Description lemniscattaden 2017-01-03 15:43:40 UTC

When I connect my Fiio X5 II as external DAC to my PC PulseAudio hangs (unkillable). Google knows about this bug (https://bbs.archlinux.org/viewtopic.php?id=202648 http://forum.ubuntu.ru/index.php?topic=263700.0 https://ubuntuforums.org/showthread.php?t=2274844). The same problem with Fiio X3 II. People says that problem assigned with xhci. I can't check this because my motherboard doesn't support xhci disabling.
Fiio works fine without PulseAudio, through ALSA.

Dmesg log from forum (on my system I saw something similar):

This seems like a kernel bug, since dmesg shows a kernel stack trace and pulseaudio becomes unkillable. Those two things should never happen on a good kernel. I understand that you'd like to blame pulseaudio on the basis that you can use the card without pulseaudio, but pulseaudio can't be blamed for kernel bugs.
