Acer aspire 5750G with Mountain Lion (Unibeast)

Update:

I have re-installed and now have sound working(using Voodoohda-2.7.3.pkg installer) Everything is working and running surperbly. Thanks for all the help. Any more tips or advice would be awesome... Thanks you all...

Voodoo should work, but I think you can only get sound out of the Internal speakers, for full sound functionality you need to patch AppleHDA to enable headphones, microphone, and HDMI audio.

Sound is a lil' buggy with voodoohda. Getting feedback from mircophone. Headphones jack works. But, can still hear my wife taking with headphones in...lol. I've had a few KP's with this kext.. Would like to try applehda(patched)... In linux(not installed anymore). Audio was listed as a ACL271x and seemed to work well.
In terminal "lspci --nn in linux produced.

I have recently installed ML 10.8.2 on my 5750G using patched bios and DSDT.aml form Sahand_N in post #9 everything went well including wifi (AR9285) however like many others my HDMI audio did not work. Now i am using the DSDT.aml from Merv77 in post #88 and now i have HDMI audio but no wifi.
I want to keep the DSDT.aml from Merv77 what do i need to edit to get my wifi to work?
Thanks Montyboy

How did you enable WiFi before Merv77's DSDT?

When i used the dsdt from Sahand-N in post #9 it just worked without having to do anything. I have tried all day to edit the dsdt from Merv77 without luck, i have never edited a dsdt file before. Any help and advise would be great. Thanks Montyboy

Okay, try the kext I have attached - install, repair permissions and reboot.

If not then check in the DSDT for this code:

Device (ARPT)
{
	Name (_ADR, Zero)
	Method (_DSM, 4, NotSerialized)
	{
		Store (Package (0x0C)
			{
				"AAPL,slot-name", 
				Buffer (0x08)
				{
					"AirPort"
				}, 
				"device-id", 
				Unicode ("*"), 
				"device_type", 
				Buffer (0x08)
				{
					"AirPort"
				}, 
				"model", 
				Buffer (0x34)
				{
					"Atheros 9285 8802.11 b/g/n Wireless Network Adapter"
				}, 
				"subsystem-id", 
				Buffer (0x04)
				{
					0x8F, 0x00, 0x00, 0x00
				}, 
				"subsystem-vendor-id", 
				Buffer (0x04)
				{
					0x6B, 0x10, 0x00, 0x00
				}
			}, Local0)
		DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
		Return (Local0)
	}
}

Thanks for your reply but again i have tried many times to edit the DSDT but i can never save it as "aml" .
When i open the dsdt.aml from Merv77 with dsdt editor and click on compile before i have made any changes i always get 1 error, when i click on fix errors it has no effect.
Could it be because i am using the patched bios?
The error is: 17 Error Name already exists in scope (/TNOT)
Any more help help would be great. Thanks montyboy

 

[T1hom7as]

It's a common error, just go to the line which I think is line 17 and delete the whole line with the /TNOT entry. It should now compile and you can then save.

Are you using Atheros WiFi adapter too?

Regards,

 

[Montyboy]

thanks again for the reply i will give it another go..
Yes i am using the Atheros wifi adapter. i will let you know how i get on...............montyboy
