False, the Google dongle works just fine and other users have reported a higher end FiiO dongle to be working too.I just read through the conversation and it just baffles me. So the "official" Pixel support forum is run by volunteers who basically tell you "if you have a problem, don't bother us, we just give you pre-prepared text-blocks - if they can't help you, we're out" - if you want "real" support, go and use "feedback form" - meaning you write a wall of text to an known person, won't get any sort of answer or input and have to pray that Google will care?
I mean, as a Pixel user you can always try the

form, that way you can at least write to a person/talk to a human, even though they will most likely also just form a "feedback form" after your conversation, since they are powerless Tier I tech people.
I hope that Google can fix those problems here, so you guys can have fun with your device. Google certainly doesn't deserve the "our phone just works" - status, if they forget to add basic compatibility to common third party hardware.
