HDMI audio output broken after upgrade?

I've been using HDMI audio for a couple months, and it just stopped working. I'm not sure which part of the pipeline is broken, because pavucontrol shows everything normal:

• In the Configuration tab Built-in Audio's "Digital Surround 5.1 (HDMI 2) Output" is selected (the list of outputs show a bunch of other options, most of which are marked "unavailable").

• The Output Devices tab shows only the above device, with "(plugged in)" after the name

• The Playback tab shows whichever application is playing (Firefox, VLC, etc) at 100% volume, and the volume indicator bar is moving as normal.

Other signs that everything is normal:

• The receiver settings are the same as before I rebooted, although I did also restart the receiver at the same time.

• I've not unplugged or re-plugged anything other than the HDMI cable.

• Bluetooth audio works fine.

Basically everything looks normal, but there is no sound. Short of the receiver having thrown a fit (the display looks normal and there's no indication of anything unusual), is there anything else I can check?

Solved by fiddling around with the settings on the receiver for a while. Sorry for the noise, no idea how this happened. It's back after rebooting just the PC. The receiver settings look like they were a red herring; everything works except the actual sound output.

Yeah it's probably not the software.

I'm having this problem recently as well. I checked my update logs and found the following:

Do you have an AMD Video Card?
