No Sound from External Mic
Hi. I'm on Lion 10.7.2 with the Lion Recovery partition deleted (I do an extrea Lion install in a USB external which has the recovery partition). The line in jack for the mic at the back (the built-in mic on top of the Mac near iSight works) doesn't seem to be working (I'm using a normal computer desktop mic, very standard basic computer mic with stand with the normal jack. It's from Creative). I've click in System Preferences-Input- Line In (instead of Internal microphone built-in) and in Audio Midi Setup for the Built-in Input, Built-in Output, Built-in Microphone, its all using 44100 and 2Ch-32bit Float. Do you need to use special microphones if you don't want to use the built-in mic and you wanted instead to use an external mic? Is the iMac (late 2009 i7) mic/line in connector at the back defective (is there a software to test that, like a Apple Hardware Test?)?
Thank you in advance.
Gbu.
