With EESDR V2, you can mute Line Out 1 and Line Out 2 in RX1 and RX 2 with the E-Coder Pro.
I use a different set of speakers per RX.
I've tried different settings V3 but can't get it to work.
When I use Line Out on V3 and set my different speakers there in RX1 and RX2, I have sound on both RX but cannot switch it off independently like in V2.
How can I set this in EESDR V3 0.12.1.
Post some pictures of the setting here.
