http://unix.stackexchange.com – I'm try to install blender in my Xen guest (Debian Wheezy), and when I try to start the render blender file via command line, the console shows this: $blender -b CarPark.blend AL lib: UpdateDeviceParams: Failed to set 44100hz, got 48000hz instead read blend: /mnt/shared/drqueue/tmp/CarPark.blend AL lib: ALSAProc: Wait timeout... buffer size too low? Blender quit Any idea how to solve my problem? (HowTos)
