Playing iTunes through Bluetooth speaker on Windows 10

I have followed all of the instructions and YouTube videos that I could find to explain why I can hear everything else on my PC through my desktop Bluetooth speaker, but my iTunes still will not play through the speaker. Playback is on Direct Sound. I have closed iTunes and restarted it 10 times. I have restarted the computer after doing so as well. I even uninstalled iTunes and reinstalled it to no avail. What else have I not tried?
