  • PC Speaker support in FreeBSD

    To enable PC speaker support, add line to the /boot/loader.conf: 
    speaker_load="YES"
    This will load speaker device daemon at the boot time. To start it manually: 
    kldload speaker
    To make a simple sound: 
    echo -ne '\a'
    To make some sound on PC speaker using musical notes: 
    echo "l32<<<<F" > /dev/speaker
    (see man speaker for more sound options).
    To make a sound every time someone accesses your webpage, create a following script and run it in the background: 
    #!/bin/sh
while date
 do
  tail -F -n 1 /var/log/httpd-access.cabin.log | echo "l32<<<<F" > /dev/speaker
 done
