The symptom I saw using a PPC Linux frontend to a x86 Linux backend was the audio sounded like static. The video worked.
Thanks for that additional information, Taoyama-san. Working video means that your frontend was compiled with -DWORDS_BIGENDIAN
If it still has static for audio after a recompile, could I trouble you to try these changes:
