Comment 24 for bug 519066

@KaGeN101: The way to compare with older functioning releases, is to do a git bisect - and on my TODO list is to learn how to do that, so I can then teach you others how to do it yourselves :-)

@Gargoulf, hmm, it could be that you must also stop pulseaudio first. https://wiki.ubuntu.com/Audio/StopPulseaudio

@John Castello, Ameet or Ansour, when you have successfully issued these commands and mic is still not working, can you please attach alsa-info information to this bug? Thanks. https://wiki.ubuntu.com/Audio/AlsaInfo
