** 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.
