[PROBLEM] Kodi randomly hangs while playing audio

[jakenl]

My problem is still there. The weird thing is that playing audio fails all the time, but video's play fine. They are both located on different USB-sticks.

Also, I did 2 things in between multiple 'pull plugs' because xbian hangs/can't be accessed anymore:

Did from SSH a 'sudo reboot'. On the screen I see Kodi closing down and it is showing the Xbian log while saying 'unmounting fs'. However, it stays on that screen forever
After another hang up with Kodi, I checked 'df -h' through SSH, but that command makes Raspbian to fail completely, I can't use the cmdline anymore at all.

So, could be this one USB-stick the culprit? What would be the best method to check?
- Put the stick in a Windows PC and do file check?
- Copy the data-backup on pc to my 2nd stick with the video files and check if it still has issues playing form there?
