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?
Here are the relevant lines from usbdevs -v (debugging enabled for uaudio): Controller /dev/usb0: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), Intel(0x8086), rev 1.00 port 1 addr 2: high speed, power 100 mA, config 1, Schiit USB Audio Device(0x0319), Schiit(0x0d8c), rev 1.02 port 2 powered port 3 powered port 4 powered port 5 powered port 6 powered Here are the relevant lines from dmesg: uaudio0 at uhub0 port 1 configuration 1 interface 0 "Schiit Schiit USB Audio Device" rev 2.00/1.02 addr 2 uaudio_identify_ac: AC interface is 0 uaudio0: audio descriptors make no sense, error=4 uhidev0 at uhub0 port 1 configuration 1 interface 2 "Schiit Schiit USB Audio Device" rev 2.00/1.02 addr 2 uhidev0: iclass 3/0 uhid0 at uhidev0: input=16, output=16, feature=0 ugen0 at uhub0 port 1 configuration 1 "Schiit Schiit USB Audio Device" rev 2.00/1.02 addr 2 Here is the uname -a output: OpenBSD goofy.bunix.org 5.3 GENERIC#0 i386 Kind regards, Martijn Rijkeboer
