>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:
uvm_fault(0xffff981a31ae1188, 0x609ed000, 1) -> e
fatal page fault in supervisor mode

>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.
