Hi all,

I'm using Hd Native PCIe with configuration as below :
- HD Sync as Master Loop sync , receiving clock master from Hilo.

- HD IO (16 analog in - 16 analog out ) on port 1 using mini digilink ( long cable from Avid ) , 192 IO ( 8 analog in - 8 analog out - 8 AES ) to expansion port on HD IO
- Hilo on Port 2 via LT-HD card.

The problem : with above config, HD IO, 192 IO and Hilo recognized fine in PT Ultimate 2021.7.0 with A , B and C respectively. However, when I sent a tone from 192 IO and route it back to the same 192 IO I can see the output/in LED shown on the interface but no signal is shown in Pro Tools.
As in attched pictures, I'm trying to route from output 1 of 192 IO back to Input 2 on 192 IO. LED meter showing signal present but in PT , nothing! HD IO, Lynx receive signals just fine! Very weird!


Please help!
