Trouble with music output from HDMI 1 & 2 when pi 2 display is on - sriram76 - 06-21-2025

Hi All Experts,

As a newbie (please check my intro), I need some help from you all. I have burned the latest Release: 9.3.6 2025-06-06 into the memory card and booted with my raspberry pi 5. I got the official display 2 for pi and have successfully installed it on the pi and now I almost got everything the libraries are loaded and I can see my music in the display.
However, there is no music coming out of HDMI ports (both 1 and 2) when the native display is turned on. When I turn it off, music comes out. I think the moode is meant for a headless play but I want a display experience for my kids who do not have any phone or tablets.

Is there anyway I can get the music from HDMI while display showing the moode UI on the native screen?

Thanks

What device is connected to the HDMI port?

I don't know what configuration settings (if any) would enable a DSI display plus HDMI audio but if it can work the AVR connected to the HDMI port has to be on before the Pi starts up or the Pit won't detect the connection.

The command below prints a status of the HDMI ports.

Code:
# Print HDMI port status

kmsprint

# Example

pi@lcd:~ $ kmsprint

I tried this but it didn't work. What use is to disable all ports when we connect an audio less display to the pi?
Is there any other thing I can do to get some audio with dsi?

AFAIK the DSI interface does not support audio.

Moode does not disable any ports. I have no idea why the HDMI port does not show up in your kmsprint output assuming the device connected to the HDMI port was on before booting the Pi.
