This controls the digital capture gain from the EMU-1820m card. There is also a mixer control called DSP0 and DSP1 on the playback view. (should be in the capture view, but alsamixer has a bug) Adjust them to the Mic A input. then arecord -fdat -Ddefault test.wav should capture some sound from Mic A.
