Yes, if you do --disable-audio-alsa and/or --disable-audio-oss on 
GNU/Linux systems, it will break a lot of MythTV functionality, even if 
it's only a backend.  It's used by the backend itself.  You need the 
library functionality, even without hardware--just like you need the X 
libraries to install Qt, which you need to install mythbackend, even if 
you never start (or install) an X server.
