I recently installed OpenBSD 6.1 on my Lenovo ThinkPad x250. I use a USB DAC to listen to music because the built-in laptop audio is terrible.
OpenBSD appears to detect the USB audio device, but is unable to play any sound through it. I've seen similar posts on this list regarding USB 2.0 audio devices and various internal USB hub combinations causing issues, and I'm wondering if this device + laptop combination is a lost cause? Here's what I tried: $ mplayer beep.wav # I hear a beep from speakers # plug in USB DAC, it appears to be detected $ usbdevs addr 1: xHCI root hub, Intel addr 5: AudioQuest DragonFly, AudioQuest inc. addr 2: VFS5011 Fingerprint Reader, Validity Sensors addr 3: Bluetooth, Intel addr 4: Integrated Camera, J8AECPB08 addr 1: EHCI root hub, Intel addr 2: Rate Matching Hub, Intel $ mplayer beep.wav # I hear nothing $ dmesg ... uaudio0 at uhub0 port 1 configuration 1 interface 0 "AudioQuest inc.
