I have buy a pc with AC97 audio in front panel (rear panel is HDaudio). So in uefi settings I have set front panel to AC97. Normally, I have audio in monitor speakers (Line Out Built-in Audio), and when I connect a headphone in front panel, I have audio in headphone AND monitor speakers. I want only have audio in headphones but "auto-mute" option is not listed in alamixer. The only way to get mute the monitor and have audio only in headphone is select "Headphone - (Built-in) Audio" in sound settings from gnome and down to 0 the item "Front" in alsamixer (See screenshot). The problem is that if I change the output device to "Line Out Built-in Audio" and then I select "Headphone - (Built-in) Audio" after, the settings for alsamixer is lost and the item "Front" is set at 100 again :/.
My specs:
