NetBSD arm64 9.99.82 NetBSD 9.99.82 (GENERIC64) #3: Fri Apr 30 00:08:47 IDT 2021 fly@planets:/bracket/obj/sys/arch/evbarm/compile/GENERIC64 evbarm
>Description:
We are attempting to port the OpenBSD uaudio driver.
I did not realize that playback is unsupported and blindly tried to play audio by writing to /dev/audio.
This may be an audio subsystem bug.
This is a pinebook with a Creative BT-W3 plugged into EHCI port.
