Okay, so I got Vega 15 Pro and tried to look everywhere on how to fix this problem, but I can't seem to find it.

so I opened it clicked new project and says unable since my auido was off. tried evrey auido option doesn't let me. I try to input clips and says "The playback device  does not support the current output format.
The playback device  does not exist."

I cant play my clips that are in the stuido since it says "Error occurred while starting playback. the request is not enable for this device"

Anyone got anyhelp? I will respond to all comments giving details like my specs and how i recorded it and all.
