I have issues with external displays.
Disconnecting a display appears to break all of my USB ports until I restart the computer.
- I can hotplug a regular USB device
- I connect a display. Works fine.
- I disconnect the display.
- The USB port is no longer functional.
udevadm monitorreports no kernel events.
xrandralso does nothing.
dmesgdoesn’t report any USB events.
The camera and microphone can disconnect and reconnect just fine though.
Audio over HDMI works on all displays I’ve tried except for one–a 4K Roku TV at my friend’s house.
Doesn’t matter what I do, enabling/disabling audio sources, increasing volume (both on laptop and on the TV)
The Roku TV doesn’t appear to receive an audio signal at all.
