** Description changed: - If the output devices are on different sinks, PA can't auto switch - streams on them + 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.
