The setup :
RPi4 running the lastest Hyperbian. Connection via wifi + Usb grabber with HDMI passthrough + Philips Hue liights in entertainment area.
The PI and grabber are powered off the usb of a HTPC and turn on and off with the PC's power.
The issue :
At first everything works perfectly. But some times the lights just stop and freeze. Not a big issue I just remote into Hyperbian, disable and re-enable the configuration in Dashboard and all is good again.
But now having changed nothing the lights will not start at first power up. Checked in Hyperbain dashboard and find LED status is disable after each reboot. So disable / re-enable the configuration in dashboard and still no effect. So go into LED Hardware and change any setting and save. This seems to tickle the LED's in to working and staus remains enabled from that point on and everything is good. Until a full power off and on at which point LED's are back in disable status and you have tickle the settings again to get them to fire up.
Any ideas welcome, any thx.
