Analog devices SoundMax AD1981HD on HP notebooks, not supported? is the output port configuration different than IBM? Options

[forcer]

I tried to search barely everywhere, but I'm not able to get sound from my soundcard.

Does anyone have experience with working soundmax AD 1981 HD card on HP notebook?
If someone knows how to help, it would be greatly apreciated, as there are lots of users with same problem.


All HW specs can be found in signature.

Although my one is IBM Thinkpad X60, there is AD1981HD on it. Hope my way can help

1. Open /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/Info.plist
2. Find "<key>IOHDAudioCodecVendorID</key>"
3. In the next line where IOHDAudioCodecVendorID was found , replace "0x????????" with "0x11d41981"(You may check if your AD1981HD use this devid at Device Manager in Windows)

Finally,in terminal:
sudo -s
cd /System/Library/Extensions
chown -R root:wheel AppleAzaliaAudio.kext
find AppleAzaliaAudio.kext -type d -exec /bin/chmod 0755 {} \;
find AppleAzaliaAudio.kext -type f -exec /bin/chmod 0644 {} \;
cd /System/Library
rm -rf Extensions.mkext Extensions.kextcache

could you please post your kext file as this doesn't work for me on hpnx7400 with 1981HD.
did modify other kexts, did you remove some?

On IBMs, there is no problem with this soundcard, problem is, we on HPs can see output in Sys Prefs->sound, but the sound is not comming from anywhere.. mic/headphones/internal speakers..
I think port configuration is different. I have also noticed that mute button is always on on my keyboard...

yes you're right, i also have the mute button always on under mac os X

maybe someone clever could help us?

[sheriffbounce]

hey fellas,

same issue here on HP NX9420... used the appleazaliaaudio.kext changed everything...
got the volumeslider in the menu... can see HD Output in Adio/Midi-configuration but get no sound...
by the way Input is not available...

BUT i remember a thread a while about the port configurations - maybe we have to go this direction (it was something with using Linux)
but i'll search for it and come back with some more infos later...

cheers
sheriff

[NHJ]

when i go to about this mac, the page to see the hardware, the built-in audio is missing while i have the volume slider and hd ouput available.

when i do a ioreg -l i see my 27d88086(hd bus) but not my 11d41981(soundcard)

can someone on ibm or another laptop confirm or infirm that it's the same for him please?

do you have microsoft UAA driver installed? could you please look in windows system infos for the vendor and dev ID of your UAA Bus? this is the HD Bus...
maybe this one must be added there...

hello yes 27d88086 is the UAA device

[sheriffbounce]

hello yes 27d88086 is the UAA device

hmmm just reading a little bit about this UAA driver...
very interesting stuff about pinconfiguration there...maybe this helps us....but I'm not sure...
let's see... I'll keep u updated...

[sheriffbounce]

okay guys tried some things and currently trying to use ALCinject together with AppleHDA since we have a HD device
does anybody of you have more detailed knowledge about Pathmapping in AppleHDA.kext?????

here is my linux log, maybe anyone of you knows hows to put it into the info.plist... i'm a little bit stuck because of the AUDIO MIXER and the AUDIO SELECTORS (i assume it's the same) since the mic in for instance connects to an audio selector instead of a mixer... i deleted all dependencies for the additional ports availbale via dockingstation... don't have one yet... also took out the modem audio stuff...

Is there a mute LED, and is it on? My theory is that the mute LED needs to be "initialized"/switched off, but that's only a theory.

Maybe someone more skilled than me could have a look at how Linux does it:
http://archives.free.net.ph/message/200603...a78cb4c.en.html
http://lxr.free-electrons.com/source/sound.../patch_analog.c
http://people.redhat.com/linville/kernels/...hp-nx6320.patch

yes there's indeed a mute led wich is always on.

i think the led disappears when the right configuration is loaded for the codec.

[solu]

i think the led disappears when the right configuration is loaded for the codec.

Then the only ;-) question is how to load the correct configuration...

[NHJ]

Then the only ;-) question is how to load the correct configuration...

i have big hopes that HDA patcher will support our soundcard, it uses the codec dump from linux to patch the .kext to get sound output, line in etc.

taruga is adding support for some ADI maybe ours will be included.

btw do youhave your core2duo running on both cores? on mine i have to disable it in bios.

I'm giving big hope in AppleHDA sound driver from taruga.
If you want to use only one core in OSX you can use switch cpus=1 in boot loader(no need to disable dualcore support in bios) or also you can edit com.apple.boot.plist and add this flag there.
My notebook with latest kernel from semthex is very unstable with both cores enabled, so It's global issue.

thanks i did that, but i don't think it's related to semthex kernels, on my laptop i have never been able to use both cores even with the 10.4.6 not even while installing.

in another post, semthex stated it was due to a bad acpi implementation...
