Crowpanel 7" twitching screen when sound played with speaker

Hello,
I am using a Crowpanel 7" with a speaker connected on the SPK port.
I noticed that when a sound is being played on the speaker (using the library ESP32-audioI2S-master, following the tutorial on https://www.elecrow.com/wiki/ESP32_Display_7.0-inch_HMI_Arduino_Tutorial.html#example2-play-music), the displayed screen twitches from left to right, like there is noise on it.
Is it an issue known to you, and if so, do you have a solution on how to solve this, please?
Have a great day,

  • Mehdi

  • Hello @Elecrow , can I get your take on this, please?

  • Hello @Elecrow , can I get your take on this, please?

  • Hi friend, can you provide a video of the screen twitching from left to right and send your source program? Are you using LVGL to display?

  • Hi @Sun , thank you for reaching out about this :)
    I'm linking a zip file containing a video of the phenomenon and my source code to this message. Let me know if you need the libraries that I use as well.
    Yes I am using LVGL. As you can see on the video there seems to be some kind of interference between the display and the sound : when I press a button on the screen, the played sound twitches as well.
    Please let me know if you need additional info, and thank you again for your answer!
