** Description changed: - this bug is for tracking purpose. + [Impact] + Users could adjust the speaker's output volume from UI, but the sound + doesn't change with the user's adjustment. + + [Fix] + Backport 2 upstream patches, these patches are merged to 5.8.0-generic + with stable update, but not in 5.6-oem yet. + + [Test] + run amixer contents | grep DAC1, we could see the DAC1 mixer control + is found, adjust the speaker's volume from gnome-sound-setting, then + play some sound, we could hear the sound's volume is changed with our + adjustment. + + + [Where problems could occur] + This could possibly introduce the speaker output doesn't work anymore + on lenovo machines with dual speakers, but this posibility is very low, + I have tested the patches on 3 different lenovo machines with dual + speakers.
