    So I've been following the MBP forum for their Audio Volume issues because we seem to have the same problem. Check out their issues here:

    There is also an apple discussion here.

    I have a Late 2008 MB running both Leopard and Boot Camp with Windows XP pro SP3. Under boot camp it uses the RealTek driver for the sound card. It is putting out very low volume. Many people have posted similar problems with Vista and windows 7.

    Here's the test I did to confirm. I made a 1kHz test tone audio file and played it out of OS X. I connected the output of my headphone jack to a volt meter and measured a little over 1V or 1000mV. I switched to Windows and played the same file. This time I measured 280mV. This proves that the RealTek driver is not sufficient and does not measure up the full potential of the Macbook.

    I've called apple on the issue and they say that it is not their problem and they do not support it. Even though they advertise that Windows is fully functional under boot camp. The solution for the MBP was that someone modified the INF driver file. Unfortunately, Apple uses a different chip in the MB and this solution will not work. I tried it.

    So PLEASE post here if you are having similar problems and/or if you have a solution to the problem.

    I have the exact same problem. It's quite annoying. Who to contact for an update? This doesn't make any sense. :/

    Works on MBP 15 inch XP Pro 32-bit

    This works swimmingly for me. You can choose to turn off the red light or leave it on as well. It also lowers headphone volume so that it doesn't blow your ears out. Excellent!!

    I have a early 2009 MBP but the driver fix just increased the volume about 30 percent but not back to the volume level when running on the Mac side.

    Is there anything else I could try?

    Uhh, I've got the new 2010 13" MBP and I have the same very low volume problem under Vista SP2. As a matter of fact, the drivers on the Apple disc did not work at all and I had to search and search until I found a Cirrus driver that worked. Can anybody hook me up with an updated one for Vista? Pretty please? :D

    Man, I'm always so close to a solution. I'm running Windows 7 64bit with BootCamp 3.1. Any chance you may have these drivers for a 64bit user? Or anyone have a solution for the low volume for 64bit users? Thanks in advance!
