Stretch, pulseaudio and bluetooth headphones

[Mark Fletcher <mark27q1@gmail.com>]

Hello the list!

Quite a while ago I bought a pair of Bang & Olufsen bluetooth headphones 
and have been using them from Jessie.

The list may remember I had a little bit of a struggle getting them to 
work with Jessie, which eventually turned out to be because I 
unknowingly had 2 instances of Pulse running...

After that all has been working great, until I upgraded to Stretch.

After the upgrade, I was getting only mono sound. 

I followed the instructions I found here --> 
https://bbs.archlinux.org/viewtopic.php?id=197482https://bbs.archlinux.org/viewtopic.php?id=197482

and moving the command to load module-bluetooth-discover so it isn't run 
until X starts as described there fixed it. But I am not very 
comfortable with the solution -- it feels like it is likely to get 
undone in the future by an unsuspecting package upgrade.

Anyone else seen this? Are there better solutions to be had? (Solutions 
that aren't likely to fall apart after I've forgotten what I did)
