How to fix alsactl store that does not save alsamixer settings

Bianca Luísa — Sat, 13 Feb 2021 02:14:16 +0000

These days I had problems with alsamixer settings on my Ubuntu version 18.04.5, it wasnt being restored when restarting the system. I solved the problem by doing this:

Open the alsamixer

1- sudo alsamixer

Make the changes you want. Save changes with

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

Open bashrc

3- sudo nano ~/.bashrc

Add this line at the end

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

save and reboot.

alias to toggle your microphone using terminal

Bianca Luísa — Thu, 15 Oct 2020 00:31:49 +0000

If you type it on your bash, you will alternate your microphone on/off switch (toggle). If you are using ubuntu 18.04 open a terminal and type the command below:

echo "alias mic='amixer -D pulse sset Capture toggle'" >> ~/.bashrc && . ~/.bashrc

now when you type mic on your terminal it will alternate between muted or not.

Problem upgrading Ubuntu 18.04 on a Dell computer

Bianca Luísa — Thu, 15 Oct 2020 00:19:16 +0000

Last week I had an interesting problem with ubuntu 18.04. I updated the system using 'sudo apt-get update && sudo apt-get upgrade' and for my surprise when I restarted the computer I had no sound e no mic. The only output was Dummy Output. I tried everything tutorial.
So I decided to reinstall using USB boot. Ok... Everything was working fine until the update, AGAIN!
I reinstalled again!
This time, I decided to update using Software Update and it worked!! I don't know why but updating ubuntu 18.04.2 to 18.04.5 with sound and mic functioning properly, just using the Software Update. Is this problem only on Dell G3 3590 or is it a general problem?

(sorry my english, rs)
