I am not sure if this will help, but you are senting the AC3 PID as
audio PID. The routines that I adated from vdr are getting the AC3 PID
in a different position. Since AC3 is represented differently in the PMT
setting it as audio PID will probably result in a faulty PMT that is
send to the CAM.
You will either have to write a dvbrc that contains the channel
informatio including the AC3 PID, or you need to add an option to
cam_test to set the AC3 PID in the command line.
