I've recorded cards internal noise(signal) - without any mic/line plugged in.
Parameters: 100% rec volume, AGC: Disabled

I'm wondering if its normal for this sound card to have so much internal noise, or its just my faulty unit?
Blinking LED is introducing great amount of "signal", is there any way to disable/enable it permanently?
