since no byte-order change needed here, maybe we can make it more explicitly.
+ buf[0] = 0xF8;
+ buf[1] = 0x72;
+ buf[2] = 0x4E;
+ buf[3] = 0x1F;
+ buf[4] = sh_audio->a_in_buffer[5] & 0x7; // bsmod
+ buf[5] = 0x01;              // data-type ac3
+ buf[6] = (len >> 5) & 0xFF; // number of bits in payload
+ buf[7] = (len << 3) & 0xFF;

dts part also make samilar changes, or keep the last one AV_WB16 for
length as you like.

I think AV_WB16 is some kind of implicative way to do what we want, it
even use bswap_16 on little-endian byte-order platform, not directly
just as assigning byte by byte ourselves.
