Optical, no.
From ultra q&a

Will it be possible to route multichannel HDMI input to multichannel USB output (e.g., 5.1 channel)

Our system currently supports only two-channel audio for both HDMI input and USB output. However, our team is exploring options to enable multichannel support for routing HDMI input to USB output.

Which is at odds with this one (where I believe it's referringt to a 5.1 signal coming in to the ultra's hdmi port

Will the Ultra support multichannel music output on the HDMI port? If not, thats a big miss for a premium product

Yes, it supports Dolby Digital 5.1 audio.

Yes, it supports Dolby Digital 5.1 audio.

It's pretty Clear that the WiiM FAQ writer was talking ONLY about Multi-channel Input, as Ultra has only HDMI-ARC Input and no HDMI-Out (hence no "multichannel music output on the HDMI port").
And to date, WiiM hasn't given any detail on support for any format but Dolby Digital 5.1; nor any explanation on how 5.1 is converted to 2.0; or if the .1 LFE channel is preserved or if Sub Out on the Ultra and Amp is simply the EQ Lowpass Filter.
