Question about Apple Griffin iMic External Sound System

Open Question

Imic cuts out and have to restart computer

I have been having a problem recently with my iMic which I purchased approximately 3 years ago. It may actually be a problem with Final Vinyl but I have downloaded the most recent version of that and the problem continues.
I am using an iMac with the most recent version of Leopard.

The problem is that I will be recording an album (converting analog to digital) and sometimes when I am doing this the sound cuts out completely on the monitor.
In order to describe exactly what is going on here I need to tell you how I have things set up.
I am running my turntable through an amplifier and the line out from the amplifier is the input to the iMic. I then have the output from the computer set to run back through the iMic and thus come out through the speakers from the amplifier.
That is, the input settings and the output settings in Preferences are both set for iMic USB audio system.
Then while I am recording something I monitor it by setting the amplifier to Tape Monitor (if I set it to Phono I would hear what was being recorded, but it would not tell me what the computer was doing, that is if the computer stopped picking up the signal, I would not know).
With this set up for no apparent reason that I have been able to determine at times in the middle of recording, the sound will suddenly cut out and the recording aborts. However, it doesn't exactly abort. If I look at Final Vinyl, there is still a signal showing and recording is going on, but there is no sound coming out of the speakers. When I check input level in Preferences there is a signal that shows also but it is not the recording of the LP. What it is exactly I'm not sure, but I suspect it is some sort of feedback loop which I will explain why and also what is going on with that continued input.
If I save the file that has been recorded to this point and import it into iTunes I discover that at the point when the sound has cut out, but there is still input, a recording has continued that consists of the last note of the original signal repeating over and over in a loop for as long as I let the recording continue.
Also regarding that continued input, even after I stop recording and turn off the amplifier, the signal still shows in the input of the Preferences panel. In order to get it to stop I have to switch the input to line in or internal microphone and then back to iMic USB audio system.
There is one more wrinkle which involves iTunes.
Once this stuff has happened iTunes will not play as long as the Output is set to iMic USB audio system, but it will play if the Output is set to line out/headphones. In fact if I set it to line out and start playing & then toggle back to iMic, iTunes stops playing but starts right up as soon as I switch back to line out.

The only fix I have found for this (which takes care of all the above problems until they occur again randomly it appears) is to restart the computer. Once I do that everything works fine for a time.

My question(s) then are if there is any known issue with the iMic that would be causing this? Would you know if it is the iMic or could it be the computer? As I said, the iMic itself is about three years old but the computer is only about a year and a half old (it is a 2.8 GHz Intel Core 2 Duo w/ 2 GB 667 MHz iMac).
What would you suggest as a solution?

An additional related problem is that the feed between the iMic and the computer will sometimes cut out when listening to music from the computer, even if it is not through iTunes, for example, this will happen when listening to a youtube feed.

I contacted Griffin and they suggested I reinstall a newer version of the software, delete any old playlists and versions, and repair disc permissions. I did all this and the problem persists.

SOURCE: iMick on Mac Mini

Yes, it does work for the mini (I have the same). Drivers seem to be built into the system, so you don't need to download anything with OS X 3.9 or later. Make sure your switch on iMic is switched AWAY from the mike input plug, and you may try plugging your iMic directly into your MacMini (or through a powered 2.0 hub).

Good luck.

SOURCE: iMic doesn't work with Logic Pro 9

I had a similar problem, but I managed to solve it; however, I'm using different recording software. The iMic simply does not have built-in input monitoring. Chances are, you are getting an input-signal but it is not being monitored. Try to find some kind of input-monitoring in your recording software. I found a toolbar, in my recording software, called "playback state" that has an option for input-monitoring. Search the help file index, within your software, to find something similar. Here's a quote from iMic's quickstart guide that might be of further assistance:

"In order to hear your turntable or microphone, you will need to enable an important preference in your recording software, usually called “Playthrough.” It may also be called Monitor, Passthrough, Cue, Preview, etc. Enabling such a feature tells the software how to route your audio, and is necessary for monitoring even when not recording."

Moreover, once you've solved this, I recommend using the iMic for both input and output, as latency with onboard-sound-output will likely be intolerable for input monitoring.

You could try double clicking on the amp image in the Guitar Track panel on the right of the screen, and when it spins around, you should see controls for Input Source, Monitor, Recording Level etc.
Select Monitor: On
I found that to be the source of my frustration, when I couldn't get any sound.
Hope this helps

Where can I plug in a microphone on my PC G4, need it to help in learning a new language?


It depends on which G4 you have. If it's a Quicksilver , there is no Mic in, and you'll need a USB audio adaptor to connect a microphone.
Other G4s, it's on the back, right next to sound out.

How can I make an MP3 recording of my voice on my PowerMac Mod. M6498 desktop?


You need a mic input. I did a slick voice-over on my G5 by using the mic in the iSight camera. It's a very good quality voice mic.
If you don't have that, purchase iMic from a local computer apple store. This will allow you to hook up a mini stereo plugged mic to your computer with a USB connection and you can record from within Imovie and also from the system preference control for sound input. Then copy the sound file onto a CD as an mp3..

Can you use the imic to voice over a recording. I would like to record my voice over a music background. This will be my first attemp; any suggestions.


You can use any microphone you wish is the normal answer, but the ideal answer is whether this is for a pro presentation or for a bit of fun you will erase later. If it's for a professional presentation, an external souncard (via firewire or usb) with a built in mic pre amp (this means it will have a a 3 pin xlr microphone socket on the front) is the best way forward and a better quality microphone. Myself I prefer a large diaphragm condesor microphone for good quality results. I would suggest the Samson CO1 as a sterting point, they do also do a usb version of this, which would mean you would NOT need the added expense of a new soundcard. Personally if you are planning on doing professional grade recordings, a new soundcard is highly adviseable.
If it's just for a bit of fun, use any mic you like as long as it plus into your mic socket .

Imic mon only-left channel is all that is seen


Audacity with Griffin iMic under Vista

There is limited and conflicting advice on the web about whether the iMic audio-usb adaptor can be used with Vista (for those who discover that new laptops commonly lack a stereo line-in port, and seek some way to use Audacity as described in the tutorial on capturing music files from vinyl, tapes etc).

In my case at least (Vista business 32 on a Thinkpad X200 with inbuilt Conexant Smartaudio 221 soundcard), it could be made to work as follows:

1. Plug the iMic device (iMic2 in my case) directly into a usb port on the computer. Allow the automatic loading of drivers by Vista.

2. Via control panel or right-click on the speaker icon in the system tray, access the Vista configuration for Sounds.

3. In the Recording tab, you should now see the added iMic usb device (probably designated as a microphone). The default set-up seems to be mono - so you need to make this change for this device: select Properties, Advanced, "2 channel...44100 Hz... CD quality".

I also disabled the built-in laptop microphone so there would be no chance of it interfering with recordings (or software conflicts?) - not sure if this is relevant but easy to test in the event that you strike a problem.

4. In the Playback tab, decide what you want as the default speakers.

The default seems to become the usb adaptor, but I changed back to the built-in speakers for monitoring - not sure if this is relevant but easy to test in the event that you strike a problem.

5. In Audacity (1.3.6 beta in my case): under Edit, Preferences, Recording, choose the iMic device and stereo. Project rate at bottom left of screen should match the quality chosen in Vista set-up for the device (44100 Hz).

6. While in Audacity, Edit, Preferences, Playback, choose the desired speakers (the built-in laptop set in my case) and click "Software playthrough" if you want to monitor what is being recorded (with a slight delay).

7. Immediately testing the set-up to record generated an Audacity "error while opening sound device". This only seemed avoidable by going back to mono settings in various places. BUT all is not lost...

8. Reboot! (With the iMic device connected in my case - not sure if this is necessary.) Ta-da ... all now works as desired for stereo recording. Use the same usb socket for the iMic in future, or you will have to repeat the set-up for each usb socket.

9. The Audacity volume sliders do not work under Vista, but you have several options to adjust recording volume:

(i) Use the slider under the Vista configuration for Sounds, Recording, iMic, Properties, Levels. For me this introduced a lot of hum at high settings, so I recommend keeping it below 5/100.

(ii) Use the iMic slider switch in the Mic position rather than the Line position, and fine tune as in (i) above. For me this gave the lowest background noise/hum.

(iii) Use the headphone out from your hi-fi amplifier and control volume there. This gave more background noise for me.

10. Keep the iMic device away from power supplies (it can pick up hum) and any source of vibration (if you tap it you will see a spike in the signal) while recording.

If you get hum, check whether it is from your laptop power supply (unplug and record using the laptop battery to see if the hum disappears). In my case there was unbearable hum from an iGo Juice supply, but much less from the Lenovo power brick.

After all that it is just about as good as my old Thinkpad X31 which has an inbuilt line-in socket and Soundmax audio card under XP.

With any luck the same approach will help with other ‘new, improved’ (but lacking line-in) Vista computers.

Check to see if the microphone works on the macintosh side of the computer, chances are it won't, microphone usage on Macintosh computers has been hit and miss, sometimes the microphone needs a pre-amp or USB interface like a Griffin iMic adapter.
