PCM2906 reduce components question

Other Parts Discussed in Thread: PCM2906C, HID2, OPA2353

Dear Sir

We want design pcm2906c and hope reduce components.

we don't need HID function, may we leave HID0/HID1/HID2 floating?

for SSPND pin,may we also folating?

I have check PCM2906C EVB, VoutL/R and VinL/R have connect LPF(OPA2353). If we remove LPF, Is there will have any impact?
