It certainly does not switch off. This happens when i watch a movie or YouTube Video. It doesnt depend on the used application. I left the phonon dialog open to change the setup of my audio output devices. This way i can just click on the Task bar to change to the Dialog and Switch it back to SPDIF. Sometimes it switches after 5 secs to analog Audio after i set it again to SPDIF, sometimes i dont need to bother for 2 hours. It is not an option to replace my desktop mainboard because of this. There is also no event that something failed in dmesg. The hardware is reliable when i use alsa. So it is pulseaudio. Debugging pulseaudio seems like a ..... challanging task as i downloaded the sources and rebuilt it for myself to investigate the issue. Is there an option to just disable the automatic switching of sinks?
