No Sound on Yosemite with ALC 898!


12 posts in this topic

 I have tried everything I know to get my sound working, but no good. I am using clover R2953 (Latest). My kext is ALC 898. Is the only way to get back to the native kext for Apple HDA to install Yosemite again? I would rather not do that as I have now finally got Imessage working.  I am not using a DSDT. Any suggestions would be a big help.

Thanks for the response and advice Mirone.  I went ahead and added into my config.plist.  I also added in your kext AppleHDA-266.5-ALC898. However there is still no input and output showing for my Audio.  What else should I try.  

 

<key>Audio</key>

<dict>
<key>Inject</key>
<string>9</string>
</dict>
 
What does it mean when it says "AppleHDA.kext has invalid signature; omitting"  When rebuilding Cache using chris1111 install kext Yosemite?

Mirone - Thanks for your help and everything solved once I entered kext-dev-mode=1.  If you could answer one last question for me that would be great.  I am booting off my GTX 760 GPU and using HDMI Audio.  I really miss not being able to control my volume via my Mac Wireless keyboard as I am not plugging into IGFX and using my HD4600/built in Line Out Audio ports.  What are my options. Is it basically choosing my GTX 760/HDMI Audio/No Mac Keyboard control for Audio or HD4600/Line Out Audio/Mac Wireless Keyboard working.   Appreciate anyone's input on slightly off topic question.

Thanks for the reply!  That means I must be doing something wrong.  When I boot with IGFX and plug in HDMI via Mobo - I can use the analogue out port on Mobo and get sound working. Once I change to connecting via my GTX 760 (PCIe as 1st boot), the same Audio Analogue out port does not give me sound.  Is there something I am doing wrong or is this not possible.

As you do not use a DSDT in its config file you must inject the ID of your onboard Audio card.

<key>Audio</key>
<dict>
<key>Inject</key>
<string>9</string>
</dict>

use my kext to yosemite, ALC898.

 

Hi Mirone,

 

I have the same problem and I'm asking you where I can find your kext.

 

Thanks and have a nice day ;).

S.

 

EDIT: I found it: AppleHDA-267.0-ALC898.zip 

 

Do I have just to install this with Kext Wizard and then to add that to Clover?
