[linux-audio-user] Delta 1010LT Preamp Gain

[Paul Perkins]

I can tell you that there are old fashioned physical jumpers on the Delta 
1010LT card that you are supposed to set one way for line-level and another 
way for mic-level input. One set of jumpers for each of the two lines that 
have mic pre-amps on board.
