The actual VISTA Realtek driver did not provided seperate analog and digital Direct Show interfaces, but only one all purpose. Why ever, the Bass Player did not seem to use the digital path but only the analog path. As the driver is also disabling the digital output while an analog cable is plugged you are stuck here. The "Virtual Audio Cable" driver which is establishing a virtual soundcard and enabling re-routing the bass player to digital interface is a workable solution, but needs to be established every time manually. Last resort was to uninstall the Realtek driver and reverting to the original Vista Sound-driver which is providing two distinct direct show interfaces for analog and digital (Disabling also all driver features for sound encoding and manipulation; e.g. only digital stero or AC3/DTS pass through and no processing of 2ch dolby signals via AC3-filter/ffdshow to 5.1 is possible anymore).
