As I understand it, you can use a standard sound device like a
Digirig to do modes like Dstar (GMSK), YSF (C4FM), and P25-Phase1
but DMR requires deeper control of the RF waveform.? As such, you
need an RF board like a "MMDVM hotspot" board / a Zumspot board /
DV-Mega / OpenSpot appliance / etc (which can do all modes btw):

Here is one guide I found on how to set this all up yourself:

If you rather buy something pre-built and with support, consider an
OpenSpot:

I found a bunch of stuff about DroidStar and other
stuff using an AMBE
dongle, but, so far, nothing about how to interface it to a radio.
They
all seem to be some kind of interface to on line nodes like
AllStar.
My goal is to be able to use P25 and DMR on an existing analog
radio via
a RaspberryPi and audio interface.
Thanks,

Droidstar allows all but D-Star to work
without the AMBE chip including
the new M17 mode. Google it.
