We are aware of an issue with Chrome 23 and Flash Player where your audio will be distorted. We have tried various ways to work around this so that users would not have to do anything, but we could not come up with a solution. The Chromium team is aware of this bug and is going to fix it (http://code.google.com/p/chromium/issue ... ?id=157613).

1) In the URL, type in "chrome://plugins"
2) Expand details in the top right corner (it should be a minus instead of a plus sign)
3) Search the page for "pepper"
4) Click "Disable"
It should look something like this:
