Hi all! Using C6 on an Asus M5A99X EVO R2.0 motherboard with AMD six core FX6300. That board uses Realtek ALC892 audio chipset. For the first time since I got that motherboard I tried plugging in headphones to the front panel speaker output. I was somewhat displeased to note that the speakers don't mute when that happens. I recall seeing info on that in Fedora, but not Centos, and haven't so far scared up how to troubleshoot it. I can MANUALLY change the setting in sound preferences, which offers only two choices: "Analog Output" and "Analog Headphones". Suggestions will be welcomed!
