I am looking for a native Linux software that can increase the audio volume of a video file.

To increase the volume by a specific decibel amount (e.g., +10dB) while copying the video stream:

ffmpeg -i input.mp4 -vcodec copy -af "volume=10dB" output.mp4

To increase the volume by a linear multiplier (e.g., 2x louder):

ffmpeg -i input.mp4 -vcodec copy -af "volume=2.0" output.mp4

Vous avez déjà remarqué comment le volume varie d'une vidéo à l'autre sur YouTube, ou pire, comment certaines pubs sont 10 fois plus fortes que le contenu ...

Linux Mint moved to a new sound server called Pipewire.

To check which sound server is running, use the following command:

inxi -A

If you're unable to get the sound working, you can try to go back to the older sound server called PulseAudio.

apt purge pipewire pipewire-bin
systemctl enable --user pulseaudio
sudo reboot
