bq aquaris 4.5 and mini dac support

This is a reply to my question here https://forums.ubports.com/topic/4872/usb-dac-and-bq-4-5
I'm starting a new message so it can be categorized appropriately.

Looks like I answered my own question. I tried a usbc dongle dac plugged in to a usbc to micro usb adapter and when it's plugged in to my phone, the audio is not routed through the plugged in dac. Using dmesg I get the following:

usb 1-1:New high speed USB device number 7 using musb-hdrc
input:Generic TX 384kb Hifi Type-c Audio as /devices/platform/mt_usb/musb-hdrc.0/usb1/1-1/1:1.2/input/input10
hid-generic 0003:0BDA:492F.0006: input: USB HID v1.11 Device [Generic TX 384kb Hifi Type_C Audio] on usb-musb-hdrc.0-1/input2

Looks like this has no chance of working?
