I just installed Windows 7 on my TOSHIBA M500 PORTEGE laptop and by default it had an Integrated HD audio driver installed but I couldn't get any sound from the speakers or headphones.

Now I've downloaded and installed the Vista Soundmax driver from but still no luck. As far as the system is concerned the driver is working perfectly and when i try to update the driver it says the latest version is already installed.

I've tried several different drivers such as realtek, sound blaster, sigmatel etc. but so far only Soundmax driver was successfully installed.

what is the exact model for your laptop?

It's PPM51L-01800H


I've found the solution

I re-installed XP yesterday to see if I could find anything helpful, and I did! In the device manager I found a device call "modem for high definition audio". I went back to Home | Toshiba Leading Innovation - Asia and found a vista modem driver for my model, so i downloaded it, re-installed Windows 7, installed the driver and it works perfect! :D
