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

Hi there,

I bought a Acer Emachines E732ZG Laptop, and now I've running 10.7.1 & 10.7.2 on it.
Everything works fine, except for the sound:

Every VoodooHDA kext I use causes a loopback from the internal speakers to the mic, or the devices simply aren't listed in Systempreferences. I also tried some AppleHDA.kext, which did not work neither.

After opening my Lapt I found out that theres a ALC272x codec on the mobo, but theres also a HDMI device from the Radeon 5470.

I downloaded SystemInfo, and added the IDs to several voodoo kexts, with no success.

The Interesting thing is that every time I want to access sound preferences the system preferences hangs up and I have to force quit. Same on youtube with Safari or songs in iTunes/ VLC or MIDI Setups.



Has anyone an idea how to fix that org what I could try else?

No one any ideas? =(

Well, you won't believe it, but after i tried the solutions in your link I deleted voodoohda.kext so there was no sound driver on the system. Then I booted up and started iTunes and noticed that if I play a song, iTunes shows the song, but makes no signs of playing it. The time of the song remains on 0 and the 'progress bar' (you know, the bar on the top of iTunes) doesn't move either.
Same symptoms on youtube, etc..

well, in my opinion this seems like voodoohda isn't the problem, but something else. wtf ist the problem with my lion?

I believe that you have to do a clean install...

means that I should not install via iAtkos, but from the .dmg from Appstore?

Yes... It`s better...

Well, I've done a clean install, but it didn't solve the problem.

I've played arround with several voodoohdas and noticed, that everytime I add the HDMI to KitProperties the devices are shown well in System Preferences, but in PrefPane only the HDMI device is listed. What does that mean?

Here's my info.plist (2.7.3) just to make sure I added the devices right:

Code:

			<key>VoodooHDAVerboseLevel</key>
			<integer>0</integer>
		</dict>
	</dict>

And here is my getdump: Shouldn't the ALC272x appear in the getdump too? How do I add the Nodepatch to info.plist, is there a guide or something like that somewhere?

Code:
