We could use some additional details. * what version of CentOS 6 * what is your desktop GUI -- gnome or ? * what apps are you attempting to use with audio? I have CentOS 6.9 installed with pulse-audio and my gnome 2 desktop, and everything works well with this environment. I pretty much always test with Firefox and youtube. Sites with embedded with video also work fine for me.
