well, you sorta can. The major problem with all of this is that the market hasn't caught up with the need yet so it might be a bit until we get something good but there is a solution:
currently I use:
(USB C to USB 3.0 Hub, ARKTEK Type C (male) to USB A 3.0 (female) with Type C (female) Charging, 4-in-1 Hub Adapter for MacBook Series Chromebook Pixel and more (Aluminum, Silver)) - From Amazon (Canada)
and
(TROND AC2 Aluminum USB Audio Adapter with 3.5mm Stereo Headphone/Speaker and Mono Microphone Jacks ) - From Amazon (Canada)
(just google the links, can't put them in here
)
... that I've hooked up together in order to get digital audio out, as there's no available solution for this yet besides the moshi cable from google (part of the reason why I can't go for that is price and that its not available in Canada -.-). I've tried other splitters from various places that claim to do this but they don't work with the pixel, so this is your best bet. in the process of trying to use a USB-a male to USB-C female adapter (also from Amazon Canada) to skip the adapter and try to use the headphone dongle that came with the phone to see if that would work, ill try it and update afterwards.
*edit: forgot to mention, if you do use this setup you have to go to developer options > select USB configuration > audio source for it to work
