sound card troubles alc888b

[boumbo]

Hi,

i just make a retail installation of SL on my computer , all is fine but i have one big trouble.

The sound doesn't work.

My MB is an gigabyte GA-H55-UD3H , on the website it is notice that the audio chipset is a ALC889 but when i looked my dsdt file, it is an ALC888b and in the bios , it is notice as using Azaliacodec

I found a legacyHDA.kext or a legacyHDA888b.kext, or voodoohda.kext but it doesn't work.

How can i do to make the sound working (i have install chameleon RC4 with an extra directory).

Should i modify the kexts before put them in the extra directory?

How must i use the legacyHDA888b kext?

how must i use the voodoohda kext?

is it possible to have the 7.1 channel working?

 

thank you so much and have a great day

I have the same question. ALC888b ?

 

I have i3-530 on a GA-H55M-UD2H with 4GB memory, GeF 9600GT, SATA HDD and SATA Optical. SL 10.6.3 via tonymacx86 [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] / MultBeast method. Have systematically tried everything to get the sound to work. I am running a USB sound solution at the moment.

 

If anyone has this chip running, please provide the install guide and kexts used.

 

Thanks,

neil

I share the same motherboard as you H55M-UD2H and it uses the ALC889 onboard sound driver. I found on tonymac's blog, he has built a wonderful installer that is only a temporary solution for non-vanilla kernels. Anyhow, it only allows internal speakers, which is no fun! Let me know if any of you find any solutions!

You will need Legacy888bHDA in /Extra, and you will also need AppleHDA "rolled-back" to 10.6.2 in /System/Library/Extensions.

 

Additionally, and finally, you will need to remove most of the HDEF device, leaving it with just:

 

 

Device (HDEF)

{

Name (_ADR, 0x001B0000)

Method (_PRW, 0, NotSerialized)

{

Return (Package (0x02)

{

0x0D,

0x05

})

}

 

Method (_DSM, 4, NotSerialized)

{

Store (Package (0x04)

{

"layout-id",

Buffer (0x04)

{

0x77, 0x03, 0x00, 0x00

},

 

"PinConfigurations",

Buffer (Zero) {}

}, Local0)

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

Return (Local0)

}

}

 

The "roll-back" of AppleHDA to the 10.6.2 level is essential to get ALC888/ALC888b sound to work at 10.6.3, 10.6.4, and beyond, because Apple, in all its wisdom, "broke" ALC888/ALC888b (but not ALC889/ALC889a).

 

Alas, the lack of an ALC888/ALC888b solution has forced some users to consider an ALC889a-based mobo, when an ALC888b-based mobo would otherwise suffice.

 

An ALC889/ALC889a solution is also available, but the Legacy889a link is presently broken.
