I even reseted PRAM on my mac pro by rebooting my machine and pressing the Command+Option+P+R until the white screen appears (see the apple way of doing reset PRAM on your model of mac and for more details). That was the 1st indication that the problem is software problem and not hardware problem (the mic is still working) and somehow it get muted.!!!!? I opened on windows the program of the logitech to record a video with sound and the mic was not enabled. I un-muted it and at the properties panel I saw that the green bars was moving (indicating that the device was receiving sounds through the logitech's mic. I Played somehow with the properties (on windows) for the camera microphone and found that it was muted. The problem on linux mounting an unproperly unmounted USB HDD from windows solved and I thought that some kind of "same logic" could solve the problem for the mic of the logitech camera I was almost wrong.!!!!) Then go on linux and mount as usually the HDD. After a lot of search for the HDD issue solution on many linux forums, I found that I had to mount and unmount the usb hdd on windows.
(I had a hope that maybe something was "Stuck" for the camera and that if windows with the native windows drivers of the camera could "see" the camera in it's nature environment, it should be un-stucked or something.!!! Lool.!!!!) (If you find my "windows seek for help" behavior strange read bellow for an old linux problem I had once, when a USB HDD Stacked and couldn't mount to my linux system because it was not properly unmounted on windows (unmount on windows = "Safely Eject Hardware"). I tried to check the camera on Windows / Virtual Machine (Fussion 3) and discovered that the microphone didn't work at windows neither. Today I tried to do a skype video call again with one of my friends and discovered that the microphone didn't work at all on my OSX Snow Leopard 10.6.5.įirst I checked the preferences on my mac osx.
I am on a mac pro 2009 and use the "Logitech Pro 9000" (PC Version) usb Camera without a problem for about a year.
