I'm trying to get sound working on a new laptop at the moment and have just installed the VoodooHDA kext.
This is causing a KP and horrendous sound at boot up.
I'm now unable to boot even using -x or booting ML from the installer.
I'm trying to delete it from the command prompt of the installer like this

rm /Volumes/MLion/System/Library/Extensions/VoodooHDA.kext

It's telling me that is a directory
can anyone tell me how to do this.

Care to share after removing the voodooHDA why your system still didn't boot?

[Crabhunter]

I havent got a clue, system was booting until I installed VoodooHDA then wouldn't boot with it, deleted it but it still wouldn't boot but at least it didn't make a screaming noise like it did with the kext.
re-installing as we speak but this time to a small partition that I'm going to restore to the the large partition so if (when) I screw it up again it won't take so long to get back again.

You have to boot with -f or UseKernelCache=n after deleting a kernel extension from single user mode, otherwise it will load from the cache anyway on next reboot.

very easy, boot with -s

mount /
cd System/Library/Caches
rm -rf *
diskutil repairPermissions /
sudo kextcache -system-prelinked-kernel
reboot -R lnk

From terminal you should use:

rm -rf /System/Library/Extensions/VoodooHDA.kext

The command you have provided will give back an error, stating it is a directory, so you need to use the -r or -rf flag, and only work if OS X is installed on disk0s3.
