Need lion kext and dsdt patched for Acer Aspire AM7720

[oldnapalm]

Yes, that's the one I'm using

Try replacing the key IOPCIClassMatch by IOPCIPrimaryMatch and set your ID in its value.

Before

IOPCI[color=#FF0000]Class[/color]Match
0x04030000&0xffff0000

After

IOPCI[color=#FF0000]Primary[/color]Match
0x[color=#FF0000]3b56[/color][color=#008000]8086[/color]

0xDeviceIDVendorID

To find your device/vendor ID

New day - new hope ! I worked as you told me to do yesterday, and .....

You are the best !

I got the kext from your link to be quite sure I do not mess anything and changed OPCIPrimaryMatch and values.

for me it is :

IOPCIPrimaryMatch

0x3a3e8086

And worked !!!!

So now, in Output Tab I have :

Line-out (Green rear) -- that one I use for sound output, and

Digital-out (Black HDMI) -- never used, not sure if it works ...

The front Headphones output functions too.

Now, do you think that my X-Fi Titanium Family Soundblaster card will do it ? And is it possible to have two cards in VoodooHDA ? Two strings into the same IOPCIPrimaryMatch, or another Key ? Or not possible at all.

In any way, now I'm happy

Thank you very much !

I think it doesn't work with 2 cards, that's why we specify the card ID in IOPCIPrimaryMatch instead of a range in IOPCIClassMatch (not sure, you can test).

I will try. Basically the question is if it will work with the other card, if I put his numbers, even w/o the m/b one (I think I have to disable it first from BIOS, right?).

Because of the fact I don't use AppleHDA, do you think I need the patched DSDT, or I'll get sound with VoodooHDA w/o DSDT (I don't know what exactly did change in it ...)

remove kexts

add in boot.plist

<key>GeneratePStates</key>
<string>Yes</string>
<key>GenerateCStates</key>
<string>Yes</string>

Thanks Mald0n for your help, with your help and the support of oldnapalm, we did it !

Thank you !

If the offboard card works with VoodooHDA, you don't need to disable the onboard one, just replace 0x3a3e8086 by device/vendor ID of the other card.

You can keep using the DSDT patched by Maldon, you don't need the HDEF patch I applied.

See trick 4 on official topic about 2 sound cards

http://www.projectosx.com/forum/index.php?showtopic=355

4. If you have two sound cards, for example other one is HDMI output on Video card then made info.plist
