Today I installed El Capitan (10.11.6) and things seem to be working very nicely...except for there's no audio. I've spent a lot of the day looking at all the fixes/patches/injects that would supposedly get Realtek ALC888 audio working on this older system, but so far to no avail. However, I'm curious about one thing...
This system has had Mountain Lion on it (dual boot) and running fine for years, and has sound...at least through the headphone jack...using a VoodooHDA kext. When I check IORegistryExplorer (searching for HDEF@1B) to see what the 'layout-id' is it shows <01 00 00 00>. So from what I've read that suggests ML and VoodooHDA are seeing the audio hardware with ID 1, etc etc. I've read that sometimes other ID's may work, but in this case it is showing as 1 and I do have some sound on the ML installation.
But there is no audio under El Capitan, and when I checked the EC installation using IORegistryExplorer---it shows the layout ID as <00 00 00 00>, huh?...not <01 00 0 00> like ML. In some posts I've seen the all-0's indicates 'invalid'. I suppose that's why it doesn't want to work in EC, but then why is it working in ML and showing <01 00...etc.
Anyone have any ideas on how to fix the EC installation?
Thanks..
