Synapse 4.0.86 prevents my system from sleeping if my Razer USB headphones are not connected. `powercfg -requests` says “An audio stream is currently in use”. But if I connect the headphones or quit Synapse, the message goes away. I cannot imagine what nonsense thing Synapse is doing that holds open an audio stream. Any ideas for fixing this? Or reporting a bug?
If it matters, I also have Razer keyboard and mouse connected.
