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?
