I plug my headset today after some months, maybe the beginning of the year.
There was an update of PiTool I did, and after that, my HDM remains black, error 10600.
I installed the 126.96.36.199.Beta
It suggested me to update the firmware. I did and then my HDM was working again.
I update PiTool and install the 188.8.131.528 from PiTool itself
After the update, it suggest me a new firmware update, that I did
And now, again, my HDM remains black.
That’s pretty weird. Have you tried manually installing the newest firmware? When I had judder issues and had to keep reverting to .144 I had a myriad of weird issues sometimes. Sometimes it’s as if pitool doesn’t install right… Crappy answer I know, but I’d recommend completely uninstalling it all, installing pitool .258 and manually doing the firmware. This has corrected funky issues for me in the past.
