It wants us to change the DSDT in order for the patches to work. Is that required with the DSDT from post 1?

Depends on the layout-id used by the AppleHDA you've created. It is an arbitrary choice. Mine uses layout-id 86. See patches/audio.txt.
So there is a prepatched version of AppleHDA for the ALC283 made by Mirone
However, if I delete the previous HDA and _ALC283, and place the patched one in, there is no sound
Is there a way to use the prepatched version without changing DSDT, or is that the only option.
The prepatched install instructions say "Use Layout 3 in the Patch HDEF your DSDT." not sure what that means exactly
The following code is included
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x0c)
{
"built-in",
Buffer (One)
{
0x00
},
"layout-id",
Buffer (0x04)
{
0x03, 0x00, 0x00, 0x00
},
"PinConfigurations",
Buffer (0x00)
{
0x00
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
Update: For those who want better audio (fixes heavy bass and low treble):Ignore any other DSDT patch instructions. Modify patches/audio.txt for layout-id 3.
Rehabman, with the HDA patch, HDMI audio is not working. Is there another file I need to edit?
The audio will come in 1-2 second snippets but shifted in pitch, then silence
cd ~/Projects/y50.git
git fetch
git checkout alternate_audio
make install_hda
make clean
make patch
make
make install
You probably forgot to change the layout-id in patches/hdmi_audio.txt.

I have taken the content from Mirone's AppleHDA that you linked in post #941.
It is available in the 'alternate_audio' branch.
To test it:
Code:cd ~/Projects/y50.git git fetch git checkout alternate_audio make install_hda make clean make patch make make install
^ Script doesn't work. No sound!
I've rebuilt cache already, so not sure what's wrong
Did you restore AppleHDA.kext to vanilla?
Did you rebuild cache per post #1, "Known Problems" "Audio"?
