That's how the iec958 device is intended to work.
The AES0..3 parameters of the iec958 device are the _only_ way to set
these flags. If you don't set them, they get a static default value;
see <http://git.alsa-project.org/?p=alsa-lib.git;a=blob;hb=HEAD;f=src/conf/pcm/iec958.conf>.
If PA wants to set these flags, it must do so when opening the device;
any other mechanism will not work.

Clemens
