Hi
I just came across a sound booster tool that does an incrdible job on my Vaio SZ. It's meant for Toshiba Notebooks but works on others too if they have a supported sound chip. These are:
ac97intc - Intel® 82801CA/CAM AC'97 Audiocontroller
aeaudio - Analog Devices AC'97
AEAudioService - Andrea Audio
allegro - ESS Allegro PCI Audio (WDM)
ALCXWDM - Realtek AC'97 Audio
cs429x - Cirrus Logic Crystal WDM Audio Codec
es1969 - ESS ES1969
IntcAzAudAddService - RealTek HD
maestro - ESS Maestro
smwdm - SoundMAX Integrated Digital Audio
stac97 - Sigmatel STAC 9750 AC97, Sigmatel C-Major Audio
sthda - SigmaTel HDA
VIAudio - VIA Technologies Implended Audio in the Southbridge VT8237
WDM_YAMAHAAC97 - Yamaha AC97

Install it, reboot and you'll get a new tray icon. You can do incredible things with the small notebook speakers. I was shocked how good they can sound. And it works everywhere (games, media players etc)!
