i've got Ubuntu Precise ( 12.04.2 ) running via VirtualBox on Windows 7 host machine ( both 64 bit systems ) - intel i3 2350m with 4GB of RAM - 1.5 GB allocated to Virtualbox.
All multimedia played on Ubuntu is very slow and what is most disturbing - audio is played in very weird way - bassy , sound like alien :(
VirtualBox uses WindowsDirectSound ICH AC97 , 32 Megabytes of Video memory ( intel hd3000 )
any ideas how to fix it ?
--edit Install also lubuntu 12.04 , same problem
