I'm trying to use the Behringer BCD3000 as a sound interface and i'm having some issues. The sound card is detected, and the modules are loaded correctly. I have normal playback with all 4 output interfaces, but the input signals are extremely low.
The problem is that alsamixer says that "This sound device does not have any controls.", and I can't change the volume of the channels. Actually, I don't need to have controls (the device has a hardware preamp), just need the input levels to be audible.
The device works properly on windows, with good input sound, so it seems like a driver issue.
Please, can anyone help me?
Tks!
