How to get Google search back into Safari's Toolbar

Hey Scotty,

You helped me set up my email account during an in home consult previously.  I have a question that I hope you can answer.  My internal speakers aren't working.  I am not connected to an external source and am not using headphones (I am at a hotel away from home and don't have either to check via that method).  I looked at apple.com and tried to troubleshoot that way and checked my sound preferences but nothing seems to help.  when I do click on something to start playing (in itunes, for example) there is a cracking noise but i can't hear music.  Any thoughts? Should I just go to the genius bar to check it?

Thanks,

I suppose you’ve gone to the system prefs and looked at sound output and checked to make sure that output is set to internal speakers.
It would be great to know if the headphone jack had problems as well. There’s always a chance that it has become a hardware issue that the Apple Store would need to address if the unit was under warranty. But let’s say it’s a software problem. Possible offending sound files that could result in this problem are as follow:

~/Libary/preferences/system configuration/preferences.plist
~/Library/preferences/com.apple.audio.DeviceSettings.plist
~/Library/preferences/com.apple.audio.SystemSettings.plist

Throw away all three of those files then restart your computer. If it’s software, there’s a good chance the problem will disappear. However, these files will be recreated with new settings. You’ll need to fine tune. Only a minor detail. For instance, volume level. Check to make sure you are connected to wireless once again. You may have to reconnect manually because that first file could contain other settings that may be reset besides sound.



Hope this helps.
