Resolution Note:
Solo and mute only mute the incoming AudioSources by routing these to an internal mute group, but not affect other signals flowing through. Thus it is muting more on a logical level to filter out specific types of sounds rather than mix buses.
If soloing mutes all other channels except one, it is necessary to keep the other channels "open" in the sense that they still run all their effects and apply for instance echo or reverb on signals received from the solo'ed channel. This is the reason why mute only works logically on incoming channels rather than topologically on the signal flow.
