The quick fix is this sort of hackery, where the resistors are 50 ohm, and capacitor is 100nF. The capacitor may not be required, in which case you could use just a 100 ohm across the transformer:
Note the ethernet has other issues on the build - may need to remove the crystal (TBD)
Ethernet jack is missing:
Here is the dev board reference:
Here is Sonata:
