ISS and Digital Sensitivity

Hi,

This has been disussed here already a bit:
https://support.genelec.com/hc/en-us/community/posts/17531539394578-8381-with-Auralic-ISS-problem?input_string=ISS%20and%20Digital%20Sensitivity

But I have suggestion, not sure how feasible it is, but I do have similar issue. I have already contacted the manufacturer of my streamer that could they add an option or delay to fully shutdown SPDIF output when in idle/paused, but it is worth to ask here too.

So about ISS:

1. keep the prioritise digital
2. keep the sensitivity of analog (low, medium, high)

But allow sensitivity to affect digital too, like this:

1. high = just as now, any signal even bare clock/carrier signal, keep on digital and do not sleep.
2. medium = if there is only digital carrier signal, but actual data is just exactly zeros (aka no data), switch to analog if there is signal and go to sleep.
3. low = same as 2 but also check that digital level is high enough (comparable to analog)

Or if preferred and wanting some backward compatibility this could be another setting in GLM for people to opt-in.

This would allow automatic switching between analog and digital. Many streamers tend to keep the clock/carrier signal going even when paused or in idle/sleep mode. This is likely to avoid any reclock/reconnection delay or even clicks and pops that might happen. But this does not work well with automatic input switching and sleep functionality. This would give a flexibility in home environment where you can have both analog and digital connected.

What makes this issue worse is that GLM adapter even when plugged in to power cannot change the group with remote. So you cannot use separate analog and digital group to manually switch between them without computer or 9320A.
