The ID used for detection of the BenQ R55E actually identifies the Quana TW3 ODM design, which is also used for the Gigabyte W551 laptop series. Schematics on the internet clearly indicate that the "Port C" (analog input connected to record source #4 and mixer input #4) is unconnected.
Well, such an action needs to be done carefully since the documentation often lies. But I also doubt that there is any analog CD line. If this is confirmed that actually it's not present on the real machine, fine to remove it indeed.
