please help!! my acer aspire 4738 has successfully install maverick 10.9 in it
i already got every single thing working in it
except the audio part.
i thought the ethernet and wifi parts is the hardest but i got them running already.

i used voodoohda.kext to run the audio and it is working
the audio device detect my speaker atapi but not my speaker HDMI 

so the booting sound and the shutdown sound doesn't work
but the normal sound like iTunes or video file is working.
BUT after like a 30 minutes, the audio will suddenly glitching and stop.
and then if u play the song again the audio would be as buggy as hell and i must re-set the audio frequency again in MIDI to restore it every-time.

is there a fix for this.
my laptop is acer aspire 4738 with sound card realtek alc272

 

if u need more specified information just tell me

 

sorry for bad english

hey first thanks for the reply ^^
and i try to download the kext from the link you given and there is a read me
"This is the version of Applehda.Kext Mavericks hope it works for everyone!

Note: You must change the Layout to 1 in the DSDT patch HDEF."
what does it mean to change the layout to 1?
the dsdt that he give me :

Method (_DSM, 4, NotSerialized)

                {

                    Store (Package (0x0c)

                    {                        

                        "built-in",

                        Buffer (One)

                        {

                            0x00

                        },

                        "layout-id",

                        Buffer (0x04)

                        {

                            0x01, 0x00, 0x00, 0x00

                        },

                       "PinConfigurations",

                       Buffer (0x00)

                       {

                           0x00

                       }

                    }, Local0)

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

                    Return (Local0)

                }
