Stop the built-in mic's input level from decreasing during videochat?

Sys prefs/sound

I have been searching for a solution to this as well and don't understand why it's not as simple as un-ticking that box. Very frustrating issue.

Does anyone have any Audio Add-ons like Soundflower ?

Any issues in iMovie or Photo Booth of a similar nature ? (Is it system wide or App related)

Hi Ralph, I think I finally figured it out. Not very obvious, but the reason why some people have this issue. It is as simple of un-checking the ambient noise reduction box, however if you do this while you are using iChat video it takes no effect, and this is the only time I've been trying find solutions - while taking with others. So uncheck, restart iChat, auto input volume doesn't move.

Strange as this worked for me. Did she actually quit iChat or just close the window while the process is still active?

Hi,

She should open her Hard Drive and go to Library/Preferences and delete com.apple.audio.DeviceSettings.plist
She will have to go to this Folder manually as Spotlight does not look in there.

This is a a System Wide Preference that all Mac Users on her Computer would use if she had other Accounts set up. It is not a personal one for her (which would have been in her Home Folder/Library/Preferences)

I've delete that file and no different,
Any other idea?

Hi,

I have seen a couple of threads on this now.

The iChat 4 "Fix" does not seem to work.

Deleting the other .plist to do with Audio in that Audio folder in Snow Leopard also doe not help.

I have only seen it posted about internal mic on iMacs and laptops.

However I do not suffer from it myself.

I have tried changing an Audio setting and comparing the Date Modified column items to see if anything gets changed.
The SystemPreferences.plist in my Home Folder list that I opened the Sound preferences but not the settings.
None of the Audio .plists are showing any change. (in Hard Drive/Library/Preferences)

At the moment I am mystified as to where any setting is stored.

HI

We may need to look elsewhere than iChat for this fix, because I'm getting the same thing in Skype. When making a call the internal mic level moves up and down seemingly randomly. Its incredibly annoying, because there's no logical reason for the input level changes, it doesn't do it based on whats necessary....

I've unticked the Ambient Noise Reduction and restarted Skype and it continues.

Any more info on how to stop this would be great.

Hi,

It is going to take a search of the System Wide Preferences (Hard Drive/Library/Preferences) and anything and everything to do with Audio to find which one it is now.

I am noticing (and have had this for several years), that this 'sliding' of the internal microphone level seems to be some kind of automatic gain. I observe (using Skype) that as I talk, the slider moves both to the left and to the right. As I talk softer, it moves to the right, and when I talk louder, it moves to the left. (once I quite Skype the slider does not seem to 'auto adjust'). I am not sure how iChat is effected, as I don't use it.

I agree, this is an annoyance, as I would like to set the level and forget it. (unchecking reduce ambient noise does not change behavior).

Anyone know how to stop this 'auto level' feature?

Hi,

At present we do know that in the Console Logs iChat reports an Echo Cancelling issue that happens repeatedly - reducing the Volume to Zero.

Also at present we have no fix.
