Thread: ALC272X & VoodooHDA: System hangs up while trying to make sound

Yeah, thanks for your help, but I still have no sound..
Could you please take a look at my info.plit here, to make sure I did nothing wrong there? 'Klick'
I also tried replacing 'IOPCIPrimaryMatch' with 'IOPCIMatch' & the Subvendor, but I only got a kernel panic.

You said I should write this in AppleHDA, I think you meant VoodooHDA, since theres no NodesToPatch in AppleHDA?

I there any problem with that HDMI codec? =(

This is weird...

Everything seems to be OK with your changes... But.. Taking a look at the "info.plist" of the VoodooHDA 2.7.2 there`s a few differences from the thread that i showed to you... Honestly, I don`t know if this may affect the final results, but these are the only "differences" that I found...

First > the example that I made for you was using the sample from the thread, so, this information...

Code:

               <dict>
                                <key>Codec</key>
                                <integer>0</integer>
                                <key>Node</key>
                                <integer>23</integer>
                                <key>Config</key>
                                <string>0x99130110</string>
                                <!-- Speaker -->
                        </dict>

Is written by this way on the 2.7.2 version (as I told, I don`t believe that changing only the sequence may affect something, but as I'm not a developer)...

Code:

               <dict>
                                <key>Codec</key>
                                <integer>0</integer>
                                <key>Config</key>
                                <string>0x99130110</string>
                                <key>Node</key>
                                <integer>23</integer>
                                <!-- Speaker -->
                        </dict>

About the panic, try changing IOPCIClassMatch from this...

Code:

<key>IOPCIClassMatch</key>
			<string>0x04030000&amp;0xffff0000</string>

To IOPCIMatch...

Code:

<key>IOPCIMatch</key>
			<string>0x04981025&amp;0xffff0000</string>

I saw the DUMP only for your ALC272 on the link that you pasted here...

I did`t see the DUMP of any other device....

Well, thats because I only wrote the ID of the ALC272 codec into the info.plist, cause when i add them both (alc272 & hdmi) only the hdmi device appears in the dump. is that maybe the problem?

Thanks for your advices, I'll try them later, cause I'm in ubuntu atm.

I belive no, but, who knows...

You can try by adding a entry for your HDMI device on the info.plist by following the Slice`s tip of add a second entry to the "IOKitPersonalities" of the kext > Voodoohda Driver - Project OS X Forums

Well, I added the HDMI to the KitProperties but it still doesn't work.. HDMI is not shown in system preferences, and theres still no sound, and in iTunes/ youtube the 'time bar' doesn't move..

i'm so sad about that *$§)"%()

€: Here's my Info.plist, is there s.th. wrong?

'Klick'

€2: Is it normal that the HDMI device doesn't appear in get dump?

€3: Well, okay, in VoodooHDA.prefpane only the HDMI device appears.. That's weird..

Check if you can see other device on "Application > Utilities > Audio MIDI Setup"...

There are the same like in system preferences...
Do you think i should try it with AppleHDA? But I've no idea how to patch a dsdt

I believe that`s a good idea...

To patch your DSDT, first take a look here and use DSDT Editor and Patcher to made one for you > olarila.com • View topic - DSDT patching 101

With AppleHDA it's not working too...
Does anyone have an idea what the problem could be? Is it maybe that I don't have special kext/dsdt for my graphics, but GraphicsEnabler?

Certainly no...

BTW, did you already tried this??? > AppleHDA for ALC272 (10.7.1) - Downloads - OSx86.net
