intel HDA no sound

[openbysource]

Hello friends,

 

I have a sound card of soundmax integrated Digital HD (High Definitaion Audio).

 

My vendor ID = 11D4

My Device ID = 1986

(These are soundmax codes).

 

 

My vendor ID = 8086

My Device ID = 27D8

(These are Microsoft UAA High Definitaion Audio codes).

 

I did the following:

 

sudo su -

rm -rf /System/Library/Extensions/AppleHDA.kext

vi /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/Info.plist

 

and wrote

<key>IOHDAudioCodecVendorID</key>

<string>0x11d41986</string>

 

save and exit.

 

Then

 

vi /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist

 

and wrote

<key>IOPCIPrimaryMatch</key>

<string>0x27d88086</string>

 

save and exit.

Then I did

rm -f /System/Library/Extensions.kextcache

rm -f /System/Library/Extensions.mkext

kextload -t /System/Library/Extensions/AppleAzaliaAudio.kext

kextcache -k /System/Library/Extensions/

 

Then a reboot.

 

After that I went to

Finder > Applications > Utilities > Audio Midi Setup.

 

There I saw Output device as Intel HD Audio. Ok I made the volume maximum closed it and played a mp3 in iTunes. It played but no sound came out of my laptop speakers. I tried with earphones too in line jack and headphone jack (I only have these 2) but no sound came.

 

I am able to play mpeg, dat, avi, mov, mp3 all but no sound is coming out.

I have SoundMax Integrated HD Audio (Lenovo 3000 N100 Laptop).

 

And have ICH7.

Also installed version of OSX is JaS 10.4.7 (SSE3 Patched).

 

Any more information regarding my hardware details ?

 

Please help

Try pluging your speakers into the other jacks (pink & blue).

Nothing else

Try plugging it in the Mic Jack

There is no sound in jack connectors or speakers

Thanks
