Hi all. I've got a problem with my iMic. If you play back a recording that you have made, you will hear a 'clicking' or 'popping' noise in the sound track. I have mailed Griffin, and apparently it is a known problem with all apple portables. When the hard drive is being written to by a sound recording application, electrical interferance is picked up by the iMic and is translated into a clicking/popping sound. The sound is only there is you listen carefully, BUT the whole point of me buying the iMic was to get as good a quality sound into my PowerBook G3 (firewire) as possible with as little money. Not worse.

Another thing I have noticed is if you use the 'play through' feature of it to monitor an external sound source, the sound will come out of the Mac's speakers very choppy and will cut out every couple of seconds. BUT, this cutting out is not evident in the recording if you play it back. Just whilst you are monitoring it with the play through feature. I tried it on my G4 (466) and it was fine. No chopping out and no clicking. 100% perfect.

have others noticed any problems with this device when using it on an iBook (primary target audience) or powerbook?

thanks
stu

I have an iMic as well, I found it is only good for realplayer for online radio playback. But it is worth the $$, esp for cube and ibook, which have no audio o/p. I have all kinds of problems w/ iMac, the poping noise that you mentioned, usb dropout... well, it is cheap. You may want to use Ram disk for recording to avoid the interferance, then save it to HD.

There is a firmware update on Griffen's website; don't know if that will fix the problem. But, VM and Filesharing should be turned off when recording.

Just as an aside, the (new) iBook does have an audio output. It's an audio input that is missing which is why I too just got an iMic and I'm a little worried about these reports of popping!

(I haven't got any recording software installed yet so I can't test it other than seeing the bar graph flicker in the Sound control panel and play audio out from iTunes. Planning to install ProTools free later today.)

Well I just installed ProTools Free - I have Virtual Memeory and filesharing off and sure enough glitching all over the place... so did I just waste £40 ??

Me again. At the suggestion of a colleague I turned AppleTalk off and it seems to work ok now - that is to say a Griffin iMic on a dual USB iBook using ProTools Free
