HifiBerry + DAC Help - no "sndrpihifiberry"?


I just got a HifiBerry +.
Previously, I was just using the 3.5mm for audio out.

I am not getting any output from the DAC at this time.
When I set it up in Volumio, I picked I have ‘HifiBerry +’ as i2s driver, and ‘Hardware’ as volume mixer control.

I was seeing in these forums that I should select ‘sndrpihifiberry’ as audio output.
However, I do not see that as an option, only ‘ALSA’.
Am I missing something?

Thank you.

As far as i remember, you need to reboot after selecting the i2s DAC before sndrpihifiberry appears as an option??

You followed this to start with?
