so it's right write?
- HDMI passthrough( RAW ) 7.1: DTS-HD MA, TrueHD, ATMOS, DTS:X.
- HDMI bitstream( PCM ): 192Khz Flac.

PS: DSD is support by USB dac but it's other story.

I don't have a problem when some one says PCM is a bitstream, but most consumer AV devices make a distinction between bitstream (no decoding at source) vs PCM (decoded at source). So HDMI bitstream (PCM) may still be confusing. It is better to say that FLAC is decoded to PCM 16/24-bit 48/96/192 kHz.
