Bug with audio and volume?.

Hi, when I use "play" to play a song in the "music" folder this happens:

You can not increase the volume.
It's useless to put 5-10-30 decibels of volume increase.
You can only reduce the volume, for example using -5.

This is correct? why?.

A volume of 0 dB is the original volume and amplification is not supported. So you can only decrease the volume.

bring all your sound files into a program like Audacity first and use "Amplify" on all of them.

However, this alone will not make them all the same volume, but it's a start. Mastering all sounds to be at the same level is a lot more complicated than just adding volume. Sometimes you need EQ and compression along with gain to help you balance out the sound.

Ok thanks, I have already solved amplifying and doing other operations.
