Execute:

sudo alsactl store

This should save alsamixer configurations to /etc/asound.state which gets loaded every startup.

You could also save the mixer settings into a custom file with alsactl:

alsactl --file ~/.config/asound.state store

Reloading:

alsactl --file ~/.config/asound.state restore

Seppo Erviälä's answer is right but not complete. As dma_k already noted, man alsactl clearly states at the end that,

/var/lib/alsa/asound.state (or whatever file you specify with the -f
flag) is used to store current settings for
your soundcards.

palacsinit appropriately noted that you can store config into your file with

alsactl --file ~/.config/asound.state store

and reload with

alsactl --file ~/.config/asound.state restore

This can be further improved with placing the second line, the restore command into a .desktop file.

You will need to run nano ~/.config/autostart/alsarestore.desktop, which will open nano text editor and create ~/.config/autostart/alsarestore.desktop file. Entries in ~/.config/autostart/ directory are used to autostart programs and services for specific user on startup/graphical login.

The contents of the .desktop file should be the following:

[Desktop Entry]

Type=Application

Terminal=false

Name=alsarestore

Exec=alsactl --file ~/.config/asound.state restore

Among other things, you could store your config in /etc/asound.state and symlink it to /var/lib/alsa/asound.state, but this one is more of a suggestion rather than tested solution

After 2 months of trying to make "sudo alsactl store" to work, I finally managed to do it.
Firstly type in terminal "alsamixer" to enter the alsamixer UI. Then make the configurations you need(e.g increase speakers/headphones level or unmute something pressing "m" on keyboard).
Now the most important part. Before you exit alsamixer, open a new terminal and do : "sudo su" to get high privileges (Be very careful with commands you use in "sudo su" mode because you may destroy your system) and then do "alsactl store" to save alsa settings. Then close both terminals and restart your computer. This will do the job.

After running sudo alsamixer the mixer should should retain the changes you make.

See Sound does not work once my profile loads on which answers you can find a clue also.

Good luck!

Alsa-Json-Gateway https://github.com/fulup-bzh/AlsaJsonGateway supports store/restore of sound card sessions from JSON/REST API

• list sessions /jsonapi?request=session-list&cardid=hw:0


• store session /jsonapi?request=session-store&cardid=hw:0&args=MySoundConfig


• restore /jsonapi?request=session-load&cardid=hw:0&args=MySoundConfig

For those whom @Sergiy Kolodyazhnyy 's answer didn't work, try replacing alsactl by its complete path (whatever the which alsactl returned to you).

The solution of Sergiy Kolodyazhnyy worked for me. Although I had to add the modification of Exec=bash -c "sleep 5 ...". Indeed this happens because PulseAudio is modifying ALSA.
Another solution is to disable PulseAudio during boot (see here ):

sudo cp /etc/pulse/client.conf /etc/pulse/client.confbackup

sudo nano /etc/pulse/client.conf

Find ; autospawn = yes

Remove the ; and change it to:

autospawn = no

This solution also worked for me, although ubuntu gave me a system program error at start. As I hate this kind of messages, I used the first solution.
