Written by Tanu Kaskinen, from the PulseAudio Team:

With speakers plugged in to the green connector on the back of ASRock B75M-DGS R2.0 motherboard[1] (with Realtek ALC662 audio codec), the speaker audio can't be muted without muting also front panel headphone output. The mixer has playback volume and switch elements named "Line", which I would expect to control the speaker audio, but those mixer elements don't seem to be doing anything.

Hello,

Is there anything I can do to to at least help debug this issue? I have to do this workaround[1] each time there's a Pulseaudio update... FYI I'm on kernel 5.2.14 now.
