Status in “alsa-driver” package in Ubuntu:

Bug description:
everytime i want to use the onboard microphone ,it needs to open the
alsamixer so as to change the volume either more loudly or less and after that
it needs to open the pulseaudio in order to choose the right device.Then it
could work.However .if reboot the systemm ,i should repeat this procedure.
