The integration of PSARC 2009/626 replaces the mixerctl application with a more user-friendly "audioctl" application. To get a brief synopsis of the audioctl syntax, use "audioctl help". A full manual page is included in the mail log for PSARC 2009/626, in the event you need more detail before the man page proper becomes available. Users using BFU should probably remove /usr/sbin/mixerctl from their proto area to avoid complaints emitted during archive creation.
