I installed a Realtek HDAUDIO driver on my sonyVAIO Notebook of model-PCG-7L1M but still no sound is produced.The notebook speakers are workin fine.What should I do?

It would seem that you have the wrong driver installed!!
The driver you need is the Original - SigmaTel® High Definition Audio Device Driver
Which can be found here along with all the other drivers for your laptop!

Good Luck!

No audio device on notebook


Sounds like you indeed have a problem with an audio hardware driver. Presumably the 'Audio Device on High Definition Bus' is the system detecting a device it doesn't have a driver installed for.

First question - was the sound working previously? If so, did you recently install any type of audio software not related to the sound device itself?

Please provide the exact model number of the VAIO notebook and we can point you to the correct driver and try that for starters.
