I use a high quality headphone which capable of producing really great sound. On another computer and on various OS, it was able to produce some deep bass sound. I previously used my headphone on a Lenovo L540 (with Windows, and so Lenovo provide Windows drivers).
I recently changed for a new L540 and a fresh Fedora. The problem is that the sound is now a little bit more "flat" and lose its deep bass.
Even if I look on the Internet how to enhance sound on Linux, I only found how to use
alsamixer to put the sound beyond 100%.
Do you have any idea on how to enhance sound quality on Linux ? I DO NOT want a music player with equalizer, as I would like to enhance sound for all my sound streams (Youtube, VLC, ...).
