Hey everyone, this will actually be my first post here as I just joined MacRumors and find this may be the right place to post this. I cannot seem to get any sound or volume adjustments when I just did a install of Lion on my MacBook Pro (Mid-2009) model. I just recently bought a new SSD and just did a clean install of Snow Leopard and immediately installed Lion right after to see that the sound would not be able to be adjusted. The sound did work on Snow Leopard but not on Lion. Now the things I have tried doing was to plug in a headphone and then unplug it. That works and everything will be fine, but as soon as I restart or Shutdown the computer then its back to me not being able to adjust the volume until I plug and unplug a headphone. Theres a screenshot to show you guys what I mean that happens. Please, if anyone can help me solve this problem, that'd be real great.
