventual analog out failure.
I should be getting it back in 5-7 days.

Ipod 1.2.1 Line Out

I updated iPod with the new software, the line out from my dock doesn't work anymore. I can hear music, but it is very quiet and the volume doesn't work for it. On the go it is fine but i use the dock to connect the iPod to my stereo. I just want to go back a version but it seems I am not allowed. I don't know where to find 1.2.0 or what ever it is. I tried to go to 1.1.2 but it told me I couldn't because there was a newer version. Could someone please provide a real answer to how i could either fix this problem or go back a version?

That is strange. I have the ipod connected with a third party wall adapter and the dock and now it works. I don't know. I barely use the usb adapter anyway so i guess this is good enough.

"Line-out" volume problem?

I seem to have a problem with my 2nd Gen Nano's "line-out" volume. I have purchased 3 different FM transmitters to use in my car, and with each one, the volume is so low that it is almost unuseable. So, I bought a $100 direct connect interface so that I can connect the Ipod directly to a "docking cable" that is connected to the back of my car stereo Head Unit (through a little device). Still, the volume is just way too low, even at max volume of the car stereo.
Any ideas?

I'm assuming the JB3 works in the same way as my JB, which may or may not be correct.
I have never seen the message you refer to but there are 2 line-out sockets at the back of the player and a headphone socket at the side. The headphone socket has variable volume but the volume controls only work when headphones are plugged in.
The line-outs default to a fixed ouptut level - that is what line-outs are, a standard level of output for feeding into an amplifier. In the menus, though, you can set them to variable output so that they work the same as the headphone socket. Again you need something plugged in to the socket you want to adjust the volume on.
To switch to variable volume press Lib and go to Personalization, Line Out and change the setting.

Is the iPhone4 dock line out dif from iPods?

My SendStation dock connector, which works on iPods, exhibits no audio from the line out connector
when connected to my new iPhone4.
Just in case, I made sure that the USB connector is also connected.
Still no audio.
Headphone connector works.
Google does show a few people having very low line out audio level problem.
No answers yet.
I'm hoping it's a setting.
Thanks.

When I bought my first iPod (a 40GB hard drive based model) it came wth a dock. have used that dock over the years as I upgraded to a 5th Gen iPod, then a first gen iPod Touch, an iPhone 3G, a 3rd Gen iPod Touch, and now an iPhone 4. All my devices seem to work about the same in that very old dock. Only the hard drive based devices fit it properly, but the other devices stll plug n (with plenty of free space around them) and play just fine.
Based on my experiences, I wold guess that it's either your Sendstation or your iPhone that is the problem but based on what you provide it is hard to determine whch. If ou have any friends with iPhone 4's you could ask them to try their phones in your dock. If theirs works fine, it is probably your Phone, otherwise if theirs have problems too I would suspect you have a faulty dock.

IPod Universal Dock - line out?

Does the Universal dock provide line-out audio, or is it variable audio only? If only variable, can I use an older iPod photo dock with my 60 GB iPod w/video? That one has line-out, doesn't it?

Hey, I used my old dock and connected the line-out and s-video with my new 5G and everything works fine.

IPod nano - mini jack Line out not working anymore

IPod Nano Grey Out Problem in iTunes??

I purchased my iPod Shuffle last year. I installed iTunes in my Window PC and purchased music via the music store.
A month ago, I purchased a iPod Nano, I added the iPod Nano to iTunes. iTunes will update my iPod Nano automatically when I connect it to my computer.
However, all the songs in my iPod Nano menu in iTunes appear 'grey out'. I can't do anything like delete, play them etc??
Can anybody advise me how to solve this 'grey out' problem?
Thanks,
Jacky

Welcome to Apple Discussions!
If you update automatically, the songs are grayed out, because the songs should be on your computer.
To delete songs, you can uncheck the songs/podcasts you don't want on your iPod in iTunes. Then connect your iPod to the computer. When it appears in iTunes, go to edit-->preferences. Click the iPod tab, then the music tab under that. Check "Only Update Checked Songs" and click OK. Only checked songs will be put onto the iPod.
See this for more ideas/tips...
Deleting songs or playlists from your iPod
To be able to play songs on the iPod through the computer, delete songs only on the iPod (without having to check and uncheck), and to have songs not grayed out, you would have to manually update. Songs would no longer automatically update onto the iPod. You would have to drag new songs that you want on your iPod onto it (through iTunes)...

Line-out audio problems.

Can Apple please solve this: The line-out (and/or headphone-out, or default-out) on my 2010 Mac Pro just stops working on a daily basis. I use SoundFlower and LineIn apps as directed and they work fine on all internal sound-generating apps like iTunes, EyeTV HD, SoundStudio, etc. But audio coming in through the built-in audio line-in jack stops working at some point every day, or overnight. Sound control panel shows audio is getting into the computer, and LineIn app shows input and output, but I don't hear sound through the Mac's Line or headphone output.
The "fix" is to keep switching inputs, outputs, quit and relaunch both SoundFlower and LineIn apps and, eventually, sound will return to the line and headphone output jacks on the Mac Pro. ( Switching here means choosing on-screen options, not physically replugging, which I have tried also to no avail!)
As as active, professional composer/arranger, having to go through this ritual for 10 - 30 minutes every day before I can start working is becoming a major annoyance!
I have read posts elsewhere where users complain of this same problem (though more often on a MacBOOKPro than on a MacPro) and it almost seems like this is a bug is in the Mac OS since OS 10.4, but it has not yet been solved or otherwise addressed by Apple.
Can someone alert Apple to work on this, or has someone else found the cause and/or solution?
I have the latest versions of OS 10.7.5, SoundFlower and LineIn freshly (re)installed.
Rebooting does not solve the problem. Only the playing around with inputs/outputs I describe above.
I have run Disk Repair and the HD is fully verified OK and all permissions have been repaired and read as correct.
As I have said, I can get everything working just fine, then leave the computer for the evening, and when I try to return to work the next morning, the problem is back.
I leave the computer fully on (no sleep) and I shut the monitor off as opposed to putting it to sleep so, on paper, nothing should be resetting itself, yet it does.
Can anyone help?
Thank you.

SoundFlower is notorious for causing OSX problems. Not familiar with Lineln, but would search for anyone else having compatability issues with Lion if I were you.

Line-out audio signal of 6G (sixth generation) iPod Classic (120GB)

I suspect that the audio signal that comes out of the Dock Connector of the 6G (sixth generation) iPod Classic (120GB) is not a line-out. Because like the iPod Nano the 6G iPod Classic outputs a signal that can be made louder by turning up the volume from the click-wheel.
Is this true? Am I getting the same signal from the dock as what I have on the headphone port?
For music on the go this is not an issue but if the iPod is one of many sources going into your hi-fi amplifier the experience will be frustrating!
Thanks,
Swake

I have an iPod Classic 120GB and have just connected it to the dock that came with my old iPod Photo (using a piece of cardboard as a dock adapter because, for some reason, the dock design must have changed and the dock adapter that came with the classic won't fit).
I can state that changing the volume level on the iPod has NO effect on the volume coming from the line out of the dock. The line out volume is also much louder than the loudest volume I can get from the earphone socket.

Audio problems - soft sound, no line-out detected

ok, so a number of things went wrong with my computer.
it was working perfectly, and i opened garage band up to record music, and all of a sudden, no sound was coming out. at this stage i was using the line-out to my stereo amp. it also wouldnt let me change the volume and came up with the circle-with-a-line-through-it symbol.
i did all the standard stuff, close garage band, play with the settings, go into system pref. restarted it, and then it was making some strange fuzzy noises, and system pref. said that no audio devices were detected, so i restarted again. now i only have built-in output detected, and its very quiet, even on full volume, the volume and mute controls all work.
so thats all of my problems. im currently running OS X 10.4.10 on an intel-based iMac.
thanks

Folks,
on Nov. 29, 2007 we have begun shipping a revised PocketDock Line Out USB, which is now iPhone-enabled. We have also revised the 1/8" stereo plugs on the included cables, so they are now thin enough to fit the iPhone’s recessed headphone jack.
Note that not all retailers might have the newest stock, so if you want to be on the safe side, either ask for which revision they sell (the iPhone-option is mentioned on the packaging) or order directly from http://www.sendstation.com.
Best regards,
André Klein
