Windows 7 64bit running as a guest in a virtualbox will not have audio enabled. The problem is the lack of drivers for the audio options, and thanks to this thread the solution is to download the driver and install it yourself. Works for me.
I needed to install windows 7 SDK on my machine. The installation works by downloading various pieces and installing them. Somewhere along the line, the download stalled. Its been that way for hours. Cancelling the installation brings up the dialog above asking me to wait while the operation completes. But that's the problem, the operation is stuck and won’t complete. Plus the dialog remains on top of all windows and won’t go away. Bad design.
Guide: Enable native NTFS Read/Write in Snow Leopard - Mac Forums:
"I am sure many of you heard that Snow Leopard was supposed to have native read/write for NTFS partitions. Apple supported NTFS R/W in older SL builds but I guess decided to not to go with it for some reason, however support is still present.
For this, you need to modify your /etc/fstab file to mount NTFS partitions for read and write.
First, uninstall NTFS-3G/Paragon if installed.
Open Terminal.app (/Applications/Utilities/Terminal)
Type 'diskutil info /Volumes/volume_name' and copy the Volume UUID (bunch of numbers).
Backup /etc/fstab if you have it, shouldn't be there in a default install.
Type 'sudo nano /etc/fstab'.
Type in 'UUID=paste_the_uuid_here none ntfs rw' or 'LABEL=volume_name none ntfs rw' (if you don't have UUID for the disk).
Repeat for other NTFS partitions.
Save the file (ctrl-x then y) and restart your system.
After reboot, NTFS partitions should natively have read and write support. This works in both 32 and 64-bit kernels. Support is quite good and fast, it even recognizes file attributes such as hidden files."
Lordy, lordy, lordy. They have no shame. It appears that Microsoft has just patented sudo, a personalized version of it.
Here it is, patent number7617530. Thanks, USPTO, for giving Microsoft, which is already a monopoly, a monopoly on something that's been in use since 1980 and wasn't invented by Microsoft. Here's Wikipedia's description of sudo, which you can meaningfully compare to Microsoft's description of its "invention".
There may be no single organization which runs more Linux systems than Google. But the kernel development community knows little about how Google uses Linux and what sort of problems are encountered there. Google's Mike Waychison traveled to Tokyo to help shed some light on this situation; the result was an interesting view on what it takes to run Linux in this extremely demanding setting.
