You've got 3 separate audio devices, azalia0, azalia1 and uaudio0.
azalia0: probably HDMI audio which isn't supported yet AFAICT
azalia1: on-board audio detected as audio0, sndiod normally attaches to this
device so all audio played on your systems is played through that.
uaudio0: your USB "Tiny-in-One 23" device, sndiod doesn't attach to this by
default.
To make sndiod use both devices you can add a line to your rc.conf.local:
sndiod_flags="-f rsnd/0 -f rsnd/1"
where rsnd/0 represents audio0, exposed as snd/0 by sndiod, and rsnd/1
represents audio/1, exposed as snd/1.
Specifying either snd/0 or snd/1 in your application determines which device
the audio is played on.
If you want the USB device to be your default device you could try swapping
the parameters:
sndiod_flags="-f rsnd/1 -f rsnd/0"
If that doesn't work, try:
sndiod_flags="-f rsnd/0 -f rsnd/1 -s default"
I hope this helps.
