I have a similar issue with a pair of Turtle Beach Stealth 700 headphones for the PS4. I've finally figure out that the audio goes out everytime there is a lot of wireless traffic. I can recreate the problem everytime with a large file transfer or speed test.

It was worse when I used the M9, but got slightly better with the X60, still a problem though. I don't think there's much that can be done since we do not have options to manually set channels on the Deco (not sure that it would even be able to be fix it anyway)

While I know this is useless, and you probably wouldn't want to do it since it'll create issues with other devices, but disabling 2.4ghz on the M9 will fix your Bluetooth problems.
