After connecting my GTX 980 Ti to my Onkyo TX-NR509 receiver via HDMI I have the following situation:
nvidia-settingslists HDMI-0 as connected and even shows the name of the receiver.
pavucontrollists GM200 High Definition Audio (so it's not this common issue) but all the profiles are listed as "unplugged" and "unavailable".
- The receiver says "No Signal".
How do I convince PulseAudio that the receiver is connected?
