FYI,
Sound volume is very low. After suspending, the sound volume returned to normal
status. Then after i reboot, the sound turn to very low again. When running
ubuntu in virtualbox vm machine and choosing " ac'97" as the sound option, the
sound volume is normal and it has no sound at all after switching into "intel
HD-audio" as the sound option.
