The current impact of this problem is that the sample music does not play on internal Pelux-based images. This is because QTIVIMEDIA_SIMULATOR_LOCALMEDIAFOLDER/home/root/media is set in neptune.service but it is not passed to "ivimedia-simulation-server"

Despite of this particular variable, IMHO, there should be a set up in which Qt Auto related processes can share a common set of env variables.
