Hi xor
Audio settings for newly installed extensions should never default to full volume. An unsuspecting user could damage their
speakers. Or worse, if wearing headphones, cause hearing damage.
1. as; this is like a sound system switch. the key must be open (unfortunately, the key is closed.)
2nd place; youtube player or VLC player comes with low volume adjustment. (in other operating systems this setting is usually 100% on the control panel
3rd place; headphone subject
but the sound that hurt the ear
Sound amplifiers with amplifiers may damage the ear.
but there is already an option to manually adjust the volume.
In this respect, the levels of these settings should be certain.
