This sounds like a bug in alsa-lib mixer abstraction. There is a known shortcomings in the "capture source" enum, e.g. it can't take more than one ADCs. > This happens with both the patched hard-coded "BenQ" configuration and > the auto configuration. OK, I'll check it in the next week. thanks, Takashi
