Looking for a permanent workaround for ATC Azure Sound Horror Problem?

I use a headset. If i disable my onboard sound will my headset still get sound signal via HDMI? I use this headset for everything according to my computer.
But i dont understand how this will affect the problem with the Azure sound? To me it seems the Microsoft server has problems and cut off the connection. I would like to connect again since my internet is ok. So i guess the work around will be about that.
Or disabling Azure as proposed and then server problems arent problems any longer to me.
