Bug Description
[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-
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.
