Thanks for your response. I had not tried the following tutorial: [HowTo] Bluetooth headphones paired, but no sound after a while.
After following the tutorial it does seem to resolve the issue. Still need to check whether the solution is persistent, but I’ll mark this as the solution for now.
As taken from a similar StackOverflow discussion: “… the problem is that the PulseAudio Bluetooth module is loaded before X11 …”.
Is there a way to otherwise ensure that the module in question is loaded after X11?
Thank you for your patience.
