Hopefully you have had a chance to update to build 10041. We have made many improvements in this build and we're looking forward to receiving a fresh wave of feedback from you.
I wanted to take a minute to provide you with an update on the state of Audio in this build. Many, many of you have been very helpful in identifying and diagnosing issues with me and I want to offer my sincerest thanks for your help. Hopefully you'll see some issues fixed in 10041 and you'll be willing to help me with continued work on existing and new issues. :-)
