Most often, even wahat you consider "high end" cards do not have the audio
sheild grounded properly.


Very good point. Some cards have shield connectors that are DC
isolated from the chassis to prevent ground loops with other audio
equipment. In such cards the shield is coupled to chassis ground with
caps, but line noise can be a problem (and the cap must be shorted)
because the caps may not large enough to fully shunt low frequencies.
But the caps do shunt RF very well, and if they can keep the local AM
broadcast stations out of the soundcard then the neighbor's legal CB
radio shouldn't be a problem.
