headphone volume auto-set to loudest

Status changed to 'Confirmed' because the bug affects multiple users.

I have no observed this on vivid+overlay, but I have been on wily+silo 038 recently and on a walk back from town I observed the 'random' increases of volume for short periods of time at the start of a new track.

However I don't think this was related to notifications, as mobile data is broken on wily, and the wifi was not connected (but it was scanning for new hotspots constantly with buses going past that it could have connected to).
As it appears to happen when a few seconds into a new song I feel it could be related to when the usermetrics are incremented (when >5s into a song).

I'll continue monitoring my device to see if it can be made reproducibly.

Can confirm on MX4

happened numerous but random times in the music app when a new song begins. hurts ears

If anybody experiencing this problem can begin to try and determine a pattern of how to reproduce this issue, that will go a long way in getting this fixed. I agree that this is a very undesirable bug for very obvious reasons.

bug #1478506 seems to be related here...

@ogra Indeed, I think that's probably the best lead so far in reproducing this.

Do not happen anymore here since music-app recent updates.

That's good, reopen this bug if you come across it anymore.

Happens again this morning, while switching tracks in music app
