I modified the script as follows: #!/bin/sh exec >> /home/jens/log.file echo "=================== /usr/bin/amixer -c1 ======================" /usr/bin/amixer -c1 echo "Return value: "$? echo "==============================================================" echo echo "============== /usr/bin/amixer -c1 sset Mic 75% ==============" /usr/bin/amixer -c1 sset Mic 75% echo "Return value: "$? echo "==============================================================" echo echo "============== /usr/bin/amixer -c1 sset Mic 75% ==============" /usr/bin/amixer -c1 sset Speaker 25% echo "Return value: "$? echo "==============================================================" echo The output of *each* "amixer" call is always: Usage: amixer <options> [command] Available options: -h,--help this help -c,--card N select the card -D,--device N select the device, default 'default' -d,--debug debug mode -n,--nocheck do not perform range checking -v,--version print version of this program -q,--quiet be quiet -i,--inactive show also inactive controls -a,--abstract L select abstraction level (none or basic) -s,--stdin Read and execute commands from stdin sequentially Available commands: scontrols show all mixer simple controls scontents show contents of all mixer simple controls (default command) sset sID P set contents for one mixer simple control sget sID get contents for one mixer simple control controls show all controls for given card contents show contents of all controls for given card cset cID P set control contents for one control cget cID get control contents for one control And the return value is always 1. It is as if amixer ignores all parameters and then prints out the same as if it has been called with "--help" Best regards, Jens ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
