I think I managed to capture this happening in a logcat, will post that in gitter. This also happens to me on occasion, also using LOS 15.1 on OnePlus 5T. From experience, it seems to happen when getting towards the end of a longer (10+ minute) song.

I've been having this issue since I started using Ultrasonic. I have to "force stop" it to get the second track to stop.

I'm running LineageOS 15.1 on a Oneplus 5T. I can dig a little deeper, perhaps post a logcat if it would be helpful.

This happened to me again a week ago while driving. Also a long song. Freeze, then both instances started playing at the same time.

Any update on this? This is a super annoying bug. I'm taking a stab in the dark as to what could be causing this, could it be related to MenuDrawer? I see a default duration of 600 for a menu animation, could it be when that duration is reached during playback, that's what triggers the behavior?

 endDrag();

 final int dx = position - startX; 

 if (dx == 0 || !animate) { 

 setOffsetPixels(position); 

 setDrawerState(position == 0 ? STATE_CLOSED : STATE_OPEN); 

 stopLayerTranslation(); 

 return; 

 } 

 int duration; 

 velocity = Math.abs(velocity); 

 if (velocity > 0) { 

 duration = 4 * Math.round(1000.f * Math.abs((float) dx / velocity)); 

 } else { 

 duration = (int) (600.f * Math.abs((float) dx / mMenuSize)); 

 } 

 duration = Math.min(duration, mMaxAnimationDuration); 

 animateOffsetTo(position, duration); 

 }

That doesn't seem to be it, but whatever is causing it, it's calling writeObject.

Any updates on this? I just noticed that with Android Q (stock Pixel 3 ROM) that it now will stop the first song and the second "headless" one takes over, whereas with Android O and P it would play them both simultaneously (that was OnePlus 5T on LineageOS though).

EDIT: I wonder if 2.6.2 may have fixed this? Since updating I haven't been able to reproduce this. I'll do some more testing.
