Mavericks 10.9.1 Update and Audio Always WORKING??

[Deleted member 188658]

10.9.1 Update went successfully.

I have audio through HDMI to my ASUS display with speakers. This continues to work without having to do the Multibeast v6.0.1 audio driver re-install. I do see that AppleHDA.ext has been modified by the 10.9.1 update.

What am I loosing or missing by not doing the Multibeast re-install? Is it audio out through the MB speaker connections?

Can anyone clarify the TRIM enable for me too? Doesn't 10.9.x have native TRIM? Why should I install the TRIM from Multibeast?

I posted above questions to the general FAQ on Mavericks 10.9.1 Installation. I haven't got an answer to the questions.

Let me ask this again.

I have done the 10.9.1 Mavericks update on the two Hackintoshs I have built, both of which use HDMI Audio out to my display+speakers. I followed Toleda's excellent guides on how to do this and completed a full DSDT patch/hack to make it work.

Why is it that in neither case of the updates I didn't have to use the Multibeast 6.0.1 to re-install the AppleHDA.kext, which I can see the 10.9.1 update changed? Is my audio using a different kext?

One system can be seen in my Signature, the second is an older Ivy-Bridge H67 Gigabyte Motherboard. As I said, both Audios continue to work flawlessly after the update. I just want to know why. Maybe this information can help others too.

HDMI audio works with the native AppleHDA.kext. Any DP port is supported natively. All but 3 Nvidia GeForce graphics cards since GT 4xx natively support HDMI audio in 10.8 and 10.9. Many HD3000 and HD4000 systems are supported natively. On the other side, only a few specific AMD graphics cards (manufacturer and model) and no HD4600 system support OS X HDMI audio natively.

Assuming onboard audio is not required, selecting the right components ensures HDMI audio works with the native AppleHDA.kext.

Toleda:

Many many thanks for your diligence in general and this reply in particular.

I hope this helps others to see the connection between the proper Graphics choices and native working Audio.
