No sound in Pingus

I downloaded Pingus but alas, no sound. Tried disabling pulseaudio which worked for Outgun, but no luck.

Found this bug listing: https://bugs.launchpad.net/ubuntu/+source/pingus/+bug/571536

1. I tried to install libsdl1.2debian-pulseaudio, said it was already at newest.
2. Installed libsdl1.2debian-alsa, which removed pulseaudio and ubuntu-desktop
3. Disabled pulseaudio (pingus sound worked!), enabled pulseaudio (no sound)
4. Installed libsdl1.2debian-all, which removed libsdl1.2debian-alsa
5. Disabled pulseaudio (pingus sound worked!), enabled pulseaudio (no sound)

A related post that looks promising, but I have not tried it: Elegant solution to disable pulseaudio

Virtualbox KVM error

I installed QEMU, but then a few days later when I tried to run my Virtualbox Windows 7 64-bit Guest, I got this error:

AMD-V is being used by another hypervisor. (VERR_SVM_IN_USE). VirtualBox can't enable the AMD-V extension. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_SVM_IN_USE).

I uninstalled QEMU (as suggested in some of the forums), and tried again but still go the same error.

Then I found this command which worked. However, it is temporary and you'll have to run it after each reboot.
sudo rmmod kvm_amd kvm
Next I found this code, which also worked but would have to be run after each reboot.
sudo service qemu-kvm stop
But... why should I be disabling a qemu-kvm service when I supposedly uninstall QEMU???

I checked services but could find not find an entry for qemu-kvm. After doing a system search for qemu-kvm, I found this file:
/var/lib/update-rc.d/qemu-kvm
I moved the file to my home folder, rebooted, and now my 64-bit Guest OS's are working again :)
