Sound disappears in Windows 10 guest on Windows 10 host

[boxer01]

It’s addition to the ticket #15200. After updating to the 5.0.16 the sound first disappears on the 19th March 2016 after the host overnight hibernation. Next time, at the 29th March 2016, on the current 5.0.17 build, sound disappeared on the running guest. After using for a while I suddenly realize, that I didn’t hear any system sound for a while. After sound checking I saw, that the sound didn’t work in the whole guest, but there was no problem with the host’s sound. So the case is little bit different then the three previous ones.

P.S.: Why I can’t change some fields of some ticket created by me? I mean it should be possible for the original reporter to change description, version, component or host or guest type? Just because I can’t change version of the previous ticket and extend the description, I am forced to create a new one for nearly same bug.
