Did a fresh install on a new hard disk.
The GPU was never tested if there is sound through HDMI.

Win 10 Pro x64
XFX RX 480

TV don't have sound. Headphone jack (motherboard) got sound.
Already performed windows update.
Running Crimson 16.6.2
TV is assigned as play back device.

Kindly advise on what to do.

Switch your tv channels back and forth. It works for me.

noted. i will try that. i also haven't test the other 2 HDMI port.

go change default output device in sound settings

This sound silly

- Have you switch up your volume?
- Have you plugin properly to your device?
- Have you tested your HDMI with other device?
- Try to run a driver updater

If not mistaken, that option is grayed out. Already disabled and enabled back TV in sound settings.

The rest i will do tonight.

did you check if you were using the HDMI oputput as your default??? right click the sound icon on the bottom right>playback devices> and right click your hdmi output as your default device.... holla

can close thread. solved after disable all audio devices and enable all back in sound settings.
note that it's the only thing i tried.

You need to switch your playback sound to HDMI. Windows will not set your HDMI sound output as default. Right click on the speaker icon at the tray. Go into playback to change your default sound output to HDMI.
