Noise when optical input is tuned on but not active

I want to raise an issue.  Not sure if it's hardware or software related.

I have an Amp100 with DSP optical input enabled and set to automatically switch-off other inputs. Optical input is connected to TV.

When streaming with DNLA or Spotify directly to HiFiBerryOS, I hear a crackling noise similar to a dusty needle on a turntable.  This is with TV turned off.   

If I then turn on TV and stream spotify to TV instead, HiFiberryOS switches to optical input and music plays without the noise.

If I turn off the optical input in sources, I can stream to HiFiBerry without noise.  This is a work around that is OK but takes away the convenience of automatically playing TV through Hifi speakers.
