Bug Description
I can play via bluetooth from my laptop or my mobile phone. I have a set of bluetooth headphones and bluetooth speakers.
Any combination of output with the smartphone as the player works, which is as it should be.
Any combination of output with the laptop as the player is miserable: sound stutters, sometimes randomly, sometimes seemingly when I touch the laptop or come close to it...had similar or identical problems with a previous Ubuntu laptop. Bluetooth audio seems to be in very bad shape.

The main fix for Bluetooth audio stutter is one that you already have, released in pulseaudio 1:11.1-1ubuntu7.1 (bug 405294). People generally don't report problems since then so any remaining issues are likely to be hardware-specific or environment- specific.
Please run these commands:
lsusb > lsusb.txt
lspci -k > lspci.txt
and then attach the resulting two files.
Please also test with:
* wifi disabled completely; and
* using a 5GHz network instead of 2.4GHz
