Hi everybody! I've just started looking at ALSA because I want to get the mic working with my Asus Xonar U7. Some of you might have seen me on IRC as johanar.

I'm wondering about check_input_term(...) in sound/usb/mixer.c, which for case UAC_INPUT_TERMINAL and UAC_VERSION_2 will recursively go into the clock source. Is this correct behaviour? For my card both mic and line will show up as "Unit 22" when I call "amixer contents" since the two inputs have the same unnamed clock source (they also share physical connector). However, if I comment out the recursive call they show up as "mic" and "line" as they're supposed to.

Btw, if this is correct, couldn't we set id = d->bCSourceID and break; in the same way that case UAC_FEATURE_UNIT does?
