Many videos are HD Audio which may be blocked except for protected audio connections (HDMI is one of them.) So USB might be OK for making noise with Windows but not playing DVD or BD.
Also, there can be an issue on the decoder side.
Bottomline. This has serious limitations and won't work under a lot of scenarios. The maker will be the one to tell you more (education) as well as tell you what drivers and settings to use.
All I know is this must be broken since the HDMI consortium demands that the audio and video channel be secure under certain conditions. USB is not secure.
So my hdmi port was busted. I shelled out 30$ for a usb to hdmi adapter. I followed all of the instructions and finally thought my problems were solved. Nope! It wont play any audio through my tvs speakers. The only thing J5creates website says about this is to switch my audio source to usb Audio. Which I did, yet it still does nothing.
Im using a j5 usb to hdmi adapter Model JUA254. Im at my wits end on how to fix this.
Ive tried setting the cable audio as my default. Updating all my drivers. No luck with any of that. If anyone has any idea please let me know
