audioquest dragonfly not connecting with alsa

Hi.  I have a ?Dragonfly Red which is supposed to be a USB dac, and I
am unable to connectit with alsa.  Its seen by the system and here is
what I get for the card under Alsa:

 1 [v10            ]: USB-Audio - AudioQuest DragonFly Red v1.0
                       AudioQuest AudioQuest DragonFly Red v1.0 at
                       usb-0000:00:14.0-10.2, full speed

But if I try to use something like mpv to play anything with commands
such as

mpv --audio-device=alsa/usbstream, the system comes back with invalid
type for card.

If I do aplay -l I get for the card:

card 1: v10 [AudioQuest DragonFly Red v1.0], device 0: USB Audio [USB
Audio]
  Subdevices: 1/1

So, how would I even designate the device and how would I get alsa to
play it -- there is no volume control on the device which makes it
even more complicated.

Thanks in advance for any suggestions.
