I've noticed this problem 2 or 3 times now in Virtualbox 3.2.8 running recent revisions including 38589. (The first time or two it was right after installing, and I thought I'd messed up the install, so I just reinstalled and it coincidentally worked again.) This time the sound was working and then stopped. Eventually the sound came back on, but it persisted through 2 restarts. I'm not sure if it was just an odd virtualbox bug, or the same bug you're having trouble with. I was playing an audio track fine, then it stopped working when I tried to play a video... I tried the audio that I'd just been playing, and it didn't work. I checked the volume etc... restarted... still nothing. Restarted again... still wasn't working, but then a minute later it just came back on again (I had the audio playing but no sound was coming out... then the audio suddenly resumed). I don't like testing in virtualbox because I'm always unsure of whether the problem is with Haiku or with Virtualbox, but until my Wifi works again, I don't have much choice.
