Like I said, the kernel module file "snd-hda-intel.ko" is missing from my latest /lib/modules/. I believe that's the file that would set up my audio card. But how to generate it? I'm assuming it was there before I removed my pre-compiled alsa-utils,etc, to make way for my local build (?). But then my local build failed to generate the new version of this file (?) > -- > Chris Hermansen · clhermansen "at" gmail "dot" com > > C'est ma façon de parler.
