zoliky Posted January 9, 2013 Share Posted January 9, 2013 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! codec_dump.txt.zip Quote Link to comment Share on other sites More sharing options...
Mirone Posted January 9, 2013 Share Posted January 9, 2013 Use: "hda-gfx", Buffer (0x0A) { "onboard-1" }, Quote Link to comment Share on other sites More sharing options...
zoliky Posted January 9, 2013 Author Share Posted January 9, 2013 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? Quote Link to comment Share on other sites More sharing options...
