The best bet for your sound problem is to use [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] and select the following options..
System Utilities
-Rebuild Caches (Select)
-Repair Permissions (Select)
Drivers & Bootloaders
-Kext & Enablers
--Audio
---Realtek ALCxx
----ALC8xxHDA (Select)
----AppleHDA Rollback (Select)
----Non-DSDT HDAEnabler
-----ALC892 (Select)
Once complete reboot and you should have basic stereo sound.
Then go to http://www.tonymacx8...hp?f=79&t=14725 and install the beta kexts to enable full support for all speakers (select the first of the three speaker options when you run the installer).
The audio problem is just a bug in the installer script, usually running it again from the desktop will fix it. It does appear to install everything correctly but for some weird reason it sometimes doesn't set the permissions properly or load the kexts. If running the installer again doesn't fix it then just run kext utlity in full service mode (i.e. just double click it) that usually does the job.
Hello Andy,
Thank you so much for the thorough reply. So once again, please forgive me for being such a noob.

I'm still getting a grasp of all this kext an enabler installation.
So I did a fresh install and did the following steps:
1) I used TonyMac's [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] to run the installer DVD
2) Updated to 10.6.6
3) Ran Bridgehelper
4) Ran [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] with the exact suggestions you told me to check off. I didn't even check off [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] or OSX86 software (not sure if I was supposed to)
5) Rebooted
At this point I just ran into the same problem:
I have stereo sound, but extremely distorted and scrambled. I've noticed that some people with the Pro boards have this problem and their workaround is using a sound card, but I really would like to help you find a really perfect method of enabling the on board sound
So....
6) I install the beta kexts from tony mac
7) Rebooted and sound still had the same distortion
8) I decided to copy the package from you boot CD and ran it once again
9) Rebooted
10) The sounds worked perfectly again! But I still ran into resolution display limitation. I'm assuming cause your package is mainly for ATI support?
This time, I'm booting with you CD.
So to be honest, I'm not really sure where to go from here. I'm such a noob, I don't know how to delete the ATI drivers and put Tony mac's NVidia drivers.
I even tried updating to 10.6.7, then lost the sound working properly again, and was only able to boot into the OS with the [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] CD.
Sorry for the craziness Andy. I'm really new at this and more familiar with PC/Windows install. I dont even know where the kext utility is.
All I know is, something with your package makes the sound work perfectly and all I need to do is fix the video after I install your package.
OR
Can you please make a package for helping us NVidia users that incorporates TonyMac's NVidia package, PLEASE! (excuse the caps
Thanks so much for you expertise and generous help on this matter.
