I am facing a wierd issue between my sound card driver and Windows7(any edition). I have a sony vaio notebook (VPCEB24EN). Two days ago, on start I got diabled wifi, charging and speakers. Then I restart the PC and everthing worked fine. Later on I again restarted my machine, and then I found the my speakers were not working. I thought, restart will work. I restarted many more times but it did'nt work. I searched google and found that , it might be due to : 1. Hardware is not switched on from bios. 2. No hardware. 3. overriding 64-bit drivers with 32-bit drivers.

To make it working, I restored my laptop from scratched, but while restoring pc, the realtek HD drivers, it gave me an error 505. I then formatted the drive and installed Win7 Ultimate 32bit (With PC was, Win7 64-bit Home Basic). I got lots of yellow exclamation in device manager, thinking now this will resolve my issue. But Even after the installing all drivers on a fresh installation, I was still with the same position.

A red cross on speaker- No Speakers or Headphone plugged in.

Please Note:

  1. My Laptop is Vaio , E Series, VPCEB24EN.
  2. Audio : Intel® High Definition Audio compatible but accepts Realted Audio. While using BIOS Agent, I got Intel Chipset 5 Series Audio Adapter and ATI RV370 Audio adapter found on my board.
  3. Installed is Win7 32bit Ultimate. factory default was Win7 64-bit Home Basic
  4. Memory: RAM 3GB/ 320GB HDD
  5. Display : ATI Mobility Radeon™ HD 5145 Graphics

I have the same problem and not sure if it's a hardware(audio board) or cable issue. Does your faulty FFC cable allow a USB or external USB sound to work when plugged in? – user132823 May 7 '12 at 21:05
I am not sure about the USB Audio, but my USB pendrives were working fine. When the show me the FFC cable,i noticed that few fine metallic lines were damaged.. – Amit Ranjan May 8 '12 at 17:38

I did that too, My hardware is detected and it accepts only Windows Generic Driver. Any other driver or codec from realtek is not accepted. – Amit Ranjan Mar 19 '12 at 9:22
