Nice! I found this paragraph particularly useful:

30. Increased audio reliability
In some cases people reported not having any audio device after installing Beta. The problem is that some audio hardware does not work out of the box with our inbox audio class driver. Amazingly there are over 26,000 custom audio drivers and while many are on Windows Update, many are still not. The Release Candidate tightens the Windows Logo test to better ensure clean install delivers baseline functionality for speakers and microphones. Furthermore, we will continue to populate Windows Update with frequently needed drivers.
