X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 10 Mar 2004 18:28:31 -0000 The default volume levels on my laptop (75:75) are rather loud when using headphones, and I found myself constantly having to pop up a terminal window to run mixer before listening to mp3's, etc. So, during a fit of boredom, I wrote a simple mixer rc.d script that adjusts mixer values based on an optional /etc/mixer.conf. It only works with /dev/mixer though and doesn't support multiple sound cards, mostly because I couldn't think of a sane but simple syntax for mixer.conf. The script and a sample mixer.conf are below. I'm not sure where to send this for review (moving the rc list to @FreeBSD.org would be helpful perhaps) so I'm splatting it here. ---- mixer #!/bin/sh - # # Copyright (c) 2004 The FreeBSD Project # All rights reserved. # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.
