>Description:
I was trying to use Jabra Evolve 20 USB headset, but unfortunately I couldn't manage to hear any sound from it, I am receiving these two errors on audio play or test
audio1(uaudio0): trigger_output failed: errno=5 
audio1(uaudio0): device timeout

What is more, removing it from USB port or sometimes at the beginning of audio play, it may cause kernel to crash:

>How-To-Repeat:
Connect Jabra Evolve 20, optionally make it as default device, try to play from it - gets device timeout/trigger_output failed errors.

Start playing some video in the browser and disconnect the headset from USB port - system freezes, kernel crashes.

 This issue seems to be fixed in netbsd-current. Jabra headset is
 playing sound on audiocfg test. Removing it during test play causes
 assertion failure in src/sy/kern_subr_psref.c, line 296 (mismatched
 pref target class: 0x0 (ref) != 0xffffede25fb1f7c0 (expected)) though.
