Sound Problems Fedora 16

Hello Team

Getting a strange problem in that sound works from within my host OS (Fedora 16 64bit)
I boot up my VM (VirtualBox) and sound works fine in the VM and on the host
After a period of time sound stops working in the VM (could be a couple of hours)
I drop back to my host OS to test the sound from there...and this is where it gets interesting
1. When I change the volume from the desktop I here no alert sound (ping bark, drip...whatever)
2. If I go into sound setting and change the volume I can hear the alerts
3. Other than the changing volume from the speaker icon on the desktop sound work fine from the host OS but nothing in the VM?

This is pretty much a standard out of the box fedora 16 install with Gnome 3 as the desktop.

I am sure that this has nothing to do with it but I am running the host OS from an external hard drive to test before I upgrade from Fedora 14 to 16. Also migrated off of VMware to Virtualbox to host my Windoz work instance.

Thanks for your help team

Stu

Re: Sound Problems Fedora 16

I'm not an expert on Fedora audio, but in trying to solve a problem with my own FC 16, I came upon this thread: https://bbs.archlinux.org/viewtopic.php?id=90700. The last post in it recommends the use of the command "fuser" to investigate an audio problem. I don't understand the output of fuser yet but you might try it before the problem starts and after to see if something changes. Perhaps someone will tell us what it means.
