Hello, this is my first ticket, as I have not had any other problems with rEFlt bootloader. I have noticed however that there is no audio playback on my MacBook pro when I switch to Win/8 from rEFlt. It works fine on OSX Mavericks though. I have attempted to troubleshoot audio playback several times while on Win/8 and it hasn't been resolved. For some reason, the computer identifies when the headphones are plugged in but no sound ever comes out of the plugged-in headphones. I have even tried going into the device manager and updating the drivers for the audio devices. If you have a solution let me know.

-Thanks, Cobra out

    rEFIt isn't being actively supported. You should try rEFInd instead.

    This is probably not a rEFIt problem. Try booting Windows by bypassing rEFIt, either using the Startup Manager (hold option key at startup) or using the Startup Disk preferences panel in System Preferences.app.

    What model is your MacBook Pro? Are you booting using EFI or BIOS?

    Have you installed the Boot Camp drivers? What version of Boot Camp drivers are you using?

    You don't really need rEFIt or rEFInd unless you have more than one legacy OS (boots using BIOS) on the same hard drive.

    Joe, I have a 2009 Macbookpro with duo core processors. 4 gig ram. I can't tell you exactly what the specs are as I'd have to boot from osx and get info on the "about" tab. I am booting from BIOS I believe. No, I haven't installed bootcamp on osx. Also, my I am booting on the same hardrive. I just have mac and win/8. No Linux.

    -Thanks

    Why can't you boot OS X?

    The document at http://support.apple.com/kb/HT5634 says that Boot Camp 4.0.4033 is the latest version supported for your MacBook Pro (http://support.apple.com/kb/DL1630) but that is for Windows 7. Try installing that in Windows 8. If it doesn't work, try installing the audio driver manually.

    Did you install Windows 8 32 bit or 64 bit? I think Boot Camp 5 is 64 bit only.

    You could try a program like Driver Genius to find drivers for your computer. http://www3.softcity.com/driver-genius/
