I have a simple set up, AHM 16 with an IP8 and an AR84 Audio Rack expander. I have everything connected to a tp-link gigabit switch. I have updated the AHM to the most up today firm ware. I am connected with a m2 Mac book pro. The issue is I had everything working then all of a sudden no sound. The AHM recognizes audio the IP8 even shows audio but nothing through the speakers. If I go into the i/o patch it will work direct connect but not with the IP8 slider. Please any help is appreciated. ---

What you mean with “expander”? ---

Yes the Ahm16 is connected to the ar84 through s-link. Then the AHM is connected to the router with the IP8 and computer. ---

I am a novice setting this up for a church event. So I’m just learning. I did this following the instructions as best I can. ---

I can see from your Inputs and Zones screenshots that all your faders are in the off position - as well as setting the level for the end of the input signal path, you need to set an output level. Don’t also forget to check in your crosspoints in the Zone view - these levels will likely have defaulted to off /-inf dB too. Feel free to attach the config if you’d like us to verify it. ---
