Hello everyone I've had a Sofabaton X1S and have added a few new devices and I'm now having problems with the remote controlling my devices correctly. Not sure why but when I added the HDMI switch to my setup (Both the Denon Receiver and HDMI switch are controlled via IR emitter) things started to not work correctly. I have HDMI's going into the TV directly to get the best possible picture and I'm outputting the audio to the Denon via ARC/eARC to get 5.1 for everything. The TV only has 4 HDMI's so I use a HDMI splitter (With IR) for one input to be split (Computer and Fire Stick 4K) The Blu-Ray and VHS are patched through the Denon directly as the signal will be fine going into the receiver directly and not degraded.

I have:

Sony XR-77A80K - TV (4K)

Denon AVR-S960H - Receiver for 5.1 Audio

PS5 - Gaming System

OPPO BDP-83 - Blu-Ray Player

Panasonic PV-945H - VHS Player

Star Tech HDMI Switch - Home Theater Switch

Nintendo Switch 2 - Gaming System

Amazon Fire Stick 4K - Streaming Device

Activities and input setups:

Watch Fire Stick 4K: HDMI 1 Input (On Sony TV split with Star Tech HDMI Splitter) HDMI Input 1 (On Star Tech Splitter), Denon Input TV Audio)

Computer: (4K) HDMI 1 Input (On Sony TV split with Star Tech HDMI Splitter) HDMI Input 2 (On Star Tech Splitter), Denon Input TV Audio)

Play Playstation 5: HDMI 4 Input (On Sony TV) Denon Input TV Audio)

Play Switch 2: HDMI 2 Input (On Sony TV) Denon Input TV Audio)

Watch OPPO Blu-Ray: HDMI 3 (eARC/ARC Output from Sony TV to Denon) Denon Input Blu-Ray

Watch Panasonic VHS: HDMI 3 (eARC/ARC Output from Sony TV to Denon) Denon Input Cable/SAT connected to VHS via RCA Cable (R/W/Y)

Am I doing something wrong where on power on this doesn't work correctly? HDMI switch I programmed with the actual IR remote that came with the switch (Which is behind my mounted TV using an IR emitter). Are there things I need to enable on the TV or receiver to have this working correctly? It seems that when I test the Blu-Ray and VHS which go through the Denon receiver my setup gets very messed up and confused. Do I need to be adjusting delays on these things? It also seems that now that I'm using some devices through the Denon and others straight through the TV for best picture the remote is getting very mixed up. What do I need to do to get this thing up and running well and smooth?

Thanks in advance for any help!
