Don’t know if anyone has tried or if it’s well known, but I did. There was a brief period where I could wake it with my Xbox series controllers but then valve pulled the feature for bugs which I never experienced.
I first tried with the dongle which wakes it as expected on my Linux desktop and my steam deck. Then I paired it with Bluetooth mode and was able to wake it without issue.
When they first introduced it, my Bluetooth earbuds would wake it up every time I took them out of their case.
Oh man I used poxelbuds with mine at the same time and never had an issue. Like I said, didn’t affect me but it sucks so many had issues.
