Hi, my internal mic is not working on my Acer V5-171, speakers and headphones are fine.
The sound card is an ALC 269 and I am using HDA, HDAEnabler and IOAudioFamily by AmeerSaeed. I think my DSDT needs an edit but I've not got a clue how to go about it.
I have enclosed my dsdt
If anyone can help I would be most grateful.
Mike

hello

if u use hdaenabler.. no need dsdt for sound... the enabler is to avoid dsdt edits

anyway the sound in mac os x , always need a proper patched kext.. mac machine don't use alc..

the kext u use is not the right one for u specs..

the edits in dsdt for sound is to help identify in applehda the layout id of the kext

like (0C) layout 12 in use in the kext

good hack

Thanks for your reply,
does that mean no amount of dsdt hacking will get sound to work without kexts and that my only option is to find another kext?
Thanks again for fixing my dsdt for sleep, that was much appreciated.

I never got ALC 262 working , so I bought a USB Audio > netgear $10.98 works great with my bose 123 sound system.

found a ALC 262 kext with dsdt txt but didn't know how to edit either.

but it's a HP 7700 desktop

Can you be more precise about the model of ALC269, example mine is ALC269VC2 HD. If your is that take these kexts and insert this in your DSDT
