The sound is always "muted" when Windows 7 boots up (64-bit) MacbookPro i7

I just got my shiny new MacBook Pro 17" (i7) via Federal Express from the Apple Store, to Shanghai China, to Alaska, to Los Angeles. I loaded Windows 7 Ultimate with Bootcamp 3.1 drivers and updated Windows with "Windows Update". Every time the computer starts the sound is muted and I have to manually un-mute it. Is there a solution? Thanks.

Mac Pro (March 2009), Mac OS X (10.6.3), Mac Pro (March 2009); MacBook Air (2.13); Macbook Pro (i7)

If you look around these forums this is a issue being reported by a lot of people with 2010 MacBook Pro's. Hopefully a fix will be forthcoming.

Hey I figured out the solution.

1. Plug in a set of headphones
2. Go to sound icon in taskbar and right click playback devices
3. Right click the headphones and set it to Default Device
4. Right click the speakers (Cirrus) and set it to Default Communications Device
5. Profit

Took me a day to figure this out, but it works for me. Goodluck!

Hello, I have experienced this as well. I don't know if you have resolved this already but here's what I noticed on mine: if I remove my password to login and start up Windows, it will start up muted. Then, when I used to a password to login, Windows starts up with sound.

Okay -- it took a year -- but I just fixed it. Here is what I did. I upgraded to BootCamp 3.2, but that didn't do anything to fix the issue. Then I went into the sound properties, under the section entitled play back devices, speakers, enhancements -- check the box to "disable all enhancements". This was the clue because without checking the box to disable all enhancements, the status was listed as being "disabled" and settings were unavailable to select -- the device manager showed no problems with anything, and uninstalling the sound driver and rebooting did not fix the issue.
