[miladloveboth]

hi guys
i crosscompile raspberry pi with Ubunto-QT5.12.5 and i made a small music player with qmultimedia
so when i run it on my ubunto everything is ok but when i run it on raspberry i cant hear the music because raspberry use the HDMI audio OutPut
but i want to hear it on Analog jack Headset
so how can i switch it to Analog Jack?

Assuming you are using Raspbian on the Pi, R click on the audio icon on the task bar and select analog output.

pretty elementary....

the underlying OS's sound (HDMI, analog) is operational, and you yourself has proven that.
your DIY built app does not output sound at analog

check your app's code (and dependencies) again and rebuild it if necessary.

In some rare cases, it is necessary to edit config. txt to force HDMI mode (as opposed to DVI mode, which does not send sound). You can do this by editing /boot/config. txt and setting hdmi_drive=2 , then rebooting for the change to take effect krogerfeedback

I struggled with this a lot using an hdmi to vga adapter (i'm repurposing an old monitor with no hdmi port).

What i did is add the following lines to my config.txt then reboot:

dtparam=audio=on
hdmi_ignore_edid_audio=1 #this is to force the sound from being routed from hdmi to 3.5 mm headphone jack.

Hope this helps!

If not you could experiment on toggling some other configs that is documented at: https://www.raspberrypi.org/documentati ... t/video.md
