Sure you are using the latest and greatest alsa-lib? course: "ac3play: 
Unable to update the IEC958 control: No such file or directory", should 
not happen.

The only period sizes supported by the cs46xx hw are:
     2048 bytes
     1024 bytes
       512 bytes
       256 bytes
       128 bytes
         64 bytes
         32 bytes
Try check which period size the programs wants, as something related to 
the period_size seems to be the problem.

Should work fine with xine, almost as it is, out of the box without any 
special configuration.
