Last week I tried to switch audio to HDMI. I succeeded by using this script: https://wiki.archlinux.org/index.php/Pu … io_to_HDMI
I did not add a udev rule and I did not create a service. I just copied the script and executed it. It worked fine.
But thins this date I don't get any audio on my laptop audio. I called the script when the hdmi cable is plugged of, but I only get the message: "Fehlgeschlagen: Entität nicht vorhanden" ( I don't know how to get an english error message or what the message in english could mean).
A workaround is to plug-in and plug-out earplugs. After this, the audio works fine.
Do you have any idea what happened and what I have to do, that the audio works without the workaround?
