Nano Dock Line-Out isn't working

I just got a new Nano and Nano dock....when trying to connect it to my home stereo with the dock and lin-out connector (using a mini to dual RCA jack adapter), I get absolutely nothing on the stereo. The dock is plugged into the wall with a USB power adapter and shows charging so there is power to the dock.
Other devices into the stero work on those inputs so it is working fine. Are there some option settings somewhere that I have to enable to get the the Nano to enable that line out port on the dock?

I think I have figured out what is happening.
I had the same problem, and couldn't understand why the supposedly fixed line level was so extremely low suddenly.
As it turns out it is possible to change the volume of the line out signal using the normal volume control even when the nano is in the dock!
When the nano is placed in the dock the volume is pre-set to the correct one, BUT if you manually turn the volume up to maximum level, then the line out signal is muted!
I guess the volume should really be fixed, or at least not adjustable via the normal wheel, when the nano is in the dock. Why max level mutes line out is anybody's guess...
(I use the new universal dock.)

Universal Dock: Line Out isn't really Line Out!

I recently purchased a new Apple Universal dock for use with my Ipod touch. The goal as to access the line out port to hook up to my stereo (driving a stereo through the headphone jack is not the way to go)
I was led to believe that the Line Out capability of the Ipod touch bypasses the internal headphone amplifier, thereby solving all the problems inherent in using the headphone jack (i.e. impedance mismatch, volume too low, etc.)
Such is not the case. With the Universal dock's line out, the sound is exactly as crappy as through the headphone jack, and when I put the output on the scope, it was nowhere near the standard line-level voltage.
Any ideas as to what gives here? I suspect the Universal Dock is not really providing a line out at all....

The iTransport turns any currently available iPod player into a high-end media server by providing a bit-perfect digital audio output to an audio/video system, bypassing the player’s internal digital-to-analog conversion (DAC) and analog output stage. Subsequently, the audio signal remains clean and unadulterated throughout the path, outputting a “bit-perfect” digital stream. The iTransport is compatible with:
All Current iPods All iPod Nano Models The iPod Classic Models iPod Video Generation 5 Also the New iPod Touch/iPhone Models
To ensure compatibility, please make sure your iPod has received all software updates before docking it with the iTransport
“The Wadia iTransport is the coolest product I’ve encountered in some time. If you own an iPod and a high-end system, the iTransport is essential!”- Robert Harley, The Absolute Sound, November 2008
“The iTransport let me hear every detail as readily as did playing [a disc] on the [$6200] Simaudio SuperNova. If there was a difference between the original CD and the digital output of the iTransport, I never heard it!”
- Wes Phillips, Stereophile, Class-A Rating, October 2008
“This is a brilliant product! One that finally lets the iPod be all that it can and should be. It took the imagination and know-how of a firm like Wadia to pull this concept off. The real genius of the iTransport is that it lets you pull digital audio straight off the iPod and route them to a superior-sounding outboard DAC. You’ll have an audio player that not only rivals (but in some cases handily outperforms) multi-thousand-dollar music servers and CD players!”
- Chris Martens, Playback Magazine, August 2008
“Until now, there has been no real bridge between the convenience of an iPod and the high-end audio listening experience,” commented John W. Schaffer, President, Wadia Digital “The goal of making the player a true high-end media server has been hampered by the need to send the digital signal through a portable player’s D/A converter rather than that of a high performance audio system. We designed iTransport to bypass the player’s converter and output stage altogether. When used with an iTransport, theiPod becomes a digital music source equal to some of the finest sounding transports in the high-end audio market.”
Along with turning an iPod into a high-performance audio server, iTransport is one of the first docks to access video content stored on currently available iPods. Similar to the audio section, the video signal is made available via high performance component outputs that provide up to DVD-quality video.
The Wadia 170 iTransport measures 2” x 8” x 8” (H/W/D), making it an easy addition to most racks and entertainment centers. Wadia incorporates a bit-perfect S/PDIF digital output and high-resolution component digital video output, as well as analog audio and video outputs for easy connection with most audio/video systems. Your iPod will be charged while in the dock and the iTransport comes complete with a remote to control all iPod functions.
“I can tell you this much, it sounds fantastic! The dream of the iPod being a true audiophile component has now been realized and the sound quality is limited only by the DAC you own….the iPod through the 170 fooled a lot of people at my place into thinking they were listening to a five figure player!”

Installed Yosemite - audio line out no longer working

After installing Yosemite, sound will only play from my Mac Pro's internal speakers.
Opening Preferences > Sound and selecting Line Out has no effect.
Why does the Line Out no longer work with Yosemite?

Update:
Seems issue with keyboard volume not working crops up again each time the system enters "sleep" mode.
Volume controls will visually make the volume appear to adjust on screen, but not affect sound level to external speakers.
Only solution I've found so far is a reboot.
Never encountered this with Maverick's or any previous OS.

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.

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.
Mitch

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.

Eu volume cap on dock line out

This may have been answered before, but does anybody know for sure if the eu volume cap applies to the line out of the dock aswell as the headphone out?

Cheers Jeff,
I have the older 60gb iPod, but I don't believe goPod works with the latest firmware either. I have used goPod to try and uncap my iPod and although it says that it has uncapped, I noticed no difference in volume output. I even hooked my iPod up to my PC, then ran it through SoundForge to test the levels capped and uncapped and the results were identical.

Play your iPhone through speakers with dock line out

I discovered this nifty feature today. I have some powered JBL speakers for my laptop that I usually plug in to the headphone jack. I saw that the iPHone dock has the "line out" connection and I wanted to try it out.
So I unplugged the JBL mini plug from the laptop and plugged it into the dock, put the ipHone in the dock, selected a song from the iPod, turned on my speakers and voila! My iPhone now plays through my computer speakers, but without the need to connect with the computer. Thank you Apple.

I tried this, too, and found it only works with the iPod part of the iPhone. I thought it would be a good way to use the speaker phone, or at least listen to voice mail. But, it doesn't work. Has anyone tried this successfully?

Line out audio through dock connection

Does the nano have line out audio through the dock connector? The threads I've read here have conflicting information. The tech specs at http://www.apple.com/ipodnano/specs.html do not list this for the nano so I'm assuming NOT...and that my Sik Imp (http://www.sik.com/imp.php) won't work with the nano.
Anyone?

I suspect a documentation artifact here...
Apple originally supplied the dock std with iPod, but then subsequently removed it to make it an add-on accessory. Someone likely forgot to remove the mention in std iPod features, and also correctly did not include it in nano. The nano dock has an audio line out, just as all other docks before it since 3g.

No line out audio via dock connector

I have a Sendstation pocketdock:
http://www.sendstation.com/us/products/pocketdock/lineout-usb.html
I use the line out with other iPods including 4G ipod and 2G Nano with no problems.
But when I use the same Pocketdock with the iPhone, audio does not go through the line out, audio keeps coming out of the iPhone.
Is there a way to force audio out the dock/line out?

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,

Line Out in Software 2.0 Not Working

Shortly after upgrading to the 2.0 software on my 1st gen iPhone, I docked it in my Universal Dock, with some speakers plugged into the line out (like many times before). I didn't get the airport mode prompt, and it didn't chirp, like it always had. When I played audio, it only played through the speakerphone speakers, not through the dock. I restored the software and re-synced everything and it started working, but I've since noticed it not working on a speaker-dock, a Belkin iPod car charger with line out that I've used since I got the iPhone, and also in an iPhone dock (which I tried plugging my headphones into). It charges fine through all of the above, but the line out does not work. What could be wrong? Is anyone else experiencing the same thing? Thanks.

I'm having the exact same problem, or at least one very similar to the above one.
I have a first generation iPhone that is now on firmware 2.0.1
I did not try using the line-out on the dock before now.
When I put the iPhone into the dock (have tried both with power in from wall and from computer USB and without power as well) and connect computer speakers or headphones to the dock's line out with my iPhone in the dock I get no audio from the speakers/headphones... audio only plays through the phone's speakers.
How do I get it to switch to playing through the dock's lineout?

Audio line out mysteriously doesn't work due to software

My topic doesn't seem to fit in with any of the forum topics, so I chose this one as the closest fit.
Now, my line out audio stopped working. Now before you think I'm crazy and I submitted a question for what is obviously bad hardware, listen to this.
This happened before about a year and a half ago. I thought it was a faulty line out jack, and since computer was still under warranty, I took it in. They told me there was nothing wrong. I took the computer home and it worked just fine. hmmmmm
Now it happened again. I checked my speakers first by connecting to another computer. They worked fine. I rebooted the computer in Windows and the line out plays just fine into the external speakers! I reboot back into OSX and it stops working! Any ideas what is going on?
Of course I have the line out selected in the sound preferences. I can select internal speaker and I get audio from the computers speaker. Go back to line out and it's a blank. And yes, the volume is turned up.

Here's my advice...
Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then reinstall the combo update for Intel-based Macs...
http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
Repair Permissions afterwards, reboot.

"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.

No sound out of back line out MacPro Bootcamp 3.1 Windows 7 64bit

No sound out of back line out speakers.
MacPro Early 2008
Bootcamp 3.1
Windows 7 64bit
Realtek HD audio driver.
I have speakers plugged into the back line out.
They work in Mac 10.6.4 (as always) and in Parallels 5 Windows 7 using Bootcamp partition.
All other jacks work. In Realtek driver it shows nothing connected to that jack.
Anybody else have this issue?
Anybody else have solved this?

Anyone at all?
Even if you don't have the issue yet have a similar setup. Maybe I can figure out if there's a driver update I may need.
BTW I KNOW others have this as I've seen this mentioned on other forums. What I do NOT know is whether it's "everyone" or there's something about systems that don't have this issue, I need to follow.

Sound problems with back line out port

Hey everyone, I just sent an email to MSI Tech Support, but figure I would post a message here as well. I just put together a new system, but I'm having a problem with the back line out port.
My problem: When I plug in the front panel audio connectors (Left Audio Out, Left Audio Return, Right Audio Out, Right Audio Return) in the motherboard on pins 5-6 and 9-10 of JAUD1, the back line out does not work properly. I get sound on only the right speaker of the headphones.
More info:
- Audio Driver: 5.10.0.5620 (from MSI CD)
- If I instead plug the headphones on the front audio line out, then sound is fine
- Here's the strange part, if I unplug the front audio connectors from the motherboard (and short pins 5-6, 9-10 with the jumpers, obviously), then the sound on the back line out works properly!
- My Windows sound settings are fine
Has anyone heard of this problem? Any ideas/suggestions of what I could try?
Could this be a defective board? Could it be bad wires on the case? Seems unlikely since both back line out and front line out work depending on what I have setup.
Help! :-)
Thanks,
icab

Steve,
I appreciate the reply, but I believe you are wrong. Yes, I have searched the forum and did find that thread. Yes, I have read the manual. The only thing that it says is: "If you don't want to connect to the front audio header, pins 5 & 6, 9 & 10 have to be jumpered in order to have signal output directed to the rear audio ports. Otherwise, The Line-out connector on the back panel will not function." That's not my case since I want both ports to work (not outputting the signal both at the same time, obviously).
This can't be ByDesign. Either my board is defective or MSI is not following the Intel Front Panel I/O Connectivity Guide correctly. The whole point of having 4 wires for the front panel audio ports, 2 of the wires being Aud_Ret_R and Aud_Ret_L, is so that the audio signal is sent to the front line out and _returned_ to the back line out if nothing is plugged in the front line out.
I have an IBM machine with an intel mobo at work and it works as mentioned in the design guide.
Any other ideas, anyone? I can still RMA my motherboard, but it's a design issue, i guess I'm stuck. I never got an automated reply from MSI Tech Support, so I guess my email never went through. I'll send another email and let the forum know of the results.
Thanks,
Igor

Radio interference on the line in and line out

OK, this is a complicated one. For the past four months, I had a rather ancient PC. I used this to play music, as it was connected to a Logitech 5.1 computer speaker system, which was attached to the three ‘out’ ports in the back of the PC. I also had an electric piano connected to the PC through the ‘in’ port in the back of the PC. I was able to play the piano and hear the sound through the speaker system.
For Christmas, I received a shiny iMac G5. I quickly set it up with headphones from the line out. Everything worked fine. Then I set it up to use the 5.1 speaker system through the line out. Instantly, I heard a local radio station loud and clear. Furthermore, when I plugged in the electric piano (using the LineIn program), I heard not only the radio station but also a buzz. (When I disconnected the electric piano and used the headphones or built-in iMac speakers instead of the speaker system, there was no problem.)
Now I can recall a couple of times in the past four months where I thought I heard some faint radio station sound coming from the speaker system (then hooked up to my PC). However, it was so faint that I wasn’t even sure it was coming from my own room. In contrast, with the Mac, it is LOUD AND CLEAR. I couldn’t get clearer reception from my clock radio. We do have some major radio towers about a mile away, but they obviously weren’t a real problem with my PC.
The radio/buzz sound coming through the speaker system is unaffected when I increase or decrease the volume using the keyboard controls. However, the radio/buzz sound can be turned up or down through the keyboard controls when I use the headphones instead of the speaker system. The sound is unaffected by adjusting the on-screen volume slider on iTunes.
Granted, when I plug in the 5.1 system, it has three headphone-jack 'ins', so I had to use a connecter putting together two of them into a single 'in' and letting the other one hang loose. The radio volume increases slightly when I touch the loose end. This shouldn't be the source of my problem, however, because I still hear the radio (and buzz) even when I unplug the 5.1 system.
I brought the computer to my housemate’s room and plugged his speaker system in. The radio sound went away. (I wasn’t going to go through the trouble of dragging my electric piano over). But this didn’t do me any good, other than for research purposes, because I’m not planning to park my computer in his room.
I tried using a shorter cord between the electric piano and the Mac. No difference. I tried ensuring that the cord was never vertical at any point. No difference.
I called Apple tech support, sitting on the line for about 45 minutes in all. They could not help me, and could only direct me to the Apple Discussions site.
I read up on the Apple Discussions site, which suggested plugging the Mac into a different outlet. When I tried this, things only got worse. The radio sound was much more staticky. Even worse, it started up as soon as I plugged the Mac in – the Mac did not even have to be turned on. So I went back and tried plugging the Mac directly into the outlet to which the Mac was originally plugged in via a power bar (this time sans power bar). Absolutely no difference. I tried plugging the Mac directly into other outlets in the living room and the kitchen (which also necessitated plugging the speaker system directly into an outlet, rather than through the usual power bar). Absolutely no change. I tried wrapping the cord from the Mac to the speaker system in aluminum foil, as had been suggested on Apple Discussions. There was no change.
I tried using the “Sound” menu in “System Preferences”. I adjusted the output volume. No change. I muted the output volume. No change. I adjusted the input volume. This only increased both the radio and the buzz sound. When I turned the input volume to zero, both sounds continued.
I called my mother, who happens to know a thing or two about sound. No luck. I called my brother-in-law, who works for one of the big three internet companies. No luck.
I'll try to hold off with the editorial comments for now, but suffice it to say that this is my first Mac experience, and any helpful advice would go a long way toward soothing my feelings about Apple right now.
Thanks.

Yes, if I plug the electric piano into the Mac and listen to it through headphones coming out of the Mac, I get the radio sound (as well as a buzzing sound).
However, when I plug the electric piano directly into the speaker stereo system, bypassing the Mac entirely, I get only a small amount of interference/buzz. This makes me wonder if the Mac is, at the very least, dramatically amplifying the interference. (Again, when I formerly used the PC, there was a tiny bit of interference on rare occasions, but it was so faint that 99% of the time I did not even know it existed.)
I've also retried every possible combination in the old PC, just to make sure I wasn't fooling myself before, and at the moment I cannot pick up any radio interference there whatsoever, no matter how hard I try.
