Comment 34 for bug 188972

I observed something interesting. When I hooked up my wireless mic and cranked down the signal to -30db, the sound was not bad - no noise and quite clear.

It would clip the audio if I spoke loudly. If I adjusted the mic level down in the gnome desktop mixer app, it would get quieter but still clip at the same speaking volume.

Thus, there seems to be something limiting the input dramatically. I'm wondering - perhaps the jack is set to be a line in rather than a microphone? I don't see any option to adjust this but I will experiment and keep researching to see. If anyone has any helpful information, I'd welcome it. Thank you.

For reference, this is my card (on my Dell Vostro 1520):
