Hey you guys I want you guys to try something. Becuase I want to see if this is just my Mac or if it really is some sort of glitch. First log on to OS X (I have 10.5.7). Then mute your sound. On my unibody Macbook Pro I pressed f10. Now reboot and hold option to logon to Windows 7. You wont here the Windows chime becuase the sound is muted, makes sence. Finally hit f10 or unmute your sound. Do you guys here anything? For me I couldnt find a way to get sound back from Windows. I would have reboot to OS X unmute and then reboot back to Windows 7. Kinda annoying. What do you guys think?
