Here is lenhart's answer from the pulseaudio development team and my response. This is my take on it all.

I understand this but this isn't about adjusting alsamixer -c0 or pavucontrol. These are maxed out and the recording is very soft (indeed it doesn't matter what setting one uses for a digital microphone it has no effect). Rather there seems to be something wrong with the communication between alsa-lib and pulseaudio. -- internal mic capture very low volume when routed through pulseaudio https://bugs.launchpad.net/bugs/275998 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
