Hi,

Recent purchase of the Raspberry Pi from Core. I am using the device with PlayoutBee (video play out device) however I cannot get audio over HDMI.

I have searched for solutions however nothing has worked. 3.5 mm jack works and so does a USB headphone amp on VLC, Chrome and FireFox.  
I am sure there is a simple fix as I have been debugging on a vanilla version of the OS.

Any help appreciated.

Regards, Craig

Hi there, @Craig303545, and welcome to the forum. Glad to have you here.

Would you be able to upload a picture of the device and how everything is wired together? The Raspberry Pi 4B actually has two mini-HDMI ports and some users have stated that only only the port closest to the Power Supply has audio.

Hi Jane, I will do. I can confirm I am using HDMI port 0 (closest to USB power) after reading same in forums

Hey @Craig303545,

What device are you trying to play audio through? Some HDMI monitors don’t correctly advertise their audio capability, so the Pi doesn’t enable it. A quick test is to plug into a TV or another HDMI display, if you get sound there, your original display likely has an EDID compatibility issue.

If you’re sure the display should support audio, try forcing HDMI output. Open a terminal and run:

```auto
sudo raspi-config

```

Then going to System Options → Audio and explicitly setting HDMI as the output may work.

There’s also an older [forum thread here](https://forums.raspberrypi.com/viewtopic.php?t=260936) where user Optimavisi seemed to have success in Nov 2020 by running

```auto
sudo apt update
sudo apt -y purge "pulseaudio"

```

This may be outdated by now.
