Sound problems with Chrome 24 on Mac OS X 10.8.2
Shortest article ever written on my blog…
From time to time I notice that switching from my audio local source to my Airplay station (and the other way around) somehow muted the sound on Chrome. After some googling I noticed that the problem came from a flash player plugin. You just need to disable it.
For this go to chrome://plugins, Show details an then disable the PPAPI plugin located in:
/Applications/Google Chrome.app/Contents/Versions/24.0.1312.52/Google Chrome Framework.framework/Internet Plug-Ins/PepperFlash/PepperFlashPlayer.plugin
Hope it helps! `
