nvidia-dkms-415.18-1 breaks HDMI audio

The DisplayPort/HDMI audio output of my GTX660 card stops after upgrading to nvidia-dkms-415.18-1. The device is still listed by "aplay -l" but does not produce sound. It appears as off to "pavucontrol". Downgrading to nvidia-dkms-410.78-1 solves the issue, though.

Any idea if it is a bug or a configuration matter?

Same issue here, with a GTX970.In pavucontrol I can list the HDMI GM204 profiles, but all are marked "unavailable" and "unplugged".

Upgrading to nvidia-dkms-415.18-4 do not solve the issue either.

The issue persists with version 415.22-1. Sad!
