Audio problem

1 post in this topic

Recommended Posts

Hi everybody,


I have installed Lion and have updated it to version 10.7.5.



My computer:

  • CPU: Intel Core i7-3820 3.60Ghz Box Socket 2011
  • Motherboard: Gigabyte GA-X79-UD3
  • Nvidia GTS 450

This motherboard use realtek 898 codec.


Sound was not working so I did:

  1. Install 898 realtek drivers
  2. Create my own DSDT and added HDEF

Sound still doesn't work. -> NO SOUND DEVICES DETECTED (DSDT loads correctly)


So I tried something different:

  1. Install VoodoHda 0.22
  2. Removing AppleHDA and HDAenablers
  3. Fix permissions
  4. Restart

After this, sound devices are being detected and I can hear sound when I play songs. The problem there is a hard noise everytime play something. I also checked MIDI configuration and it seems to be OK.


Does somebody know why VoodoHDA works and AppleHDA with the correct HDAEnablers for my motherboard and codec realtek 898 does not? And how could I erase this disturbing noise?

hi, it's useless trying to bypass the forum filters. if they are in place, it's for a good reason.
