Remaining questions about the whole setup:
1. What OS and driver version are you using ?
2. Are you using the latest firmware on the HDSPe MADI FX card and on all connected MADI devices ?
3. When you talk about ADI-8 do you mean the ADI-8 QS ?
4. What MADI format do you use ? 64 or 56 channels ?
5. How are the clock settings at the HDSPe MADI FX card ? set to -> internal ?
6. How are the clock settings at each of the connected MADI devices ? -> clock source MADI ?
7. Do you use Auto-CA for delay compensation and does every device show an uniq Compensation ID ?
8. Do you use Redundancy or Mirror Mode ?
9. Whats the specification of the optical cable that you use ? Multimode OM4 ?
10. Do you use structured cabling and thus patchfields in your setup from room to room or between floors
Maybe the cabling between patchfields or the patchfield itself is not ok for whatever reason.
11. Did you mix eventually optical fibre cable standards ? Not sure if this would ever work, just an idea.
1. check whether its related to the HDSPe MADI Port of MADI BUS 1: what happens if you use MADI2 or MADI3.
With this test you have least effort simply to see whether its MADI bus related, by plugging the cables to on the card from MADI1 port to MADI2 and then later MADI3.
I think best or even required for this test is to ensure, that these 2 driver options are disabled:
[ ] Redundancy Mode
[ ] Mirror MADI1 output to MADI2 and 3
2. check for impact of bad unit and/or cable
Connect only one device to the HDSPe MADI FX BUS 1.
Use always the same working cables.
By this you could detect a faulty / misbehaving or maybe misconfigured unit.
Or you detect a cable error while you are doing it.
Once you checked all devices, you repeat this procedure for all cables.
3. Eventually build the setup new in a compact way "one unit over the other"
using new OM4 cables of i.e. 0,5m and a longer cable from this "stack" to your HDSPe card:
Here one example: https://www.reichelt.de/duplex-jumper-s … p;&r=1
So the basic idea is to simplify the setup to be able to nail down a device or optical cabling problem.
Taking OM4 cable is IMHO the best to do as you can use this cable also very nicely for networking infrastructure so that you can stay with one cable type, be it patch or inhouse cabling for 2 purposes (audio and network).
As you might know you need to be careful with optical cables in terms of
- not touching the surface
- not to bend the optical cables too much (supported bending radius)
