Alsa Mixer Problem

Fogey37 · 02-20-2015, 02:53 PM

I am interested in finding out how to save the sound settings for the Gnome Alsa Mixer, in Ubuntu 14.04 , Trusty Tahr. Each time I UNMUTE the speaker bar, it resets to mute with the next boot up.

Code:

$ sudo alsactl store

should work

Tried all the very elegant suggestions to save the Alsa Mixer Settings, But alas, The mixer
resets every time I reboot. Speaker bar and Mike Bar always revert to "MUTE" and the slider for these
two items turns all red.

this Fogey is perplexed.

Once you have set up alsamixer, use the above, then next time you boot up they should be as you left them.

There is a command line interface to alsamixer. It is called amixer. You could write a simple bash script and auto run it whenever you start Gnome.

amixer is not terribly complicated, you just have to find out which card you are talking to and which are the relevant controls. It is best to try the commands interactively so you are sure which commands are the correct ones before putting them in a script.

Set your mixer levels.

Then use 'alsactl store' to store and 'alsactl restore' to restore.

Use the -f option to store state in custom file and then to restore from it.

Usually distros (init scripts) store it to the default file and restore from it after reboot.
