Very strange, for sure. I'm not familiar with the problem you are having, so I'm going to have you try a couple of things-
First, verify the output device of the commands that work and compare them to the ones that do not work. Your first message said
All of my device settings are to default to the headphones
and then goes on to say
all devices are set to my Razer headphones.
You have the option to either leave the device as set to the default audio device, or select a specific device - just need to make sure it's lining up.
If it is indeed going to the Razer headphones (that is the action says that it's going to the Razer headphones), there may be something up with the cached device id. I would try changing to another device, saving, and then set to the Razer headphones again to see if that works. I would also give the 'default' device a go as well.
If those do not work, I would try recreating a broken command from scratch to see if that solves anything (it's possible that your data has somehow gotten borked).
