Fedora version : 30
Linux version :
5.0.17-300.fc30.x86_64 (updated on 28-May-2019)
My laptop model : HP Omen purchased on 2018 November
My external speakers : Logitech external speaker with subwoofer (Model: Z625)
I attach external speakers to the headphone out of my laptop. It works fine with my Windows 10 (dual boot).
But, whenever I restart my laptop , the volume for the external speakers are set too low.
Below are the few things, I have tried to fix this:
Using alsamixer, I increased the volume of ‘Speaker’ (external speaker, ) bar and tried to permanently store the setting using store command shown below. Although it increases the volume of external speakers , the settings are lost upon reboot of the laptop.
> sudo alsamixer
sudo alsactl store
I mean, whenever I restart the machine, in the alsamixer, I can see that ‘Speaker’ bar (external speaker) is set to zero.
Screenshot below (see the third bar from the left which is empty)
b) Tried installing pulse audio equalizer. Didn’t help
c) Tried installing pulse audio equalizer shortcut thingy. Didn’t help.
d) Installed pavucontrol like below. pavucontrol is pulse audio control. It gave a control panel. But, I still cannot permenantly set the volumne for external speakers.
dnf install pavucontrol
