I am using Steinberg UR22mkII DAC (digital analog converter) for managing speakers. Steinberg is connected to computer via USB. This is my used SOUND OUTPUT in settings, so I can adjust volume at the top bar on a desktop.
I also have primary Samsung monitor on HDMI and projector on HDMI (but never use it for sound). All 3 devices (Steinberg on USB, Monitor on HDMI and Projector on HDMI are always connected to computer), but the projector is most of the time turned off.
In Settings/Sound/Output I have 4 options:
- Digital output (S/PDIF) - Integrated sound
- HDMI/Display port 6 - Hawaii HDMI Audio [Radeon R9 390]
- Digital output (S/PDIF) - Steinberg UR22mkII
- Analog output - Steinberg UR22mkII
I always use third option in settings, but after shutdown/reboot, selection changes automatically to the first one. So I have to choose third again. Every time since I upgraded to Ubuntu 19.10. On Ubuntu 18.04, there was no problem.
Thank you for help :)
