Volume increase on song change

So I’m not sure if this is a bug for plasma, fedora, Spotify, or the headset I’m using.

So I have Spotify playing most day during work, and when a song ends and a new begin it increases the volume by one step (5%). However, it doesn’t always do this and it is seems to be random.

I would like some help to troubleshoot what is going on, so that I can provide a bug report to the correct party.

Definitely seems like an issue with Spotify, especially if it doesn’t happen in other apps. I don’t see this while playing music in Elisa, FWIW.

I finally figure out the issue, it is the headset randomly changing the volume because of noise canceling.

It is the same issue with the headset on other computers, with other OSes (windows and macOS both), with other apps (e.g., Kasts)
