    ALSA: usb-audio: correct M-Audio C400 clock source quirk · 2aad272b
    Eldad Zack authored
    Taking another look at the C400 descriptors, I see now that there is
    a clock selector (0x80) for this device.
    Right now, the clock source points to the internal clock (0x81), which
    is also valid. When the external clock source (0x82) is selected in the
    mixer, and the rates mismatch (if it's free-running it is fixed to
    48KHz), xruns will occur.
    
    Set the clock ID to the clock selector unit (0x81), which then
    allows the validation code to function correctly.
