Re: uaudio0: audio descriptors make no sense, with Schiit Bifrost USB DAC
If I'm interpreting this correctly your device is an USB Audio 2.0 device. AFAICT there's currently no support for such a device in OpenBSD. I didn't know it wasn't supported, so thanks for the info. But it shouldn't be too hard to port the FreeBSD changes in our tree, if anybody is motivated ;) Well I guess that anybody should be me, but I don't have the needed kernel / device skills nor the time to learn them, which will probably mean nothing will change in this area.

uaudio0: audio descriptors make no sense, with Schiit Bifrost USB DAC
Hi, I have a Schiit Bifrost USB DAC that includes an uaudio device for audio playback. When I plug the device in I'm getting uaudio0: audio descriptors make no sense, error=4. Any suggestions on how to make this work?
