Description (last modified by )
Hello,
In VirtualBox 2.1 and 2.2, VBoxSVC.exe uses 100% of 1 CPU core. I'm also using an external USB audio controller, which seems to be correlated with my problem. I read here (http://forums.virtualbox.org/viewtopic.php?p=23861) that 100% CPU utilization may result when another program using sound is running when a VM is started.
Configuration:
- Intel Core 2 Duo
- VirtualBox 2.2.2 r46594 win.amd64
- host: Windows Vista 64-bit Home Premium SP1
- guests:
- 32-bit Windows XP Pro SP3
- 32-bit Ubuntu 8.10
- C-Media CM106 USB 3D audio controller (Toshiba Dynadock)
Matrix of scenarios that I've tested:
scenario | guest VM | USB audio | VBoxSVC.exe |
1 | on (WinXP or Ubuntu) | on | 100% CPU |
2 | on (WinXP or Ubuntu) | off | normal |
3 | off | on or off | normal |
A typical scenario is the following: USB audio is active; I start VirtualBox and power on my virtual machine (WinXP), and VBoxSVC.exe is running normally. As soon as I open the Zune player or go to Pandora.com, VBoxSVC.exe starts using a full CPU core, and will not stop, even after I exit my music player.
I'm using a Toshiba Dynadock docking adapter which has the USB audio chip. It seems that this VBoxSVC.exe issue disappears when my PC is not docked to the Dynadock.
