Hello! If you see this, you are most likely using an ad blocker. (Or maybe you have JavaScript disabled. Or maybe my web server is down.) I have no problem with ad blockers; in fact I use one myself. If a site tries to deny me access unless I disable it, I just find a way to circumvent that. But if a site politely asks me to do so, but still allows access to the site, I disable it for the site. I am asking you to please do the same for this site. I can't make you, but I would appreciate it. Thank you! :-)

Fix audio problems when running XP in Boot Camp

I have Windows XP installed on my MacBook Pro with Boot Camp, and until now I have been having two problems with the audio. One is that the volume is way too low, even at max. The other is that certain programs, such as the Source engine (games like HL2, Portal, TF2, etc.) don't work with the microphone. However I have recently come across a modified driver that fixes both of these problems. I didn't see anything about the mic, but it fixed it for me.

Here's the link:

To install it, extract the archive to your desktop (it's already in a folder) or anywhere convenient. Then, open Device Manager (Start > My Computer (right-click) > Properties > Hardware tab > Device Manager.) Expand "Sound, video, and game controllers" and double-click "Cirrus Logic HD Audio". When the Properties dialog appears, click the "Update Driver..." button. Choose these responses I have outlined for you here:
  1. No, not this time
  2. Install from a list or specific location (Advanced)
  3. Don't search. I will choose the driver to install.
  4. Have Disk...
Now navigate to the folder where you extracted the drivers, and double-click the .INF file. (It should be the only one visible in that folder.) Two options should appear: "Cirrus Logic HD Audio [MacBook, No S/PDIF Out]" and "Cirrus Logic HD Audio [MacBook]". (I'm not completely sure about the name of the first one.) To find out which one to choose, look at your headphones port. If it's glowing red (yes, it lights up) choose the latter. Otherwise, choose the former. It will probably warn you that it's not signed, but just tell it to install the driver anyway. The problems will be fixed, and you shouldn't even need to reboot!
