[Abigail101]

Does anybody know if there is a driver upgrade or some other fix that I need to perform.
I have recently bought these Speakers on P505-S8980 and I am trying to setup for my use. But the sound quality of these speaker is very poor; And the problem remains the same no matter whatever is the source of audio. First problem is that the maximum volume is not very loud and the sound which is coming out is not of good quality. The most annoying thing is that there is vibration and distortion occur in the higher audio frequency. Therefore, I need solution for the Harmon/Kardon Speakers on P505-S8980 are putting out poor sound quality

If your laptop uses the Conexant Pebble audio drivers try uninstalling the driver, reboot the computer and let Windows install its own default audio driver. For some who have trouble with sound on laptops that have the Conexant audio driver, removing the driver and letting Windows install the default driver helps fix some of the sound issues

I will also suggest you to use the default drivers of window 7. This may solve your problem. But if it does not solve your problem then download the latest Conexant Pebble driver from the official site. Conexant Pebble and then reinstall it on your Toshiba laptop.

Yes, installing the latest Conexant Pebble driver will solve your problem but you have to take care of certain points, which are mentioned below:
1. First of all make sure that you have updated your window 7 operating system
2. After that go to the device manager which is under control panel
3. Now under sound devices uninstall Conexant Pebble driver
4. Restart you computer and it must work well

Try these step this will definitely solve your problem
First as mentioned in the above reply, download the latest driver from the official site of Nvidia.
After that go to
Control panel -> system/security -> system -> advanced systems settings -> Performance (visual effects, etc) -> settings -> Now adjust for the best performance.
