External DAC / sound card in OpenBSD

[Os Miridium]

Hi there,

fairly recent OpenBSD convert here after a decade on linux. I must say I am pleasantly surprised how often I can just do what "feels like it should work" and it actually works. Nice. However, I still have some things to work out.

I am now trying to connect a Focusrite Scarlett 2i4 USB DAC to my OpenBSD system to use as an external sound card. From what I have figured out so far, it seems I need to point an audio "device" (probably audio1) at the one of the stereo output channels of the Scarlett. If I understand these two correctly, the interface should show up in dmesg as connected to audio1 with a line like:

audio1 at uaudio0

There is no such line in my dmesg. It seems like this might/should happen automatically or can be done manually. My question is, how do I make it so?

Here is my $ dmesg | grep audio

audio0 at azalia1
uaudio0 at uhub0 port 4 configuration 1 interface 0 "Focusrite Scarlett 2i4 USB" rev 2.00/1.25 addr 3
uaudio0: audio descriptors make no sense, error=4
uaudio1 at uhub0 port 4 configuration 1 interface 3 "Focusrite Scarlett 2i4 USB" rev 2.00/1.25 addr 3
uaudio1: audio descriptors make no sense, error=4
uaudio0 detached
uaudio1 detached
uaudio0 at uhub0 port 4 configuration 1 interface 0 "Focusrite Scarlett 2i4 USB" rev 2.00/1.25 addr 3
uaudio0: audio descriptors make no sense, error=4
uaudio1 at uhub0 port 4 configuration 1 interface 3 "Focusrite Scarlett 2i4 USB" rev 2.00/1.25 addr 3
uaudio1: audio descriptors make no sense, error=4

azalia1 being the internal sound card.

I did not find a solution (or did not recognize it as the solution) in the man pages of sndio, sndiod, audio, audioctl, or mixerctl. Where else did I miss to look?
Any help would be greatly appreciated.

Thanks,
Os
