Hi, /etc/rc.d/rc.local does not need to exist. On My DM355 the start script /etc/init.d/rcS checks for this file and if present + executable it gets invoked. This file is meant to hold 'local' configuration items as required by a particular machine. The idea here is to prevent modification to otherwise common files. So, if you make sure that your initialisation is checking for the rc.local, you should be able to create the file & make it executable for yourself. Something like... #!/bin/sh #
# Add local configuration here echo "Set mixer" /usr/bin/aumix -m R -m 100 -v 80 ..should do (don't forget the chmod a+x on the file after you create it).

I guess mixer settings should be done on target side .
