Hi, I installed the latest Hifiberry OS release on a pi 4 and connected my media center, ps and so on over optical cable to my DAC+ DSP. Now I can't change the master volume in the web interface nor by the remote control. Moving the slider just impacts other sources, not the optical one. This is especially bad, since I can't change the volume on my devices (I guess due to the optical connection). Does anyone has an idea how to fix this? Thanks for any idea.
