Audio Device and Sound Bug

I noticed when you start PoE1, it chooses the default audio device from your windows settings to play audio from but the audio setting in-game is not refreshed to the current one used.
E.g. I change the audio device in-game to my monitor speakers then close the game and set the default audio device in windows to my headphones and start PoE again I have audio on my headphones but not on the speakers although the ingame settings show I have selected the speakers. What makes it even weirder is that when you change the ingame settings now from speakers to headphones the audio appears on the speakers.
Another thing I have noticed is that the delerium effect, which shoots out ice bolts when you kill the affected mob ignore this and other sound settings too.
E.g I run a map with deli and rolled the mentioned affect on the mobs and had the speakers selected ingame but was hearing the "normal" audio on my headphones anymore. I then turned down the master volume to 0 so I had no sound on my headphones. But the mentioned delirium effect still made sounds but not on my headphones it was coming from my speakers. Then I swapped the audio device to my headphones. Now I only hear the delirium effect on my headphones and nothing else.
It seems like different audios choose diffrent sound settings, when there should only be one sound settings.
