The speakers are easy to fix, just go to the RealTek website and download the latest
drivers for the RealTek HD sound system built into the MB.
If you do not use the web cam then don't worry about it. I do not use mine, nor do I use it on the Mac side, so I never lookrd for a fix. Though you should be able to find a fix by using google/bing to locate the
drivers for that particular web cam.
As far as performance counters I can offer you no help there. It would appear that I didn't need them so it is not an issue on my system.
Hope this little bit helps. I think once you get your sound
drivers installed you shouldn't have any real problems. Good Luck.
