Audio line in port

please describe the characteristics of mics that will (or will not) function with this port. (e.g self powered ?)

  • What is the "Audio line in" port for?

    I have a microphone headset but plugging the mic cord into the audio line in port does nothing. Similarly, when I tried plugging a cable from the "tape out" of my audio amplifier into that port for dubbing purposes, nothing happened. In both cases I can achieve what I want using an iMic and a USB port. So what's the audio line line port for? How can I use it?

    Check your Sound settings in system preferences and audio midi set-up, Brian. It may be that you have it set to accept sound in through USB at present. Another possibility is that the port has "stuck" on "optical input".
    Cheers

  • Audio line out port (Apple iPad Dock Connector) not working Iphone 4 os 4.2

    For my new iphone4, the audio line out port (Apple iPad Dock Connector)is not working. Both using a cable to mini jack (3,5 mm) or in dockingstation.
    I'm using OS 4.2.
    IS this a bug?
    Thanks
    Hans

    I just came back from the Apple store.  My iPhone4 DOES have a working line out when plugged into a Apple name brand dock connector.   I don't know why my SendStation refuses to work only with the iPhone4 yet works with iPods, etc..
    Solution? I'm buying an Apple iPod dock connector for home and will try to find something with line out for the car - Apple says they do not make one.

  • Audio line-in port - input level shows sound but nothing from speakers

    I have a Genus DAB radio attached to the Audio line-in port on my Macbook running Leopard 10.5.3. The input level meter shows sound but nothing is heard through the speakers.
    I have tested my headphones and connected the radio up to a PC and all is well, ca anyone suggest a fix for this? (I have seen the same issue elsewhere on this forum with no replies).
    Many thanks,
    Gary

    What audio application are you using to pass the audio through the input to the speakers/headphones?

  • Audio line-in port stopped working properly

    I started to have a perplexing problem that I narrowed down to the audio in-put port on my Mac Pro (MacPro3,1). It was working fine then the sound level increased and the quality became distorted (like a "fuzz base" but affecting all sounds).
    I was in the process of digitizing records, and believed the record played broke. So I got a new record player (audio-technica AT-LP120-USB). The same thing occurred with the audio in-put port, so I switched to the USB port and the audio was fine. I also checked with music already on my HD and it played fine. Consequently it has to be the in-put line port and/or a software issue.
    I checked BBs but could not find a similar issue.
    Any suggestion?  Thanks in advance.

    Since this is a Mac Pro question I'll request this be moved to the Mac Pro forum.  You posted in the PowerMac forum which is pre-Intel Macs.

  • Connect iPod to MacBook Pro audio line-in port?

    My 1st Gen iPod's Firewire port fried recently; it still delivers a charge to my iPod but won't allow it to mount. I can still listen to music with the headphone jack.
    What sort of cable can I use to attach my iPod to the audio line-in on my Macbook Pro?

    I also have this problem but with a slightly different twist..
    I was using my plantronics (old ms gamevoice headset) with 10.5.2 and it worked, then installed the m-Audio Firewire Audiophile beta drivers and neither the audio-in or the m-audio audiophile line-in cause any VU-meter response (nor input) whereas the standard inbuilt microphone does.
    After uninstalling the m-audio drivers the situation is still the same.
    Oddly - if I plug in the headphones into the line-in (rather than microphone) then speak into them I actually get input audio (and VU-meter response) through the MBP's audio-in.
    So the story about no power is used (hence the headphones create enough to register the sound) sounds about true... very annoying as I thought my old headset had died and went out and bought a new one.. that still doesn't explain the audiophile input issues..
    Now I fully expect both companies to point fingers at each other.. I don't care - just get it fixed please.

  • Faulty audio line-in port?

    Hi, I've just bought a 'Monster iStudioLink' lead to record a guitar onto my Mac using Garageband, but something isn't working!
    I've gone into System Preferences to check if there is a sound input and the iMacs internal mic is working fine but theres no audio line-in signal.
    Does anybody know if there is a way that I could check if the line-in is faulty or am I doing something wrong?
    Thanks

    First make sure you are plugged into the
    imput jack not the headphone jack
    (Ive done that many times)
    If you are going direct from your guitar
    you may need to go through a pre amp first.

  • MacBok pro Audio line in port  doesn't work for microphone input Why?

    I turn line-in port  on in System preferences/sound but no reaction. Using within third party applications like Hear or Amadeus the recording via head set microphone is without problem. What is wrong with the Mac os ?

    Actually, I've found the following problem with mine:
    If the jack is stereo jack, the computer is in "line in" mode, where you need higher signal level (approx. 500mV afaik) which no passive microphone will provide. If the jack is mono, it "looks" for an external microphone and it works.
    Both sockets (in and out) of the MBP are intelligent, in the sense that they detect what's connected based on the jack configuration.
    I have a headset with a stereo pink jack (the microphone) and it is not working. Another microphone that I have, with a mono jack works flawlessly.

  • Audio Line-In Port Not Working

    I plugged a Shure mic into the Audio-In Port and is doesn't work. I'm using FCP Voice-Over but I get no audio on Soundtrack either. Worked with all the settings and preferences for audio. Also tested a second mic which also doesn't work. I read some people had problems with Audio-In Port after upgrading to 10.4.10. I ran a check for audio updates, there are none that I haven't installed. Why can't I seem to make a simple mic work when it's been so simple previously?

    Your Mac does not have a microphone input, only a line-level input (in fact, no Mac has included a microphone input in quite a while). So you'll need 1) a self-powered microphone that outputs line level, 2) a USB microphone, or 3) an external audio device that supports microphone inputs, either a mixer that will give you line-level output or a USB audio input device. One possibility for a USB device that works for many people and that is relatively inexpensive (ca $40.00 US) is the Griffin iMic. It works with any standard personal computer microphone.

  • Where is the audio line in port on my Macbook Pro with Retina Display?

    i want to find a way to connect my guitar into my macbook, and i cant seem to find a line in port

    there is a headset jack, and of course the USB port.
    Most guitars need to be run thru a converter to USB

  • Audio Line-in Port not working after upgrading to Lion

    I have recently upgraded to OS X Lion...
    since then, I am trying to continue my Rosetta Stone program, and it hasn't been able to detect a mic.
    So i opened system prefs and looked and it won't register any of the 3 different mics I have plugged in.
    The input level never increases, showign that it doesn't even recognize something is plugged in.
    I didn't have this problem until I upgraded.
    Please Help!
    thanks,

  • Audio line-in analog port - no sound

    I have an MP3 player plugged into the audio line in port. I cannot hear the audio. I have selected the correct input config (audio line in). I have all my volumes and mutes in the correct positions. I can see the audio is modulating the VU meter yet no sound comes out. I can also play music just fine from iTunes or other files on the computer. What is the problem here? Does anyone have any suggestions?

    Good Point. I am using Sirius. I do realize you can use their streaming audio but there is less info and control. I have the home adapter kit and just thought when not in the car.....
    Shouldn't pumping the audio out from the radio go through the audio input on the iMac?
    Also, streaming isn't all that perfect. Rebuffering, interrupted connections, etc. uses bandwidth and processor resources or so I think. I don't wish to record just play back. I know I have used the audio input on my G3 iMac with a video camera but perhaps that was because I was recording therefore the sound monitor was turned on. I just don't remember. I really think I have a setting or box checked wrong somewhere.
    Thank you for your response. No matter how much info is posted on a support site it never compares to talking with other users.
    I'll keep digging. Have a nice weekend.

  • Line-in port not showing in sound preferences

    On my G5 in system preferences/sound/input, "audio line-in port" doesn't appear.  Only "internal microphone" is listed.  Anyone seen this before?  Thanks.

    In case anyone viewing my question has the same issue, here is the solution I discovered:
    Go to Applications/Utilities/Audio MIDI Setup
    Under Audio Input/Source choose "Line In"
    Good luck!

  • W520 audio line in / line out

    Whenever i connect a 3.5mm cable with the line in/out it gets interpreted as a line out (headphone) cable. The line in gets displayed as not connected. Is there any way of switching the interpretation? I don"t need line in + out simultaneously, but i"d really like to use the line in as well

    Does any one know how to setup or switch Audio line-in port in "W520 conexant 20672 in Windowns 7 64 bit"?
    Does W520 Microphone jack support 3.5 mm audio in from iPod or any other sound device.
    I have Mac book pro, they can do switch between Internal Microphone to Audio Line in.
    How come this expensive W520 laptop can't do this?
    Lenovo service group people doesn't know how to do it. Please help fix this problem that very appreciated.

  • Audio line -in : doesn't seem to be responding

    Hi
    My audio line-in port doesnt seem to be working any more.
    Does anyone have any advice to help me trouble shoot this issue.
    Ive already tried third party recording apps and a new set of mic-headphones but still nothing appears to be coming through.....it worked fine previously and was used often.
    It may be an emac hardware issue or a system issue where i updated to Tiger a few months ago.
    But perhaps it's something else !?
    thanks for your time.

    1. The type of headset im using is manufactured and ubiquitous for use with any pc or laptop
    see for example :

    or
    http://www.techfresh.net/wp-content/uploads/2007/11/plantronics-mono-headset-for -internet.jpg
    or
    http://thevoipgirl.com/wp-content/uploads/2006/08/headset.jpg
    which are close to the ones i use. I know they're the cheap end but they are very common - Don't they just get their voltage from the mac itself ??
    Also
    2. Mine worked fine until recently - which means i was able to speak into the mic and hear it in software and adjust the audio input level in the O.S. sound prefs and now can no longer do this because when i have line-in selected as my source it's not showing any reciept signal in the display level indicator.
    The simple fact that i was previously for several years able to operate one of these mic head-sets suggests that the issue must lie elsewhere and is has not been about the headset amp level as you suggested- My concern is that it is something to do with the OS Tiger which i recently updated to .....simply because it's the only major change i have in the recent past - i can't think what else it could be or what trouble shooting procedures to follow on this type of problem....
