I wanted to ask why is there (here https://help.ubuntu.com/community/SoundTroubleshootingProcedure) in Step 1 lightdm package installed? I believe Ubuntu does not use lightdm but gdm, right?
I cannot modify the page or ask there, so I am asking here...
BTW, and no, following the whole step1 did NOT resolved the microphone-not-working problem :(
