i found out more about this "bug": pressing the mute button writes 0 to /proc/acpi/ibm/volume. so in order to get the desired behavior it would be necessary to read out the volume level from /proc/acpi/ibm/volume before setting it to 0. save it somewhere and then if the users push the mute button again write the saved value back.
