    I think I've gone through every possible value here from asound.state to
    each setting in KDE itself. Still, the only sound that works is the one
    coming from line-out, without the port replicator, no sound exists
    whatsoever. Both of the below controls are set to false in asound.state
    and cooresponding KDE settings in kmix.

    I think the concern becomes though, regardless of what kde was doing after
    the fact, this condition didn't exits in <= 2.6.10 when no other
    applications where changed around it.
