My problem is that PulseAudio don't register input level from some of my input devices.
When I speak in my mic the input level in PulseAudio don't show any reaction!
They are not muted and volume is near 100%.

- These mic devices don't work:
Built-in mic give no input level (internal speakers output works fine).
External mic give no input level (external headseth output works fine).
USB Sennheiser 3D G4ME1 + Sennheiser PC 363D mic give no input level (headseth output works fine).

- These mic devices works fine:
USB Jabra Speak 510 mic gives input level (output also works fine).
USB Plantronics C720 mic gives input level (output also works fine).
