JustBoom DAC Zero with Volumio 3 release

Does anyone have a JustBoom DAC Zero working with the release of Volumio 3 (launched 7 Dec, not beta version)?

I have had no such luck. I am running version 3.165 on a Raspberry PI Zero WH. My selected I2S device is “JustBoom DAC Boards”. The user interface shows media playing, but no signal comes over the line (or headphone) out.

I appreciate any information or suggestions.
