audio_output_enumerate_devices() throws exception

This method does not work for me:
)
Should I be able to use result like this to change audio output device?
I ask, because I get very different results. Sometimes it works, sometimes it doesn't.
E.g. If the module is alsa, it always ends playing on the internal notebook speakers, no matter which device I choose (including HDMI). But if I select pulseaudio module, it always plays on the HDMI device. Cant' figure out a pattern and would like to rule out it is the way I enumerate the devices.

I wrote my own method for this, but I am not sure it is fully equivalent (obviously cant't compareTraceback (most recent call last):
