NetBSD 8.99.1 (RPI2) #0: Sun Jun 25 04:10:47 UTC 2017 evbarm
The default option of hw.uaudio0.precision is 32 and if I try to use my USB microphone, I'll get the

[oss @ 0x6ce04800] Soundcard does not support 16 bit sample format

message followed by

/dev/audio1: Input/output error
It is a new problem since we have the kernel mixer. I never had this issue before, Maybe everyone can have this issue trying to use their microphone on NetBSD with a command like

ffplay3 -f oss -i /dev/audioX
sysctl -w hw.uaudio0.precision=16

This should be fixed in sources after 20170625 11:00 UTC, as the auto
configuration of sound devices had some issues.  Please try a kernel
from sources after this date to determin if the problem still exists.
