Set Ubuntu sound volume on boot

Ubuntu startup / login sound can be very loud, but I like to have it. I wrote a script that uses amixer to set the volume to 25%. This is the level that I like, but when I use TV-out or headphones, I need to increase the volume. It seems I can not run the script until the input sound starts. I tried cron @reboot and put a symlink to the script in / etc / rc3.d / and in my .bash_profile script. Only the third method actually sets the volume correctly, but after playing the input sound.

Ideally, I want to run a script when I am logged out at night, or just before the ubuntu login screen is displayed.

Here is the volume setting:

`/usr/bin/amixer -c 0 sset Master,0 25% > /dev/null`

Recommendations for other methods are evaluated.

You might want to add this line to your type. /etc/rc.localThis may not be fast enough, since rc.local will be called after gdm.

Also note that the default runlevel is on Ubuntu 2 , not 3 . Your link in rc3.d probably did not work simply because you are not using runlevel 3. The runlevel is configured by default with / etc / event.d / rc-default

Yeah, yes, but do they also contain an "alsactl repository" at shutdown?
