Not sure what troubleshooting you have done – have you attempted to network connect idr to the t112 directly, so to create a 3 node network – idr, t112 and surface? This would eliminate possible issues with your switch.
Yes big time – thanks for the tip – I was able to configure groups segregated by Vox, instruments, drums and no-FX – then routed to the stereo MTX…all good, so I am feeding the CD and Livestream audio….so I thank you !!!! RG
