Adjust the volume in Apple Music on the web
At music.apple.com/au , play music from your library, stream music from Apple Music or play Apple Music radio.
To control the volume, use the volume slider at the top of Apple Music (or adjust your system volume).
Note: You may need to make the window larger to display the volume slider.
If you have the Music or iTunes app on your computer or device, you can open the app directly from Apple Music on the web — just click the link in the bottom-left corner.
