11 months ago A very quiet sound is produced, you can verify this by recording mpv's sound output and loading it in Audacity or some other spectrum analyzer, or by setting your audio server/headphone volume to the max.
Imo a better issue would be discussing if there's any utility to having 1 to 10% of the volume control be inaudibly quiet, but I don't really think that's an issue.

Important Information
Reproduction steps
Play any audio file with
mpv --no-config --volume=12 --audio-format=s32 <file>.Expected behavior
A very quiet sound should be produced.
Actual behavior
There is no sound emitted at all. This can be reproduced with Pipewire sound server and with ao pipewire, pulse and alsa. The jack ao is also affected but at volume=3 instead.
