Ok, I had a fully working 10.5.8 on my 10v installed via mechdrews USB method guide.
Today I tried the SL install using the guide and NBM found in the thread here. Restored the DVD image to the USB drive, ran NBM on it, installed without any errors. After install I booted into safe mode with -x and ran NBI with the suggested settings. Restarted and got to the main desktop with no problems.
Now, everything else works, Wifi, sleep, etc. But my sound show an X over the volume control when I try to adjust and the icon on my menu bar is grayed out.
Not sure what went wrong since the guide says that audio should be working on the 10v.
Any suggestions or workarounds? I saw a few for the 9, but none for the 10v.
