I've got an Acer laptop model Aspire 4810TZ-4696 and I recently got from Acer the new Windows 7 Upgrade (used to have Vista). After upgrading everything works correctly except for my microphone. In Audio devices under "Recording" the microphone(Realtek high definition audio) appears to be all ok, it's default device with a green check mark, it's not on mute and volume's at max. It says the device is working properly and I've also checked for updates for the driver which says no updates available. So apparently it should work, yet when I try calling with skype it says "problem with recording device" and when i test the microphone on skype it says the microphone seems to be working fine yet when i try test recording on skype nothing happens.
When I try "sound recorder" on the pc it says "an audio recording device cannot be found" and when i try "set up a microphone" it says "make sure your audio hardware is working properly and check audio config ect...".
I've tried running "find and fix audio recording problems" but it doesn't detect any problems.
I've checked various topics on the issue but no one seems to have the same exact problem I do.
I've also used Windows 7 Upgrade Advisor which said there are no compatibility issues.
Does anyone know what the problem is and what can be done to fix it?
Any kind of help will be very much appreciated since the issue is urgent.
