Cannot choose I2S in Output Device field

[Curiousgeorgia]

Update:  The only HIFIBerry option under Named I2S Device that populates an option under Output Devices is "HIFIBERRY DAC".  If I choose that under Named I2S Device, it shows it as an option under Output Devices??  I have yet to have any success in passing test audio, but it appears that there might be an issue with the HIFIBerry devices that are populated in Moode??
