iplayer individual song volume not working on my MacBook Air

You should be able to use the volume controls build into the top of the computer. If it doesn’t work, try restarting, or reinstall macOS from recovery. See How to start up from macOS Recovery - Apple Support

You have the M chip. How do I know? Because no other MacBook Air can run macOS 26.

And it is ok. I mean, the Apple Music is the built in player. Don’t forget, next time post this in the Apple Music section. I will ask that this get moved to that section.

What do you mean?

Are you talking about the BBC iplayer? If so, then you need to take this to BBC, not the apple Community.

Are you talking about the Apple Music player?
