No sound on Linux
When Xeoma is installed to autostart on a Linux system, it runs under “root” user. By default, “root” does not have access to audio, that is why you can’t get it to play back your own files.
You can either run Xeoma under a normal user (without installing to autostart) or use a workaround to provide sound for “root”. Read the instruction on how to do it by the link: https://www.computernetworkingnotes.com/linux-tutorials/enable-sound-service-for-root-user-in-ubuntu-linux.html
