It seems this device does not exist from the kernel's point of view.
(there's also /dev/audioctl1, but using that probably doesn't make a
difference)
I think there should be some controller that you configuring the audio
device. But i manually tried to change the symlinks in the dev directory:
# ls -la * | grep -E "mixer|audio"
lrwxr-xr-x 1 root wheel 6 Jun 3 16:58 audio -> audio1
crw-rw-rw- 1 root wheel 42, 128 Jun 3 17:01 audio0
crw-rw-rw- 1 root wheel 42, 129 May 28 19:07 audio1
crw-rw-rw- 1 root wheel 42, 130 May 28 19:07 audio2
lrwxr-xr-x 1 root wheel 9 Jun 3 16:58 audioctl -> audioctl1
crw-rw-rw- 1 root wheel 42, 192 May 28 19:07 audioctl0
crw-rw-rw- 1 root wheel 42, 193 May 28 19:07 audioctl1
crw-rw-rw- 1 root wheel 42, 194 May 28 19:07 audioctl2
lrwxr-xr-x 1 root wheel 6 Jun 3 16:58 mixer -> mixer1
crw-rw-rw- 1 root wheel 42, 16 May 28 19:07 mixer0
crw-rw-rw- 1 root wheel 42, 17 May 28 19:07 mixer1
crw-rw-rw- 1 root wheel 42, 18 May 28 19:07 mixer2
But it is still defaulting to my builtin soundcard. How can i change the
default sounddevice from audio0 to audio1?
I think using sndiod(1) is the answer, in the most simplistic form,
something like this in your rc.conf.local(8) should suffice:
sndiod_flags="-f rsnd/0 -s onboard -f rsnd/1 -s default"
This should make your audio0 device available as "snd/0.onboard" and your
audio1 device as the default sound device. (Both should be available as
"snd/0" and "snd/1" respectively as well IIRC).

uaudio0: ignored setting with type 8193 format
If I'm correct format 8193 (== 0x2001) means "IEC1937 AC-3".
This is an encoded format. AFAICT the uaudio driver only supports plain PCM
formats. ("unencoded" audio samples)
Do you know if your device only supports AC-3 inputs or can it also handle
PCM signals ?
(running 'lsusb -v', from the usbutils package, on the device should give a
good clue what your device supports)

I can successfully run this command:
if i use audioctl1 instead of audio1 it works, i dont know why tho.
