Plug In Phones, Speaker Does Not Mute.
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!
Fred

Might have a look at amixer and see if you have an option you can alter similar to:
Simple mixer control ‘Auto-Mute Mode’,0
Capabilities: enum
Items: ‘Disabled’ ‘Speaker Only’ ‘Line Out+Speaker’
Item0: ‘Line Out+Speaker’
And see if you can set it ala:
/usr/bin/amixer -c0 set “Auto-Mute Mode” “Line Out+Speaker”

thanks for the reply. so far, that isn’t working, and I’m still perusing the man page. here’s what I get:
$ /usr/bin/amixer -c0 set “Auto-Mute Mode” “Line Out+Speaker”
amixer: Unable to find simple control ‘Auto-Mute Mode’,0
I also note that when I do amixer -c0 controls, the resulting list does NOT contain either “Auto-Mute Mode” or “Line Out+Speaker”
as permissible controls:
amixer -c0 controls numidB,iface
