I installed qCommand to execute a script as root (real bash is installed).
#!/bin/sh PIDtoKill=`ps axuw|grep adsprpcd|grep audiopd|grep -v grep|grep -v restart|awk '{print $1}'|grep '[0-9]'|grep '^[0-9]*$'` if [ "x$PIDtoKill" != "x" ] then #echo "PIDtoKill: $PIDtoKill" #kill -9 $PIDtoKill 2> /dev/null 1> /dev/null kill -15 $PIDtoKill fi
So, a normal user can just tap a few times on the screen and have call audio again.
This is faster than rebooting.
