[Bug 1060053] [NEW] Audio starts working several hours after starting Windows Vista guest

[Dirk Heinrichs]

Public bug reported:

since some time now, I have a very strange problem with audio output on
a Windows Vista guest. Right after booting the guest, audio output does
not work (that is: I can PLAY audio, but can't hear anything, although
volume is at 100%). If I leave the guest running for some hours (don't
know how many, I usually try again next day), audio output starts to
work just fine.

I'm using es1370 emulation, but I get the same results with the other
alternatives, too.

Guest: Windows Vista SP1 32bit

Host: Ubuntu 12.10 64bit
