>Description:
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
>How-To-Repeat:
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
>Fix:
sysctl -w hw.uaudio0.precision=16
