Possibility to use jack input with Hifiberry Dac?

I have a R-pi + Hifiberry Dac.
I’ve changed internet provider, and while radios streams are fine, Spotify tracks and Spotify connect are interrupted systematically after few minutes.

This plus the playlist display issues: I’m considering using external device such as Google Chromecast, to stream from Spotify.

Does anyone know if is possible to use the input of the R-pi to get stream in (from Chromecast or Smartphone), and still use the Hifiberry DAC output ?

Many thanks.
