I need a device that can simultaneously output both TrueHD Atmos AND output a signal to optical out or L/R. The thing that i'm experiencing with all the devices that I purchased so far is that they can't output any sound from TrueHD through either RCA/Optical/3.5mm because it needs digital to analog conversion. I've bought a few devices and all of them seems to be able to convert the audio or passthrough but can't do both at the same time. Can this device do that? HDMI output with TrueHD Atmos AND have that same sound output to L/R out or Optical Out?

Yes, This device is capable of providing HDMI Out with TrueHD Atmos, L/R Out as well as Optical out simultaneously.
