Turns out, the real problem is a conflict between the built-in Flash plugin in Chrome, and the Adobe one that I must have downloaded elsewhere. After some digging, I figured out that it is just Flash related. There’s nothing wrong with Chrome, or the sound, but it just wasn’t working. For Google Chrome, see Enable Flash Player for Chrome. For Safari on Mac OS, see Enable Flash Player for Safari. 2) On the content settings screen, locate Flash player settings. Enable Adobe Flash Player on Chrome 1) Open your Google Chrome browser, type chrome://settings/content in the address bar and press Enter.
