No HDMI signal from Raspberry Pi 4 after turning TV & Soundbar off and back on

I'm running LibreElec 9.2.1 on a Raspberry Pi 4, connected through a 4 port HDMI switch to a soundbar that's then connected to a Vizio PQ65-F1. When the TV/switch/soundbar are all on and I boot the RPi everything works great. The problem I'm running into is that when I turn them all off (except the RPi), then turn them all back on, the HDMI signal is lost.

So far I've tried:

• Add hdmi_force_hotplug=1 and hdmi_drive=2 to config.txt
• Create an edid file
• Disable CEC
• ssh into the RPi and run "tvservice -p"

The only thing that brings the signal back (outside of a reboot) is the tvservice command. Otherwise, nothing I've done seems to keep the HDMI signal alive. Obviously having to ssh in every time isn't an idea solution.

Is this a known problem with the RPi 4? Or just something obvious I'm missing?

TIA!

Followup: After systematically removing components between the RPi and TV, I found out my issue is an HDMI switch that I'm using. Looks like this is less of a Kodi/LibreElec/RPi issue than it is a hardware problem upstream.
