No sound through speakers, only headphones

[JTolliver]

Hello,

I have recently updated from Fedora 14 to 15 and there was no problems; sound worked great. I may have updated some packages or installed new ones, but I do not know the cause of my problems. I believe I installed some gstreamer modules for mp3 support.

Things I have done:

• Installed: pavucontrol
• Reinstalled: pulseaudio
• Checked alsamixer for muted components
• Looked for hours for a solution

I'm using Sony VAIO model: VGN-AR370 (mistake, I know)

I'd appreciate any help and will try to get back to any questions asap.
