Optimized AppleHDA for Realtek ALC 888 on Lion - Update

[mrhevor]

I have a Compaq DX 2300 with ALC888 ICH7 Azalia working perfect on Mountain Lion 10.8.1.
I use this AppleHDA from Lion 10.7.3 compiled for ALC888 (renamed now ALC1200) + DSDT compiled with Azalia definitions.
My ALC888 (motherboard built-in) details are:
ID device : 8086 - 27D8
ID subsystem : 1462 - 7336
Intel 82801GB ICH7

I hope help who try to have audio with AppleHDA.
Best regards.

Thanks a lot. Could you please post your IOREG and HDEF section from your DSDT? It's important to know your layout-id to correct my DSDT.

Hi mrhevor,

I have the same ID device : 8086 - 27D8 as you (00:1b.0 Audio device [0403]: Intel Corporation N10/ICH 7 Family High Definition Audio Controller [8086:27d8] (rev 01) )

Im not sure on the sub id tho. But I don't know what you have added to your DSDT.

Could you please upload your DSDT or maybe what edit you did?

My M/B is a Asus P5KPL-AM running ML 10.8.1

Thanks,

Ross

Hi, Toleda. That's me again ) I guess I've found the problem with my ALC888. Some audio codecs (just as mine) have a node 11 aka "Input Monitoring Level (OSS: igain)". It's some kind of an additional volume control, which controls all Inputs and Outputs together. I don't know what's for it is intended and how it should work, but when I disable this node 11 via config in VoodooHDA, I get fully working sound sound with all inputs/outputs, just as in Windows.

Input Monitoring Level (OSS: igain)
|
+- control 2 (nid 11 in 2): dir - in oss: igain -34/+12dB (32 steps) + mute
+- control 4 (nid 11 in 5): dir - in oss: speaker, igain -34/+12dB (32 steps) + mute
+- control 9 (nid 12 out): dir - out oss: vol, pcm, igain -46/+0dB (32 steps)
+- control 12 (nid 13 out): dir - out oss: vol, pcm, igain -46/+0dB (32 steps)
+- control 15 (nid 14 out): dir - out oss: vol, pcm, igain -46/+0dB (32 steps)
+- control 18 (nid 15 out): dir - out oss: vol, pcm, igain -46/+0dB (32 steps)

If AppleHDA allows to disable some nodes, it would be nice to test such a variant. I think that's the problem, actually.

Very interesting. Actually, Node 11 is disabled with this pinconfig: 21171cf0 21171d00 21171e00 21171f40 in all versions of the Optimized Realtek AppleHDAs. Node 11 (SPDIF Out at Int ATAPI) is usually the the 2 wire SPDIF motherboard to graphics card audio out interface for HDMI audio on older graphics cards without a HDMI audio codec.

Try two experiments with the Optimized 888 AppleHDA;
1. Replace the above pinconfig with 21171ca0 21171d01 21171e43 21171f99. This enables Node 11 in OS X.
2. Remove the above pinconfig. May cause a sound assertion and/or add a device in System Information/Audio.

i'll use your DSDT edits, since mine doesn't work anymore (i know about the stuff of the update 10.8.2 and audio DSDT edits)

i have the same mainboard (Dell X501H), and i have checked with windows and with linux, and yes, the mainboard audio chip is v100101; it seems to be ALC1200/ALC888 , BUT when you check the audio panel you got a message telling that is a ALC888S, i'm attaching screenshots of the info.

so then, Toleda, you have found something useful about that?? i think is something about audio jack sensing

888s is a marketing name, same as 888.

Yes, it is one of two Sticky threads in the Audio Forum.
