Power Mac :: Why Can't Hear Music Keyboard When It Is Connected Through The Analog Audio Line-in Port
May 9, 2012
Why can't I hear my music keyboard when it is connected thru the Analog Audio line-in port? Looking at the System Pref. - Sound menu - in-put - Line in Built-in Audio, I can see activity on the input levels when I press the Kawai piano keyboard but no sound is heard. All other sound systems- I-tunes etc are operating properly.

My friend is looking into buying the new 27" iMac Core i7 to replace his PC desktop. The only thing holding him back is that he has an analog surround sound system he uses for his speakers. I am having a hard time myself finding a converter that can make his speakers work in the iMac's optical digital output port. Any products out there that will do that?

My 2.4 Aluminum MacBook has a very serious problem, but only with the line-in port. The headphones work fine through the line out. When I plug the microphone, the built-in mic still works,]. I tried everything, it just doesn't work at all, i plugged in the microphone and changed the system preferences manually and did everything with all the applications, but still, nothing is working. I have had this MacBook for 2 weeks now. I wish I waited couple of days for the pro.

I very confused about my line in port. I'm trying to hook my macbook up to my 4 channel PA using a 1/8" input jack, I am using garageband, but I get no response. the driver is switched to built in line in port but still nothing. I find that when I unplug it a little bit, the computer picks up the sound but there is a strange fuzz sound that accompanies it. So basically, the input does not work when I plug it in all the way. I know it worked before, perhaps I blew the input?

Would a standard 3.5mm audio input cable work? Would it fit in the port on my MacBook Pro? These are the cables I am looking at: [URL]. Port Image. I am looking at recording music from my Record Player to my computer with this Tutorial: [URL].

I have Final Cut Express 4 running on an iMac with Leopard 10.3.5. The problem I have is I cannot hear a music track & the sound track on the film clip at the same time when I run the clip. I only hear the clip sound track until it finishes then the music track plays. If I drag the scrubber bar along the time line I can hear both the music & the Clip sound track together. This only happens when I logon to the Mac as an Administrator. (I have never managed to hear both sound tracks together whilst logged on as Administrator.)
In desperation I created a user account on my iMac. If I logon as a user Final Cut Express 4 works ok ? I hear both sound tracks together when I play the clip. Any ideas how I can make the Administrator account work as the User account does? As the iMac is only used by myself I don?t need any user accounts.

I've read all the manuals, and the only thing that I can muster is that the audio line out port on the back of my Mac Pro "can be connected to powered speakers". So I connect it to powered speakers, and nothing happens. Is there some setting somewhere that I am missing?
I've connected it to the front headphone jack and got sound from the speakers. But I'd prefer to keep the cables at the back out of sight, hence wanting to use the line out port. The same speakers work fine with line level inputs from a Minidisc player, so I'm just wondering if the sound card has a dead port on the back.

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'm trying to plug in and use an external microphone to record a screen capture. Sound gets through the headphones great but, looking at Input Sound in the Sys Pref, the Line In device does not pick up any sound when I speak into the mic. If I switch it back to the Built-In Internal Microphone device it picks up my voice fine. In the Audio MIDI Setup, the Built-in Input device is selected as the device to be used for sound input.There is a switch on my headset to mute or unmute the mic and I've tried it in both positions. There is a volume dial on my headset (presumably for the headphones) and I've fiddled with that too. I've moved the Input volume for the Line In Audio Line-in port device all the way up and still it hasn't picked up a thing. I have a Mac os x Lion on a Macbook Pro and using a 3.5 mm mini-jack headset with two cables, one for the headphones and one for the microphone.

when you're recording, will the sound quality of the dual function line in audio port on the 13" be as good as the dedicated one on the 15"?
edit: the reason I'm wondering is because I want to convert old collections of vinyl records into digital copies at the highest quality possible and need to know if the 'line in' on the 13" will work good for that.

I have a G5 DP 2.0 and have been using it's built in ethernet port connected straight to my BT home hub (adsl/router) for years. Any way I add into the mix a netgear 1000Base layer 2 switch and the G5's ethernet doesn't work, reconnect straight to the router and all is fine. Now tested with new cables and tested on every port on the switch. By the way the port light on the switch don't light up when G5 attached. Now have tried the switch with a g4 and all is fine on every port and supprisingly I've stuck a PCI card in the G5 and that works as well. Just can't work out why the built in won't work through the switch but will direct.

I am trying to hook up the digital audio output on my cable box to the digital in on my dual 2.0 G5 running 10.4.9, 1 gig RAM. I have HDMI and component video out to monitor, but I use JBL creature speakers and sub for audio.
I have the propper cables and routing, sounds prefs set to digital in, and line out, to go to JBL creatures and first I get no sound at all. If I start AudioHijack and use same input and output settings all I can get is a hissing/clicking sort of sound. Same with using Soundsource and LineIn.
Audio MIDI Setup only shows or giveds me Built-in Audio for selections under system settings and properties for. Ausio Input and output show Master stream grayed out and I selected digital in and Line out for my sources and no change. Both ar set to 441000.0 Hz 2ch-24bit as well.

The analog audio input on my Mac Pro has stopped working.Audio output still OK; USB audio input works fine but nothing from analog audio input.I know it's getting a signal as I can send the mixer output to a Zoom H4n and it records fine, but I need it to go directly into the computer for tutorial voiceovers. I've tried recording in Quicktime Player, Soundtrack Pro, Camtasia and Screenflow.I get no volume indication in the System Preferences>Sound panel.I opened Apple Midi Setup>analog input and I can adjust volume on the two channels but "Master" is stuck at zero.

I'm one of the $200 suckers who bought an iPhone. For my $100 "rebate" I bought the new USB AppleKeyboard. I'm typing on it now. But when I first plugged it into the USB port, I got an error message like this: "The USB port is drawing too much power and it will be disabled." This is the same port the computer's original keyboard was plugged into and it worked fine. Now it's dead. The port is one of two USB ports on the back of my (original) Cinema Display. It's still dead. The AppleKeyboard is plugged into the second USB port now, and it works fine. But I thought I'd alert someone at Apple that this happened. Further, I'd like my USB port back but cannot find anywhere in the help files how to re-enable it. Unless it's fried, of course. But then again, how could the keyboard fry the port?

When I plug my MacBook into an external audio source via the headphone-jack using the red and white cables (do not know the technical name), I only receive sound out of one speaker. At first I thought one of my stereo speakers had blown out, but I plugged my computer into another stereo using another cord and it still only plays one speaker. Also, when I plug in any set of headphones I only still receive sound through one speaker (the left one). My computers speakers still work, and when nothing is plugged in it still says under the output type that it's Built-in Output. I also noticed that sometimes (but not every time) when I unplug something from the headphone jack that a red light flashes around two times, but it does not stay lit when there is nothing plugged in.
**Another note: The sound is not in mono in one speaker, it is just like one speaker is turned off.

Seems like it should be a straight forward deal, but it's not obvious how to make this happen. I can tell the audio is coming in, as the input levels are reflected under System Pref's. But I can't hear the audio on the line-out speakers and there doesn't seem to be an option to explicitly route the audio.

I purchased a Mac Pro last Thursday after running a G4 350 MHZ machine for far too many years. But it had been such a good machine I focused on it and took my eyes off of technological progress. I thought the PCI buses in the Mac pro were just faster versions of the kind of PCI in the G4. The G4 was outfitted with a Revolution 7.1 sound card from M Audio and that fed into a Creative 6.1 speaker system (with internal amp). The sound was amazing. It was my hope that I'd be able to transfer this card to the Mac Pro and discover even higher quality sound. But before I even tried plugging it in I did some checking and found that PCI Express is an entirely different technology than PCI.
M-Audio has stopped making the Revolution even though they still have drivers for OS X 10.5 (for folks who put this OS onto machines with the original PCI slots, I suppose). So now that this dream has shattered I am wondering what are my options for being able to hear great sound from my new computer. The internal speaker is OK for the beeps and buzzes produced by an OS that wants to get your attention but it sounds horrible when you're trying to watch a surround sound DVD. I'd like to hear from any Mac Pro owners who have found a way to make their computers deliver high quality sound. I know the Mac Pro has optical in and out but have no idea how I could make use of this other than to plug into a rather high priced surround amp.

I have a youtube video that is a tribute/interview of my grandmother, who unfortunately just passed away. YouTube has stripped the audio because on some parts of the video there is background music. I would really like to be able to watch/download this video with the audio - does anyone know a way to get around this?
fwiw: I don't have the original file, and downloading the video via pwnYouTube results in a silent mp4 file.

Ive had s few problems with my final cut. Im working off my laptop with a monitor. My immediate issue is that I have been editing fine this morning and then all of a sudden I could hear the audio for my clips but I can't see the footage in the viewer or the canvas. I can double clip on each clip individually and see what the footage is however. I've shut my computer down a few times and its not fixing itself. Also a lot lately when I sit down to do some editing the footage flickers on one clip and wont proceed to the next clips footage but I can still hear the sound.

I have audio that is being sent to my MBP through an audio in line that I would like to monitor for audio quality. The only way I know how to listen in real time to the audio is by way of Audio Recorder, but it seems a little unnecessary to have a recording application open simply to listen to my media that is being sent in. Is there a feature already part of OS X that allows me to turn this on? I looked in system prefs, but couldn't find anything to enable this. I will resort to audio recorder if I have to, but would be very happy if this was already a feature.
