I guess you have no build environment so I have compiled it for you.
Make a backup of this file /usr/lib/gstreamer-0.10/libgstdvbaudiosink.so !!!
Then unzip attached file and overwrite existing libgstdvbaudiosink.so in directory /usr/lib/gstreamer-0.10/
At best also delete this file /home/root/.gstreamer-0.10/registry.mipsel.bin
Then restart or reboot box and test.
If it works, every update can overwrite the file and you have the same problems again!
