Me: (damages the cable to my headphones accidentally and now all the audio when plugged in sounds either distorted and/or too quiet even at 100% volume [I usually have the volume at like 40-60% but now at 100% it sounds like it's at 10% volume at max)
The sound test on Linux Mint: (sounds totally fine, no distortion, no too quiet audio)
????????????????????????????????????????????????
(I can use these headphones via BT too thankfully but RANT BT sucks I know this isn't a Linux-exclusive thing but BT has been a thing since the late 90s why is it still so bad!!!!!)
Not sure how broken leads on a headphone can impact sound, but there are some things to try.
First, go into the applets section and download "Sound 150%" by Claudiux. It will extend the maximum volume slider to 150%. Set the slider all the way to 150% while using the basic volume control at something lower. See if that helps.
Other things to try. Install Pulse Audio Volume Control.
On a more exotic" level, another possible issue may come down to what sound hardware and software operates through your motherboard.
IF you're depending on Realtek/Intel drivers, there's a three-step process to improve sound. Though this is primarily based on speaker sound rather than using headphones.
You'll first need to access "File System", and check the box for "show hidden files".
1) Then use root authority in the file manager and access the folder sys/module/snd_hda_intel/parameters/power_save. In this file, change the "1" to a "0" and save it.
2) While still in the sys/module/snd_hda_intel/parameters folder, select the file with root authority named "power_save_controller". In this file, simply change the "Y" to "N" and save it.
3) Go back while still in "File System" with root authority, and select the folder "etc". Then go to
etc/modprobe_d/alsa-base.conf. There will be a number of lines of commands that all begin with the word "options". At the very bottom of them, add the following line:
options snd-hda-intel power_save=0 save_controller=N
Then save it, and exit. Reboot and see if your sound gets better.
There is one last thing to consider, though I use it only in conjunction with a single program, a disk burner called "Kb3" to make volume consistent on digital discs. Though it might function globally to regulate audio on a broader basis. (I'm not sure). It's a terminal command as follows:
sudo apt-get install normalize-audio
Needless to say, getting speaker sound to work and become optimized in Linux between two different computers has been my greatest challenge. Though I can offer no guarantee that these fixes will solve your particular problem. Hopefully the first suggestion will be all you need.
