I have a problem where I had working audio the very first time I installed my system, I then installed a graphics card (dell gt640) and now I am unable to get audio.

I have followed the steps in post 1 under the section no audio and am still unable to produce. sound.

my oudio outputs show up in system preferences/sound/outputs as internal speakers, line out, line out, and digital out. I have tried every cobination of line out /internal speaker with both front and back 3.5mm jacks.

at the point I am a bit stuck. I do see something that may be odd.. I have 3 entries for intel high definition audio... i don't know if that is normal...



Description of audio problem, including the following information:
OS X version/motherboard model/BIOS version/processor/graphics

Thanks for any help you may be able to provide...

Graphics card has nothing to do with onboard audio. IOReg shows audio working. How are you verifying sound?

@ Toleda:

with the HDEF inject attached below, now i have audio!
I don't know why...!

Over edited; only layout-id and pinconfiguration injection required; see ML: How to Add or Edit dsdt/HDEF, same for Mavericks.

Thanks for the quick reply, I am verifying the sound using my phone as an audio source.

I then use each of the ports and mute/unmute while playing a song from itunes.

the reason I brought up the video card..I remember once when using windows and I used a display port the audio defaulted to the display port and not the audio out. ... in this case I am using the audio properties under system settings to set the output port...


I will say again when I first built this setup I did get sound. only after putting the video card in did I notice it had stopped working...


thank you very much for any and all help...

OS X has not supported an audio input connected to audio output since OS 9. See Optional Installs/2. Connect Audio Input to Audio Output, Post #1, Mavericks: Audio - Realtek ALC AppleHDA

Like you said in a previous post:

only layout-id and pinconfiguration injection required

I did some tests, and then, I replaced ACPIPlatform x58 Rollback, with ACPIPlatform native 10.9.2 ...
I also added the last injection in DSDT instead of the one I posted previously... and the audio worked again!
I suspect that ACPIP. Rollback is no longer compatible ...
I confirm that boot times are almost identical with the two respective kexts. (unlike ML)
I also added _DSM method under LCPB in DSDT, and the timing of sleep and wake are almost instantaneous.
Even the audio noise is gone after wake.

sorry I am not sure I was clear enough.. I was using my phone connected to the speakers to make sure they were functioning... I then used itunes to sources music to try and test the outputs of the mac.

Do you think I could be trying to use one of the incorrect instances of the audio driver? (it seems there are three settings to try setting 1, setting 2 and setting 3) I do not know how to change the settings to test the other ones...

I will also look around to see if I can find a post that might shed some light on it... thanks again for all of your help...

EDIT:
I was speaking of the audio layouts and I followed your guide to find them in under hdef... I see they are all listed as layout 1 I do see that I have two or three posible Hdef ?? listed @1B @3 and @0,1

I do not know if that is normal or not...
