AppleHDA DSDT

Recommended Posts

Hi,

I need to use this dsdt code to enable my patched AppleHDA.

 

Device (HDEF)
{
   Name (_ADR, 0x001B0000)
   Method (_DSM, 4, NotSerialized)
   {
       Store (Package (0x04)
           {
               "layout-id", 
               Buffer (0x04)
               {
                   0x0C, 0x00, 0x00, 0x00
               }, 

               "PinConfigurations", 
               Buffer (Zero) {}

           }, Local0)
       DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
       Return (Local0)
   }
}

 

Some DSDT I have seen use this additional code in the Store (Package (0x04):

 

"hda-gfx",
Buffer (0x0A)
{
"onboard-1"
},

or

 

"hda-gfx",
Buffer (0x0A)
{
"onboard-2"
},

 

I'm not sure which one should I use for my built-in sound card onboard-1 or onboard-2? Is there a way to figure that out?


I have a HP4540s laptop. If it helps, I attached my codec_dump generated in Ubuntu.


Thank you!

Sorry for being curious, but it has a logic behind it? Did you check my codec_dump?


I read that "hda-gfx" adds HDMI audio support. I have a HDMI port on my laptop. I think I need to add that "hda-gfx" code into Device (GFX0) as well. Intel HD 3000 Graphics.


How can I test the HDMI audio? I have a TV with HDMi support. Should I connect my laptop to the TV via HDMI cable?

yes.

you can test through your Tv

if not work outraas changes should be made in your DSDT.

I return with the results.
