[Genuine MacBook Pro] No Sound from USB SL Installation

[fmillion]

I'm not sure if this is the best place for this but I'm hoping someone can chime in with a bit of knowledge.

 

I wanted to create an external USB installation of Snow Leopard, so I can load disk maintenance and repair utilities onto it that need to run outside the main OS. Since I wanted the USB device to be as universal as possible - I'd want to be able to boot any machine supporting SL - I used my Hackintosh and my official SL 10.6.0 DVD to install it.

 

I used the method in which you execute System/Installation/CDIS/Mac OS X Install.app as root, then direct the installation to the USB drive. (Remember, I'm actually installing to the USB device using my Hackintosh, a Gigabyte build) I then updated the USB device's installation to 10.6.8 on the Hackintosh by simply pointing the update to the USB drive.

 

I then connected the USB drive to my MacBook Pro (2010 model with Core i7). The install boots fine and runs, except that I don't have sound or AirPort connectivity. (Graphics acceleration and Ethernet are fine. Not sure about Bluetooth, haven't checked.)

 

The sound card does show up in system profiler, and its outputs and inputs even are displayed, but the Sound control panel shows no devices. (This is exactly what happened on my Hackintosh prior to installing the ALC888 patch/HDA downgrade.)

 

AirPort shows up in the Networking control panel but clicking "Turn on Airport" does nothing. In SYstem Profiler the Airport section only shows the kext versions and doesn't show any devices at all.

 

The reason I did all this on the Hackintosh rather than on the MBP itself is because the MBP won't boot an OS prior to 10.6.3 and thus won't boot my 10.6.0 DVD, and I was worried if I installed 10.6.3 from the MBP's restore disc it might lock the installation to that specific model so it wouldn't be portable.

 

I'm pretty sure it has something to do with kexts or something. Does anyone have any insight as to how the install process works and how/if I can restore audio and networking from the USB installation and yet keep it compatible with other SL-capable Macs?

 

The USB drive will boot on my Hackintosh too. There, it also has no sound, no Ethernet and no graphics acceleration, but I understand why there and can fix it with appropriate kexts and modifications to config files for Chimera.

 

Thanks for any advice
