Thank you for posting and welcome to the community. I'm sorry to hear that you are not getting any audio when using HULU on your TV and I would be happy to help with this.
Just to clarify with you, do we still get audio if we switch back to other sources on the TV? Is it just HULU we are unable to get audio from?
As we may need to look at some settings on your TV for this what make of TV are we using? If you know the model number as well, that would be very helpful too.
Also, are we using the HULU app on your TV? Or are we using it through an external streaming device?
I look forward to hearing from you.
