Centos 7 - Headphones silent - workaround

Post by chlowden007 » 2021/06/22 08:17:58

Maybe my discovery might help someone.
For sometime, when I connected headphones to my Dell laptop, the OS would offer a connection for Headphones, headphones & mic or mic only. In the Sound System prefs, I could see the headphones icon but all was silent.
After many tests, reading lots about reinstalling ALSA etc etc, nothing worked.
By accident, I noticed that the Sound System Pref INPUT tab was defaulting to Microphone - Built-in Audio
When I clicked on the Headset Microphone - Built-in Audio, the headphones started working.
