Public bug reported:
there is no audio device accessible any more and pulse-audio process can not be
terminated
in kernel log there is such a output:
This makes the complete audio unstable in the laptop.
I think it is started to happen when I installed Nvidia driver and there
is an external monitor attached with DP audio device.
