      Description

      When trying to run Examples/Qt-6.2.3/multimedia/video/mediaplayer application on imx8mm-lpddr4-evk, imx8mn-ddr4-evk and imx8mq-evk devices, the devices get stuck.

      Looks like it gets stuck when starting pulseaudio server.

      Only happens on these target devices.

      Only a reboot helps to "solve" the jamming.
