Hi Raphael, Thank you very much for your answer. Do you mean, that you can change the levels via the adc faders? Because I cannot find a switch +4 or -10 in the 5th tab. And thank you for your tip with the alsamixer. It shows me, that for the adc fader in envy24control set to 124, I have 0 gain. Alsamixer says that it can change the volume between + 18 db and -62 db, can we trust these values? Still, the range from 0 to 163 in envy24control seems strange to me... In terms of sound quality, is it bad to amplify the input signal via the Delta1010lt (with adc set higher than 124)?
