Forum Question: Audio/line-in/Sound System Preferences

Hey Gary I am trying to get audio through the “line-in” on my Mac. I changed setting of audio in to line-in in sound system preferences. When I choose audio input: line-in, and audio output: internal speakers, I get no sound. (Trying to get sound from a video camera, I know it works, because tried on my TV). Seems strange that I had to go get a free little app called LineIn by Rouge Amoeba to make it work and only by choosing the “Pass Through” button on the app. Can you explain a little about audio on the Mac and Sound System Preferences?

    The answer depends on some things:
    1. Which Mac do you have and what sound ports does it have? For instance, a new MacBook would have a single port for both sound in and out. Do you have a single port, or one for in and one for out?
    2. What are you using for a mic? If earbuds (both mic and speakers) then they are built for a single port (in and out). But if some other mic, then it may not be wired for the port on your Mac but a traditional mic jack.
    Using USB for mics is a much better option. But if you want to use a mic that is not USB, you may want to consider a small converter like the iMic: http://macmost.com/j-imic

      It is not a mic but instead the mono-audio out of an older sony camcorder. I am converting his videos from analog to digital. I am using a product called EasyCap with the Mac app EasyCap Viewer. The product description says if the audio does not come out to instead use the line-in of the mac by using a 1/8 jack adapter to a RCA which i did but no audio unless I use LineIn app with pass thru activated but with that I am not able to record the audio for his videos. Any suggestion on audio to digital converters for the mac?

        So, which Mac do you have?
        It sounds like the documentation is referring to the line-in jack on OLD Macs (instead of the combo jack on new ones) and that product isn’t compatible. Just get an iMic and you will be essentially adding a “line in” to your Mac. Or, try another converter product. Maybe Pinnacle Video Capture for Mac?

    Hmmm interesting! Combo jack? I have a new iMac 27″ i7. I saw the Pinnacle but he was the one buying the converter and I guess he did not want to spend a whole lot. I guess I’ll have to suggest. But I was just thrown off as to why I could not get adio out on my mac unless I used a third part “free” app that did basically allowed through put and could not understand why I could not accomplish this in sound preferences. Guess I’ll have to study up a little more on audio:)

      There is a “line in” on the new 27-inch iMac. But my guess is that whatever product you are using is just not compatible with either the camcorder’s output or your Mac’s input. If it was “cheap” it might just be a case of “you get what you pay for.”

    Lol. Yes I agree! Maybe we will see a podcast in future about audio on the Mac?:). Enjoy the keynote.
