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.
