In-store Radio audio issues

We are trying to get audio out on the In-store Radio package.

If we add the “alsa” file to the config folder we were able to get audio through the HDMI however it is choppy.
We purchased the recommened DAC “HiFiBerry DAC+” and installed it on the unit but we were unable to get audio from it.
Has anyone had success with the headphone jack or a DAC?

I’m trying to look into that. I’ve added the

dtoverlay=hifiberry-dacplus

to the /config/userconfig.txt file. That helped with getting the alsa device up. I’m currently trying to figure out how to select that for playback. Finally /config/alsa needs to be set to hifiberry. At least from here it seems like it should now play sound.
