** Description changed: On the Lenovo P52 machine, there are dual analogue codecs: the 1st one contains the speaker and front headphone, the 2nd one contains the rear lineout. As there are two codecs, there are 2 sinks in the PA, the one sink has speaker and headphone, the other one has the lineout Supposing users play music via totem (gnome app) and neither front headphone nor rear lineout is plugged, the sound will comes out from speaker. While the music is playing, if users plug a headphone into the front headphone, the headphone will show up in the gonme-sound-setting and the speaker will disappear, and the sound will change to heapdhone from speaker, so the steam auto swtiches from speaker to headphone because both speaker and headphone belong to the same PA sink. But while the music is playing, if users plug a headphone into the rear lineout jack, the lineout will show up in the gnome-sound-setting and the speaker will disappear too, but the sound will not switch to lineout, it keeps staying in the speaker even the UI shows the speaker is relaced by lineout. it doesn't auto switch just because the speaker belongs to one sink and the lineout belongs to the other. When this issue happens, if users want the sound comes out from lineout, users have to close the totem and re-run the toem to make the sound come out from lineout. This is not user friendly. + + And a similar situation is: + users play the music through lineout and UI (gnome-soudn-setting) shows lineout is active, while it is playing the music, if users unplug the headphone from the rear lineout jack, the lineout will disappear from UI and the speaker will show up, but the sound still comes from lineout, it doesn't switch to speaker.
